OXYTETRACYCLINE TABLETS BP 250mg
Ashbourne's Pharmaceuticals Product Only
Oxytetramix ® 250
Oxytetracycline Tablets 250mg
Each tablet contains 250mg Oxytetracycline Dihydrate PhEur.
Yellow film-coated tablets.
Yellow, circular, biconvex film-coated tablets, impressed “C” on one face and the identifying letters “OT” on the reverse.
Oxytetracycline is a bacteriostatic broad-spectrum antibiotic, active against a wide variety of Gram-positive and Gram-negative organisms.
Infections caused by oxytetracycline-sensitive organisms include:
1) Respiratory tract infections: Pneumonia, whooping cough and other lower respiratory tract infections due to susceptible strains of Streptococcus pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae and other organisms. Mycoplasma pneumoniae pneumonia. Treatment of chronic bronchitis (including the prophylaxis of acute exacerbations).
2) Urinary tract infections: caused by susceptible strains of the Klebsiella species. Enterobacter species, Escherichia coli, Streptococcus faecalis and other organisms.
3) Sexually transmitted diseases: Infections due to Chlamydia trachomatis including uncomplicated urethral, endocervical or rectal infections. Non-gonococcal urethritis caused by Ureaplasma urealyticum. Oxytetracycline is also indicated in chancroid, granuloma inguinale and lymphogranuloma venereum. Oxytetracycline is an alternative drug in the treatment of gonorrhoea and syphilis.
4) Skin Infections: Acne vulgaris when antibiotic therapy is considered necessary and severe rosacea.
5) Ophthalmic infections: Trachoma, although the infectious agent, as judged by immunofluorescence, is not always eliminated. Inclusion conjunctivitis may be treated with oral oxytetracycline alone or in combination with topical agents.
6) Rickettsial infections: Rocky Mountain spotted fever, typhus group, Q fever and Coxiella endocarditis and tick fevers.
7) Other infections: Stagnant loop syndrome. Psittacosis, brucellosis (in combination with streptomycin), cholera, bubonic plague, louse and tick-borne relapsing fever, tularaemia, glanders, melioidosis and acute intestinal amoebiasis (as an adjunct to amoebicides).
Oxytetracycline is an alternative drug in the treatment of leptospirosis, gas-gangrene and tetanus.
Posology
Oxytetracycline should be given one hour before or two hours after meals, since food and some dairy products interfere with absorption. Therapy should be continued for up to three days after symptoms have subsided.
All infections due to Group A beta-haemolytic streptococci should be treated for at least 10 days.
Adults (including the elderly) and children over 12 years: The minimum recommended dosage is 250mg every six hours. Therapeutic levels are attained more rapidly by the administration of 500mg initially, followed by 250mg every six hours. For severe infections, the dosage may be increased to 500mg every six hours.
Children under 12 years: Contraindicated in this age group.
Elderly: Usual adult dose. Caution should be observed as subclinical renal insufficiency may lead to drug accumulation.
Renal impairment: In general, tetracyclines are contraindicated in renal impairment and the dosing recommendations only apply if use of this class of drug is deemed absolutely essential. Total dosage should be decreased by reduction of recommended individual doses and/or by extending time intervals between doses.
Dosage Recommendations in Specific Infections:
Skin infections: 250-500mg daily in single or divided doses should be administered for at least 3 months in the treatment of acne vulgaris and severe rosacea.
Streptococcal infections: A therapeutic dose of oxytetracycline should be administered for at least 10 days.
Brucellosis: 500mg four times daily accompanied by streptomycin.
Sexually transmitted diseases: 500mg four times daily for 7 days is recommended in the following infections: uncomplicated gonococcal infections (except anorectal infections in men); uncomplicated urethra;, endocervical or rectal infection caused by Chlamydia trachomatis; non-gonoccocal urethritis caused by Ureaplasma urealyticum.
Acute epididymo-orchitis caused by Chlamydia trachomatis, or Neisseria gonorroeae: 500mg four times daily for 10 days.
Primary and Secondary syphilis: 500mg four times daily for 15 days. Syphilis of more than one year's duration, (latent syphilis of uncertain or more than one year's duration, cardiovascular or late benign syphilis) except neurosyphilis, should be treated with 500mg four times daily for 30 days. Patient compliance with this regimen may be difficult so care should be taken to encourage optimal compliance. Close follow-up including laboratory tests, is recommended.
Method of Adminstration
For oral administration.
Known hypersensitivity to any of the tetracyclines or any of the other ingredients in the formulation; chronic renal/hepatic dysfunction; systemic lupus erythematosus; children under 12 years; pregnancy and breastfeeding women; patients receiving vitamin A or retinoid therapy.
Tetracycline drugs may cause permanent tooth discoloration (yellow-grey-brown), if administered during tooth development, in the last half of pregnancy and in infancy up to twelve years of age. Enamel hypoplasia has also been reported. This adverse reaction is more common during long-term use of the drug but has been observed following repeated short-term courses.
The anti-anabolic action of tetracyclines may cause an increase in BUN. While this is not a problem in those with normal renal function, in patients with significantly impaired renal function, higher serum levels of oxytetracycline may lead to azotaemia, hyperphosphataemia and acidosis.
When treating venereal disease, where co-existent syphilis is suspected, proper diagnostic procedures should be utilised. In all such cases, monthly serological tests should be made for at least four months.
The use of antibiotics may occasionally result in the overgrowth of nonsusceptible organisms including Candida. Constant observation of the patients is essential. If a resistant organism appears, the antibiotic should be discontinued and appropriate therapy instituted.
In long-term therapy, periodic laboratory evaluation of organ systems, including haematopoietic, renal and hepatic studies should be performed.
High doses of tetracyclines have been associated with a syndrome involving fatty liver degeneration and pancreatitis.
The use of tetracyclines in general is contraindicated in renal impairment due to excessive systemic accumulation and used with caution in patients with hepatic impairment or those receiving drugs which may have hepatotoxic effects; high doses should be avoided.
Care is advised when administering to patients with myasthenia gravis.
Photosensitivity reactions may occur in hypersensitive persons and such patients should be warned to avoid direct exposure to natural or artificial sunlight and to discontinue therapy at the first sign of skin discomfort.
Antacids containing aluminium, calcium, iron, magnesium or zinc may impair absorption of oxytetracycline. Allow two to three hours between doses of oxytetracycline and antacids.
Since oxytetracycline has been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require a downward adjustment of their anticoagulant dosage. Oxytetracycline may prolong the action of coumarin anticoagulants.
Antidiarrhoeal preparations such as kaolin-pectin and bismuth subsalicylate hinder absorption of tetracyclines.
Combination of tetracyclines with diuretics may be detrimental to renal function.
Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving oxytetracycline in conjunction with penicillin.
A few cases of pregnancy or breakthrough bleeding have been attributed to the concurrent use of oxytetracycline with oral contraceptives and alternative contraceptive advice should be sought where necessary.
There have been reports of nephrotoxicity (increased blood urea nitrogen and serum creatinine) and death in some cases when oxytetracycline therapy has been combined with methoxyflurane.
Oxytetracycline may increase the hypoglycaemic effects of insulin and sulphonylureas in patients with diabetes mellitus.
Benign intracranial hypertension has been reported following the concomitant use of tetracyclines and vitamin A or retinoids and therefore concurrent use is contraindicated.
Not to be used in pregnancy unless essential to the patient's welfare. Tetracyclines cross the placenta and may have toxic effects on foetal tissues, particularly on skeletal development, (see "Warnings" on tooth development).
If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the foetus. Tetracyclines are also excreted in breast milk and are therefore contraindicated in nursing mothers.
Use in newborns, infants and children: All tetracyclines form a stable calcium complex in any bone-forming tissue.
A decrease in fibula growth rate has been observed in premature infants given oral tetracycline in doses of 25mg/kg every 6 hours. This reaction was reversed when drug was discontinued.

There is no specific antidote. Gastric lavage in the first hours after ingestion along with oral administration of milk or antacids is recommended.
Oxytetracycline is a bacteriostatic antibiotic with a broad spectrum of activity against bacteria, and also some antiprotozoal properties.
The tetracyclines are incompletely and irregularly absorbed from the gastrointestinal tract.
The degree of absorption is diminished by the soluble salts of divalent and trivalent metals, with which tetracyclines form stable complexes and to a variable degree by milk or food. Plasma concentrations will depend upon the degree of absorption. Peak plasma concentrations occur about 1 to 3 hours after ingestion.
It is recommended that tetracyclines should be given before food.
A dose of 500mg every 6 hours by mouth is reported to produce steady-state plasma concentrations of 3 to 4µg per ml.
In the circulation, tetracyclines are bound to plasma proteins in varying degrees, but reported values differ considerably: from about 20 to 40% for oxytetracycline.
They are widely distributed throughout the body tissues and fluids. Small amounts appear in saliva, and the fluids of the eye and lung.
Tetracyclines appear in the milk of nursing mothers where concentrations may be 60% or more of those in the plasma. they diffuse across the placenta and appear in the foetal circulation in concentrations of about 25 to 75% of those in the maternal blood. Tetracyclines are retained at sites of new bone formation and recent calcification and in developing teeth.
The tetracyclines are excreted in the urine and in the faeces. Renal clearance is by glomerular filtration.
The tetracyclines are excreted in the bile where concentrations 5 to 25 times those in plasma can occur. Since there is some enterohepatic reabsorption complete elimination is slow. Considerable quantities occur in the faeces after administration by mouth.

NiQuitin 14 mg transdermal patches.
Each 15 cm2 contains 78 mg nicotine, equivalent to 5.1 mg/cm2 of nicotine and delivering 14 mg over 24 hours.
For excipients, see section 6.1.
Transdermal patch.
Each patch is rectangular and is comprised of an outer matt pinkish tan-coloured layer, a middle silver layer and an outer clear layer which is removed prior to use.
NiQuitin patches relieve and/or prevent craving and nicotine withdrawal symptoms associated with tobacco dependence. They are indicated to aid smokers wishing to quit or reduce prior to quitting, to assist smokers who are unwilling or unable to smoke, and as a safer alternative to smoking for smokers and those around them.
NiQuitin patches are indicated in pregnant and lactating women making a quit attempt.
If possible, when stopping smoking, NiQuitin patches should be used in conjunction with a behavioural support programme.
NiQuitin patches should be applied once a day, at the same time each day and preferably soon after waking, to a non-hairy, clean, dry skin site and worn continuously for 24 hours. The NiQuitin patch should be applied promptly on removal from its protective sachet.
Avoid applying to any skin which is broken, red or irritated. After 24 hours the used patch should be removed and a new patch applied to a fresh skin site. The patch should not be left on for longer than 24 hours. Skin sites should not be reused for at least seven days. Only one patch should be worn at a time.
Patches may be removed before going to bed if desired. However use for 24 hours is recommended to optimise the effect against morning cravings.
Concurrent behavioural support is recommended, as such programmes have been shown to be beneficial for smoking cessation.
Adults 18 years and over
Abrupt cessation of smoking:
During a quit attempt every effort should be made to stop smoking with NiQuitin patches.
NiQuitin therapy should usually begin with NiQuitin 21 mg and be reduced according to the following dosing schedule:-
|
|
|
|
|
|
|
|
Light smokers (e.g. those who smoke less than 10 cigarettes per day) are recommended to start at Step 2 (14 mg) for 6 weeks and decrease the dose to NiQuitin 7 mg for the final 2 weeks.
Patients on NiQuitin 21 mg who experience excessive side-effects (please refer to precautions), which do not resolve within a few days, should change to NiQuitin 14mg. This strength should then be continued for the remainder of the 6 week course before stepping down to NiQuitin 7mg for two weeks. If the symptoms persist the patient should be advised to seek the advice of a healthcare professional.
For optimum results, the 10 week treatment course (8 weeks for light smokers or patients who have reduced strength as above), should be completed in full. Treatment with NiQuitin patch may be continued beyond 10 weeks if needed to stay cigarette free, however, those who have quit smoking but are having difficulty discontinuing using the patches recommended to seek additional help and advice from a healthcare professional.
Further courses may be used at a later time, for NiQuitin patch users who continue or resume smoking.
Gradual Cessation:
For smokers who are unwilling or unable to quit abruptly.
The 21 mg patch can be used daily for 2-4 weeks while the user continues to smoke as needed. At the end of the 2-4 weeks the user should quit completely and continue using Step 1 21 mg patch for 6 weeks daily without smoking. Thereafter following the Step 2 and 3 directions for abrupt cessation above. Should the patient feel able to quit completely before their designated quit date they can do so.
Reduction in smoking:
For smokers who wish to cut down with no immediate plans to quit.
A patch can be used while the user continues to smoke as needed. The user should reduce the number of cigarettes smoked as far as possible and to refrain from smoking as long as possible. Users should be encouraged to stop smoking completely as soon as possible.
If users are still feeling the need to use the patches on a regular basis 6 months after the start of treatment and have still been unable to undertake a permanent quit attempt, then it is recommended to seek additional help and advice from a healthcare professional.
Temporary Abstinence
Apply a patch to control troublesome withdrawal symptoms including craving during the period when smoking is being avoided. Users should be encouraged to stop smoking completely as soon as possible.
If users are still feeling the need to use the patches on a regular basis 6 months after the start of treatment and have still been unable to undertake a permanent quit attempt, then it is recommended to seek additional help and advice from a healthcare professional.
Adolescents and children
Adolescents (12 to 17 years) should follow the schedule of treatment for abrupt cessation of smoking as given above. Where adolescents are not ready or not able to stop smoking abruptly, advice from a healthcare professional should be sought.
Safety and effectiveness in children who smoke has not been evaluated. NiQuitin is not recommended for use in children under 12 years of age.
NiQuitin is contraindicated in patients with hypersensitivity to the system, the active substance, or any of the excipients.
NiQuitin patches should not be used by non-smokers, occasional smokers or children under 12 years.
The risks associated with the use of NRT are substantially outweighed in virtually all circumstances by the well established dangers of continued smoking.
Patients hospitalised for MI, severe dysrhythmia or CVA who are considered to be haemodynamically unstable should be encouraged to stop smoking with non-pharmacological interventions. If this fails, NiQuitin patches may be considered, but as data on safety in this patient group are limited, initiation should only be under medical supervision. Once patients are discharged from hospital they can use NRT as normal.
Diabetes Mellitus: Patients with diabetes mellitus should be advised to monitor their blood sugar levels more closely than usual when NRT is initiated as catecholamines released by nicotine can affect carbohydrate metabolism.
Allergic reactions: Susceptibility to angioedema and urticaria.
Atopic or eczematous dermatitis (due to localised patch sensitivity): In the case of severe or persistent local reactions at the site of application (e.g. severe erythema, pruritus or oedema) or a generalised skin reaction (e.g. urticaria, hives or generalised skin rashes), users should be instructed to discontinue use of NiQuitin and contact their physician.
Contact sensitisation: Patients with contact sensitisation should be cautioned that a serious reaction could occur from exposure to other nicotine-containing products or smoking.
A risk benefit assessment should be made by an appropriate healthcare professional for patients with the following conditions:
• Renal and hepatic impairment: Use with caution in patients with moderate to severe hepatic impairment and/or severe renal impairment as the clearance of nicotine or its metabolites may be decreased with the potential for increased adverse effects.
• Phaeochromocytoma and uncontrolled hyperthyroidism: Use with caution in patients with uncontrolled hyperthyroidism or phaeochromocytoma as nicotine causes release of catecholamines.
Danger in small children: Doses of nicotine tolerated by adult and adolescent smokers can produce severe toxicity in small children that may be fatal. Products containing nicotine should not be left where they may be misused, handled or ingested by children. The patches should be folded in half with the adhesive side innermost and disposed of with care.
Stopping smoking: Polycyclic aromatic hydrocarbons in tobacco smoke induce the metabolism of drugs catalysed by CYP 1A2 (and possibly by CYP 1A1). When a smoker stops this may result in a slower metabolism and a consequent rise in blood levels of such drugs.
Transferred dependence: Transferred dependence is rare and is both less harmful and easier to break than smoking dependence.
Safety on handling: NiQuitin is potentially a dermal irritant and can cause contact sensitisation. Care should be taken during handling and in particular contact with the eyes and nose avoided. After handling, wash hands with water alone as soap may increase nicotine absorption.
No clinically relevant interactions between nicotine replacement therapy and other drugs has definitely been established, however nicotine may possibly enhance the haemodynamic effects of adenosine.
Pregnancy
Stopping smoking is the single most effective intervention for improving the health of both the pregnant smoker and her baby, and the earlier abstinence is achieved the better. However, if the mother cannot (or is considered unlikely to) quit without pharmacological support, NRT may be used as the risk to the foetus is lower than that expected with smoking tobacco. Stopping completely is by far the best option but NRT may be used in pregnancy as a safer alternative to smoking. Because of the potential for nicotine-free periods, intermittent dose forms are preferable, but patches may be necessary if there is significant nausea and/or vomiting. If patches are used they should, if possible, be removed at night when the foetus would not normally be exposed to nicotine.
Lactation
The relatively small amounts of nicotine found in breast milk during NRT use are less hazardous to the infant than second-hand smoke. Intermittent dose forms would minimize the amount of nicotine in breast milk and permit feeding when levels were at their lowest.

Subjects quitting smoking by any means could expect to suffer from asthenia, headache, dizziness, sleep disturbance, coughing or influenza-like illness. Certain symptoms which have been reported such as depression, irritability, nervousness, restlessness, mood lability, anxiety, drowsiness, impaired concentration and insomnia may be related to withdrawal symptoms associated with smoking cessation.
Application site reactions are the most frequent adverse reaction associated with NiQuitin. NiQuitin can cause other adverse reactions related to the pharmacological effect of nicotine or withdrawal effects related to smoking.
The following undesirable effects have been reported in clinical trials or spontaneously post-marketing.
Certain symptoms which have been reported such as depression, irritability, nervousness, restlessness, mood lability, anxiety, drowsiness, impaired concentration, insomnia and sleep disturbances may be related to withdrawal symptoms associated with smoking cessation. Subjects quitting smoking by any means could expect to suffer from asthenia, headache, dizziness, coughing or influenza-like illness.

Application site reactions, including transient rash, itching, burning, tingling, numbness, swelling, pain and urticaria are the most frequent undesirable effects of NiQuitin patch. The majority of these topical reactions are minor and resolve quickly following removal of the patch. Pain or sensation of heaviness in the limb or area around which the patch is applied (e.g. chest) may be reported.
Hypersensitivity reactions, including contact dermatitis and allergic dermatitis have also been reported. In the case of severe or persistent local reactions at the application site (e.g. severe erythema, pruritus or oedema) or a generalized skin reaction (e.g. urticaria, hives or generalised skin rashes) users should be instructed to discontinue use of NiQuitin and contact their physician.
If there is a clinically significant increase in cardiovascular or other effects attributable to nicotine, the NiQuitin dose should be reduced or discontinued.
Symptoms: The minimum lethal dose of nicotine in a non-tolerant man has been estimated to be 40 to 60mg. Symptoms of acute nicotine poisoning include nausea, salivation, abdominal pain, diarrhoea, sweating, headache, dizziness, disturbed hearing and marked weakness. In extreme cases, these symptoms may be followed by hypotension, rapid or weak or irregular pulse, breathing difficulties, prostration, circulatory collapse and terminal convulsions.
Management of an overdose: All nicotine intake should stop immediately and the patient should be treated symptomatically. Artificial respiration with oxygen should be instituted if necessary. Activated charcoal reduces the gastro-intestinal absorption of nicotine
Overdose from topical exposure: The NiQuitin system should be removed immediately if the patient shows signs of overdosage and the patient should seek immediate medical care. The skin surface may be flushed with water and dried. No soap should be used since it may increase nicotine absorption. Nicotine will continue to be delivered into the bloodstream for several hours after removal of the system because of a depot of nicotine in the skin.
Pharmacotherapeutic classification: N07BA01
(Anti-smoking agents: N07BA, Nicotine 01)
Nicotine, the chief alkaloid in tobacco products and a naturally occurring autonomic drug, is an agonist at nicotine receptors in the peripheral and central nervous system and has pronounced CNS and cardiovascular effects. Withdrawal from nicotine in addicted individuals is characterised by craving, nervousness, restlessness, irritability, mood lability, anxiety, drowsiness, sleep disturbances, impaired concentration, increased appetite, minor somatic complaints (headache, myalgia, constipation, fatigue) and weight gain. Withdrawal symptoms, such as cigarette craving, may be controlled in some individuals by steady-state plasma levels lower than those for smoking.
In clinically controlled trials, NiQuitin was shown to alleviate nicotine withdrawal symptoms as well as craving. NiQuitin reduced the severity of cravings by at least 35% at all times of day during the first two weeks of abstinence, compared to placebo (p<0.05).
Absorption
Following transdermal application, the skin rapidly absorbs nicotine released initially from the patch adhesive. The plasma concentrations of nicotine reach a plateau within 2-4 hours after initial application of NiQuitin with relatively constant plasma concentrations persisting for 24 hours or until the patch is removed. Approximately 68% of the nicotine released from the patch enters systemic circulation and the remainder of the released nicotine is lost via vaporisation from the edge of the patch.
With continuous daily application of NiQuitin (worn for 24 hours), dose-dependent steady state plasma nicotine concentrations are achieved following the second NiQuitin application and are maintained throughout the day. These steady state maximum concentrations are approximately 30% higher than those following a single application of NiQuitin.
Plasma concentrations of nicotine are proportional to dose for the three dosage forms of NiQuitin. The mean plasma steady state concentrations of nicotine are approximately 17 ng/ml for the 21 mg/day patch, 12 ng/ml for the 14 mg /day patch and 6 ng/ml for the 7 mg/day patch. For comparison, half-hourly smoking of cigarettes produces average plasma concentrations of approximately 44 ng/ml.
The pronounced early peak in nicotine blood levels seen with inhalation of cigarette smoke is not observed with NiQuitin.
Distribution
Following removal of NiQuitin, plasma nicotine concentrations decline with an apparent mean half-life of 3 hours, compared with 2 hours for IV administration due to continued absorption of nicotine from the skin depot. If NiQuitin is removed most non-smoking patients will have non-detectable nicotine concentrations in 10 to 12 hours.
A dose of radiolabelled nicotine given intravenously showed a distribution of radioactivity corresponding to the blood supply with no organ selectively taking up nicotine. The volume of distribution of nicotine is approximately 2.5 l/kg.
Metabolism
The major elimination organ is the liver and average plasma clearance is about 1.2 l/min; the kidney and the lung also metabolise nicotine. More than 20 metabolites of nicotine have been identified, all of which are believed to be pharmacologically inactive. The principal metabolites are cotinine and trans
Excretion
Both nicotine and its metabolites are excreted through the kidneys and about 10% of nicotine is excreted unchanged in the urine. As much as 30% may be excreted in the urine with maximum flow rates and extreme urine acidification (pH
There were no differences in nicotine kinetics between men and women using NiQuitin. Obese men using NiQuitin had significantly lower AUC and Cmax values compared with normal weight men. Linear regression of AUC vs total body weight showed the expected inverse relationship (AUC decreases as weight increases). Nicotine kinetics were similar for all sites of application on the upper body and upper outer arm.
The general toxicity of nicotine is well known and taken into account in the recommended posology. Nicotine was not mutagenic in appropriate assays. The results of carcinogenicity assays did not provide any clear evidence of a tumorigenic effect of nicotine. In studies in pregnant animals, nicotine showed maternal toxicity, and consequential mild fetal toxicity. Additional effects included pre- and postnatal growth retardation and delays and changes in postnatal CNS development.
Effects were only noted following exposure to nicotine at levels in excess of those which will result from recommended use of NiQuitin. Effects on fertility have not been established.
Comparison of the systemic exposure necessary to elicit these adverse responses from preclinical test systems with that associated with the recommended use of NiQuitin indicate that the potential risk is low and outweighed by the demonstrable benefit of nicotine therapy in smoking cessation. However, NiQuitin should only be used by pregnant women on medical advice if other forms of treatment have failed.

[Posted 08/16/2007] FDA approved updated labeling to include pharmacogenomics information to the CLINICAL PHARMACOLOGY, PRECAUTIONS, and DOSAGE AND ADMINISTRATION sections of the prescribing information for the widely used blood-thinning drug, warfarin (Coumadin). This new information explains that people’s genetic makeup may influence how they respond to the drug. Specifically, people with variations in two genes may need lower warfarin doses than people without these genetic variations. The two genes are called CYP2C9 and VKORC1. The CYP2C9 gene is involved in the breakdown (metabolism) of warfarin and the VKORC1 gene helps regulate the ability of warfarin to prevent blood from clotting.
The dosage and administration of warfarin must be individualized for each patient according to the particular patient’s prothrombin time (PT) / International Normalized Ratio (INR) response to the drug. The specific dose recommendations are described in the warfarin product labeling, along with the new information regarding the impact of genetic information upon the initial dose and the response to warfarin. Ongoing warfarin therapy should be guided by continued INR monitoring. For more information visit the FDA website at: .
[Posted 10/06/2006] FDA and Bristol-Myers Squibb notified pharmacists and physicians of revisions to the labeling for warfarin (Coumadin), to include a new patient Medication Guide as well as a reorganization and highlighting of the current safety information to better inform providers and patients.
The FDA regulation 21CFR 208 requires a Medication Guide to be provided with each prescription that is dispensed for products that FDA determines pose a serious and significant public health concern. Information about all currently approved Medication Guides is available at: . For more information visit the FDA website at: , and .

Adjusted-dose warfarin also recommended by some clinicians for prevention of thromboembolic events in patients with mitral valve regurgitation and concomitant atrial fibrillation or a history of systemic embolism.341 371
Long-term antithrombotic therapy generally not recommended in patients with mitral annular calcification who lack a history of thromboembolism or atrial fibrillation.340 371 c However, ACCP suggests that long-term warfarin therapy be given to patients with mitral annular calcification complicated by systemic embolism not documented to be calcific embolism or in those who have atrial fibrillation.340 371 c
Generally should not initiate anticoagulant therapy in patients with uncomplicated infective endocarditis involving a native valve because of the risk of hemorrhage and lack of documented efficacy.340 371
Oral anticoagulant therapy recommended in patients undergoing mitral valvuloplasty beginning 3 weeks prior to the procedure and continuing for 4 weeks following the procedure.c
Generally should not initiate long-term anticoagulant therapy in patients with aortic arch valve disease unless warranted by a coexisting condition.371 c However, ACCP states that patients with mobile aortic atheromas and aortic plaques >4 mm (as measured by transesophageal echocardiography) should receive long-term anticoagulation with warfarin.371 c
Follow-up anticoagulation after unfractionated heparin or an LMW heparin for prevention of thromboembolic complications associated with heart valve replacement.211 341 347 370 433 c
Risk of systemic embolism is higher with prosthetic mechanical than with bioprosthetic heart valves, higher with first-generation mechanical (e.g., caged ball, caged disk) valves than with newer mechanical (e.g., bileaflet, Medtronic Hall tilting disk) heart valves, higher with more than one prosthetic valve, and higher with prosthetic mitral than with aortic valves; risk also increases in the presence of atrial fibrillation.341 342 343 347 370 431 433 Lifelong prophylaxis required in all patients with mechanical heart valves because of associated high risk of thromboembolism.341 347 370

Short-term prophylaxis in patients with a bioprosthetic valve and evidence of a left atrial thrombus.433
Long-term prophylaxis in patients with a bioprosthetic valve and other risk factors (e.g., atrial fibrillation, prior thromboembolism, left ventricular dysfunction, hypercoagulable states).341 347 370 433
Generally should not initiate anticoagulant therapy in patients with uncomplicated infective endocarditis involving a bioprosthetic heart valve because of the risk of hemorrhage and lack of documented efficacy.340 371 433 However, ACCP states that patients with mechanical prosthetic valves receiving long-term anticoagulation who develop infective endocarditis generally should remain on anticoagulant therapy unless there are specific contraindications, keeping in mind the substantial risk of intracranial hemorrhage.340 371 c
Treatment of “breakthrough” thromboembolic events in patients with prosthetic heart valves receiving thromboprophylaxis.211 341 433 c Combination therapy with aspirin recommended in patients with breakthrough embolic event despite warfarin therapy.433 341 370 433 c

Secondary prevention in patients with TIAs† or mild ischemic stroke and concurrent atrial fibrillation, provided no contraindications to therapy exist.335 338 349 352 373 432 434
Used in conjunction with aspirin for prevention of recurrent stroke in patients at high risk for recurring cerebral embolism from other cardiac sources (e.g., mechanical prosthetic heart valves, recent MI, left ventricular thrombus, dilated cardiomyopathies, marantic endocarditis, extensive wall-motion abnormalities).335 338 349 352 432 Follow-up anticoagulation after heparin or an LMW heparin in patients with recent MI and acute ischemic stroke and cardiac sources of embolism.432
Has been used as follow-up anticoagulation after heparin therapy for the prevention of embolism in paralyzed or immobile patients with progressive stroke† (when the suspected mechanism is thromboembolic) or stroke-in-evolution†.212 373 However, use of heparin or an LMW heparin not recommended by ACCP in patients with a stroke-in-evolution because of lack of conclusive data on efficacy and safety.434
Short-term (3–6 months) follow-up anticoagulation with warfarin or an LMW heparin after heparin or an LMW heparin in children with arterial ischemic stroke from cardiac sources† or vascular dissection.446 May initiate aspirin following completion of anticoagulation.446
Long-term antithrombotic therapy generally not recommended in asymptomatic patients with a patent foramen ovale or atrial septal aneurysm unless such patients have unexplained system embolism or TIAs and demonstrable venous thrombosis or pulmonary embolism.340 371 Treatment of suspected DVT in patients with cryptogenic stroke and patent foramen ovale†.434 ACCP suggests use of antiplatelet agents over warfarin in patients with cryptogenic stroke and patent foramen ovale without DVT.434
ACCP suggests either oral anticoagulation or antiplatelet agents for secondary prophylaxis in patients with cryptogenic stroke and mobile arch thrombi†.434
Oral anticoagulation (3–6 months) recommended by ACCP as follow-up to unfractionated heparin or an LMW heparin in patients with acute cerebral venous sinus thrombosis†.
Prevention of saphenous vein or internal mammary artery graft occlusion following CABG†.376 448 ACCP recommends use in combination with aspirin when other coexisting conditions (e.g., heart valve replacement) warrant such therapy.376 448
Has been used short-term for prevention of stent thrombosis after stent placement† or long-term (1–6 months) for prevention of restenosis following PCI†.447 Since warfarin has no apparent advantages over antiplatelet therapy, not routinely recommended by ACCP after PCI if no other indications for anticoagulation exist.447
Has been used in selected patients with peripheral arterial occlusive disease†, but ACCP currently recommends against use of anticoagulants for intermittent claudication.377 449
ACCP recommends long-term follow-up oral anticoagulation after initial heparin treatment in patients undergoing embolectomy†.377 449
ACCP recommends long-term oral anticoagulation in postsurgical patients following pulmonary thromboendarterectomy† and in patients ineligible for such a procedure.427
Prevention (combined with aspirin therapy) of embolism in selected (high risk for graft thrombosis and limb loss) patients after infrainguinal femoropopliteal or distal vein bypass†.377 449
Has been administered as follow-up treatment of heparin-induced thrombocytopenia† when substantial recovery has occurred (i.e., platelet counts ≥ 100,000–150,000/mm3 and are stable) after therapy with a direct thrombin inhibitor (e.g., lepirudin, bivalirudin, argatroban).392 441 442 443 444 Overlap therapy for approximately 5 days until an adequate response to warfarin is obtained.387 392 393
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
Carefully individualize dosage based on clinical and laboratory findings (i.e., determination of INR and/or PT ratios).211 Adjust dosage in small increments and carefully monitor patient response.a Determine optimum duration of therapy by the condition being treated and its severity.a
Determine PT prior to and 24 hours after initiation of therapy.211 a 426 Determine PT daily until the PT/INR is in the therapeutic range.211 Intervals between subsequent PT determinations based on clinician’s judgment and patient’s response.211 Determine PT/INR generally every 1–4 weeks after a stable dosage has been determined.211 426
Determine PT when different warfarin preparations (e.g., proprietary versus generic) are interchanged.211 a Determine PT when concomitant drug therapy is added, discontinued, or taken irregularly.211 a
Dosage does not vary with the route of administration.211
Administration of large loading doses (i.e., >20 mg) not recommended.211 426 Possible increased risk of hemorrhage or necrosis.211 (See Hemorrhage under Cautions.)
For follow-up therapy after heparin, the manufacturer recommends that therapy with heparin and warfarin be used concurrently for at least 4–5 days or until the desired PT/INR has been achieved.211 Some clinicians recommend that unfractionated heparin or an LMW heparin be used concurrently with warfarin for about 5–7 days or until the desired INR has been achieved for 2 consecutive days.427
Increased risk of thrombosis or rebound thromboembolism has been suggested following abrupt discontinuance of warfarin therapy; some manufacturers recommend gradually decreasing dosage (e.g., over 3–4 weeks) when withdrawing therapy.a
For follow-up therapy after most direct thrombin inhibitors, overlap therapy with direct thrombin inhibitors for ≥5 days until desired INR has been achieved for 2 consecutive days.441 443
Combined therapy with argatroban and warfarin prolongs the PT and INR beyond that produced by warfarin alone.392 441 Determine PT and INR daily during concurrent argatroban and warfarin therapy.392 Continue to monitor the effects of argatroban using aPTT during conversion to warfarin.392
For an argatroban infusion rate ≤2 mcg/kg per minute, discontinue argatroban therapy when INR on combined therapy >4.392 Avoid overshooting target INR, as supratherapeutic INRs during concomitant therapy with direct thrombin inhibitors and warfarin have been associated with necrosis or gangrene of the skin or limbs.441 442 444
Determine INR 4–6 hours after discontinuance of argatroban infusion during warfarin monotherapy.392 If INR is below the desired therapeutic range, resume argatroban infusion.392 Repeat attempts to discontinue argatroban daily and until INR (4–6 hours after discontinuance of argatroban) on warfarin alone is in therapeutic range.392
For argatroban infusion rates >2 mcg/kg per minute, reduce infusion rate temporarily to 2 mcg/kg per minute, and reinstitute the procedure just described for conversion to oral therapy.392 Repeat INR determination 4–6 hours after reduction of the argatroban infusion and reinstitute procedure just described for conversion to oral therapy.392
