Warfarin 3 mg Tablets – 28

Warfarin 3 mg is an oral anticoagulant widely used to prevent and manage blood clots. It contains Warfarin, a vitamin K antagonist that reduces the blood’s ability to clot. Warfarin is commonly prescribed for patients at risk of thromboembolic events, particularly those with cardiac conditions or a history of clot formation.

Active Ingredient and Composition

• Active Ingredient: Warfarin

• Strength: 3 mg per tablet

• Dosage Form: Oral tablets

• Pack Size: 28 tablets

Drug Class

• Pharmacological Class: Vitamin K antagonist

Uses and Medical Indications of Warfarin

Warfarin 3 mg is indicated for:

• Treatment and prevention of blood clots (deep vein thrombosis and pulmonary embolism)

• Atrial fibrillation-related stroke prevention

• Patients with mechanical heart valves

• Prevention of recurrent myocardial infarction

• Prevention of ischemic stroke

It is essential for long-term anticoagulation in high-risk patients.

How Warfarin Works

Warfarin works by inhibiting vitamin K–dependent clotting factors (II, VII, IX, and X) in the liver. This reduces the blood’s ability to form clots, helping prevent clot growth and new clot formation.

Dosage and Administration of Warfarin

• Dose is individualized based on INR (International Normalized Ratio)

• Typically taken once daily at the same time

• Regular blood monitoring (INR testing) is essential

Important:

• Do not change dose without medical advice

• Maintain consistent dietary vitamin K intake

Possible Side Effects of Warfarin

Common or notable side effects include:

• Nosebleeds

• Unusual bruising

• Bleeding gums

• Headache or dizziness

• Abdominal discomfort

Serious warning signs:

• Black or bloody stools

• Blood in urine

• Vision changes

• Prolonged or heavy bleeding

Contraindications

Do not use Warfarin if you have:

• Active bleeding disorders

• Recent major surgery with bleeding risk

• Known hypersensitivity to warfarin

• Pregnancy (high risk of fetal harm)

Drug Interactions

Warfarin has numerous drug interactions, including:

• Antibiotics and antifungals

• NSAIDs (e.g., ibuprofen)

• Aspirin and antiplatelet drugs

• Herbal supplements (e.g., St. John’s Wort)

These interactions may increase or decrease anticoagulant effect.

Warnings and Precautions

• Requires frequent INR monitoring

• Maintain consistent diet (avoid sudden changes in vitamin K intake)

• Increased risk of bleeding—use caution in daily activities

• Inform healthcare providers before any surgery or dental procedure

Use During Pregnancy and Breastfeeding

• Contraindicated in pregnancy due to risk of fetal harm

• May be used cautiously during breastfeeding under medical supervision

Use for Children

• Used only under specialist supervision with careful monitoring

Drug Alternatives

Alternative anticoagulants include:

• Direct oral anticoagulants (DOACs) such as rivaroxaban and apixaban

• Heparin and low molecular weight heparins

Comparison With Similar Drugs

Compared with DOACs:

• Warfarin requires regular INR monitoring

• More dietary and drug interactions

• Preferred in certain conditions (e.g., mechanical heart valves)

Safe Usage Tips

• Take medication at the same time daily

• Monitor INR regularly

• Avoid activities with high bleeding risk

• Use a soft toothbrush and electric razor

• Inform your doctor about all medications and supplements

Frequently Asked Questions (FAQ)

Does Warfarin dissolve blood clots?
No, it prevents clot growth and formation. The body naturally breaks down existing clots.

When does Warfarin start working?
It begins affecting clotting within 24–72 hours, with full effect in 3–5 days.

When should I seek medical help?
If you experience unusual bleeding, black stools, or severe symptoms.

Do blood clots disappear with treatment?
Yes, over time, the body dissolves them while anticoagulants prevent new ones.

Conclusion

Warfarin 3 mg is a critical anticoagulant for preventing and managing blood clots in high-risk patients. With proper monitoring and adherence to medical guidance, Warfarin plays a vital role in reducing life-threatening thromboembolic complications.
