Medicine Description marevan 1mg
Marevan 1mg tablets is a medication that acts as an anticoagulant, specifically functioning as a vitamin K antagonist. It interferes with the synthesis of vitamin K-dependent clotting factors in the liver, which include Factors II (prothrombin), VII, IX, and X. By inhibiting the enzyme vitamin K epoxide reductase, Marevan reduces the availability of vitamin K. This leads to a decrease in the production of functional clotting factors, ultimately preventing the formation of blood clots and reducing the risk of thromboembolic events. The anticoagulant effect of Marevan can be monitored using prothrombin time, particularly expressed as the International Normalized Ratio (INR), to ensure optimal therapeutic levels and minimize the risk of bleeding complications.
Indications and Uses of Marevan 1mg tablets
- Prevention of venous thromboembolism in patients with deep vein thrombosis (DVT).
- Prevention of pulmonary embolism (PE), particularly in high-risk patients.
- Management and secondary prevention of thromboembolic events in patients with atrial fibrillation.
- Prophylaxis in patients with prosthetic heart valves to prevent thrombus formation.
- Long-term treatment of patients with a history of thromboembolic disorders.
Side Effects of Marevan 1mg tablets
- Increased risk of bleeding, including gastrointestinal bleeding.
- Hemorrhagic complications, such as intracranial hemorrhage.
- Nausea or vomiting.
- Skin reactions, including rashes or necrosis.
- Allergic reactions, which may present as hives or swelling.
Storage and Handling
Marevan 1mg tablets should be stored at room temperature, away from moisture and heat. It is important to keep the medication in its original container, tightly closed, and out of reach of children.
Patient Advice and Precautions
Patients taking Marevan should have regular INR monitoring to adjust the dosage as needed. It is crucial to inform healthcare providers about all medications being taken, including over-the-counter drugs and supplements, as many can interact with warfarin. Patients should be counseled on the signs of bleeding and instructed to seek medical help if they experience unexpected bruising, prolonged bleeding, or signs of internal bleeding. Dietary changes, particularly in vitamin K intake, should be discussed with healthcare providers to maintain stable anticoagulation levels.
