Marfarin (Warfarin Sodium)

Warfarin Sodium blocks vitamin K epoxide reductase, an enzyme needed to recycle vitamin K. This reduces the production of vitamin K‑dependent clotting factors II, VII, IX, and X, thereby decreasing the blood’s ability to form clots.

The dose of Marfarin is individualized by a healthcare professional. Dosing is guided by regular monitoring of the International Normalized Ratio (INR) to keep anticoagulation within a therapeutic range specific to the patient’s condition.

Warfarin, the active ingredient in Marfarin, is classified as pregnancy category X because it can cause fetal harm and is contraindicated during pregnancy. Use while breastfeeding is generally not recommended unless the benefit outweighs the risk and is decided by a physician.

Marfarin (warfarin) is a vitamin K antagonist that requires INR monitoring and has many dietary and drug interactions. Direct oral anticoagulants (DOACs) such as apixaban or rivaroxaban have more predictable pharmacokinetics and do not need routine monitoring, but warfarin remains useful for patients with mechanical heart valves or severe renal impairment.

Store Marfarin tablets at ambient temperature, below 25 °C, in the original container to protect from moisture and light. Keep out of reach of children and do not use if the packaging is damaged.

Marfarin is taken orally as a tablet, usually once daily. It can be taken with or without food, but consistency with meals helps maintain stable absorption. Patients should follow the prescribing physician’s instructions regarding timing and any required dietary considerations.

The most serious risks include severe or life‑threatening bleeding (such as intracranial or gastrointestinal hemorrhage), skin necrosis, and rare allergic reactions. Patients should seek immediate medical attention if they notice unusual bruising, blood in urine or stool, severe headache, or skin discoloration.

Marfarin should not be used by individuals who are pregnant, have active major bleeding, recent major surgery, uncontrolled hypertension, severe liver disease, or known hypersensitivity to warfarin. It is also contraindicated in patients with certain clotting factor deficiencies unless specifically directed by a specialist.
