Marevan Forte (Warfarin Sodium)

Warfarin blocks the enzyme vitamin K epoxide reductase, which is needed to recycle vitamin K into its active form. Without active vitamin K, the liver produces lower amounts of clotting factors II, VII, IX, and X. This results in a prolonged clotting time and helps prevent the formation of harmful blood clots.

The dose of Marevan Forte is individualized. A qualified prescriber determines the starting amount and any adjustments based on the patient’s INR values, clinical condition, age, weight, and other medications. Patients should follow the prescribing clinician’s instructions and attend regular monitoring appointments.

Warfarin is classified as pregnancy Category X because it can cross the placenta and cause fetal bleeding, malformations, or death. It is therefore contraindicated during pregnancy. Breastfeeding is also not recommended, as warfarin is excreted in milk and may affect the infant’s coagulation.

To request Marevan Forte, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain needs), and required import documentation.

Marevan Forte (warfarin) is a vitamin K antagonist, whereas direct oral anticoagulants (DOACs) such as apixaban or rivaroxaban inhibit specific clotting factors directly. Warfarin requires regular INR monitoring and has many drug‑food interactions, but it is inexpensive and has a well‑established reversal protocol with vitamin K. DOACs have more predictable pharmacokinetics and fewer monitoring requirements but may be costlier.

Store Marevan Forte at room temperature, below 25 °C, in its original packaging to protect it from moisture and light. Keep the container tightly closed and out of reach of children. Do not store in bathrooms or near heat sources, and discard any tablets that appear discolored or damaged.

Marevan Forte is taken orally, usually once daily, with or without food as directed by the prescriber. The tablet should be swallowed whole with a full glass of water. Patients must adhere to the dosing schedule and attend regular INR checks to ensure therapeutic effectiveness.

The most critical risks include severe or uncontrolled bleeding (such as gastrointestinal hemorrhage, intracranial bleed, or hematuria), 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 any signs of skin discoloration or pain.

Marevan Forte should be avoided in patients with active major bleeding, recent intracranial hemorrhage, severe liver disease, uncontrolled hypertension, or known hypersensitivity to warfarin. It is also contraindicated during pregnancy (Category X) and generally not recommended for breastfeeding mothers without specialist advice.
