COUMADIN-3MG

# Warfarin 3 mg ## Short Description Warfarin 3 mg is an **oral anticoagulant (blood thinner)** used to help prevent and treat harmful blood clots. It is commonly prescribed for conditions such as certain types of atrial fibrillation, deep vein thrombosis (DVT), pulmonary embolism (PE), and for some patients with artificial heart valves. Warfarin has a **narrow therapeutic range**, so regular blood testing, usually an **INR test**, is essential to ensure the dose is safe and effective. ## Key Benefits * Helps prevent harmful blood clots * Helps treat existing blood-clot conditions * Reduces the risk of stroke in certain patients with atrial fibrillation * Helps prevent clot-related complications after certain heart-valve procedures * Can be used for long-term anticoagulation when medically indicated * Allows anticoagulation to be adjusted using INR monitoring ## Uses / Indications Warfarin may be prescribed for: * Prevention of stroke and systemic embolism in selected patients with atrial fibrillation * Treatment of deep vein thrombosis (DVT) * Treatment of pulmonary embolism (PE) * Prevention of recurrent DVT or PE * Prevention of thromboembolic complications associated with certain mechanical heart valves * Other clotting conditions when specifically prescribed Warfarin does **not dissolve an existing clot immediately**. It reduces the body's ability to form new clots and prevents existing clots from growing while the body gradually breaks them down. ## How It Works Warfarin is a **vitamin K antagonist anticoagulant**. It blocks vitamin K-dependent production of several clotting factors in the liver, including factors II, VII, IX and X. **Warfarin → reduces vitamin K-dependent clotting factors → slows blood clot formation → lowers the risk of harmful clots** Because its effect varies significantly between individuals, the dose is adjusted according to **INR blood-test results**. ## Dosage & Administration The correct warfarin dose is **individualized** and should only be determined by a healthcare professional. * Take exactly as prescribed * Take warfarin at the same time each day * Swallow with water * Do not change the dose yourself * Do not stop warfarin suddenly unless instructed by your doctor * Attend all scheduled INR blood tests * Keep your vitamin K intake reasonably consistent from day to day * Tell your healthcare professional before starting or stopping any medicine or supplement **Warfarin 3 mg does not mean that 3 mg is the correct daily dose for every patient.** Your prescribed dose may change based on your INR and medical condition. ### Missed Dose If you remember the missed dose on the same day, follow your healthcare professional's instructions. If you remember the next day, **do not double the dose**. Contact your anticoagulation clinic or healthcare professional if you are unsure what to do. ## Side Effects The most important side effect of warfarin is **bleeding**. Possible side effects include: * Easy bruising * Nosebleeds * Bleeding gums * Prolonged bleeding from cuts * Heavy menstrual bleeding * Blood in urine * Blood in stool * Unusual or persistent bleeding ### Serious Side Effects Seek urgent medical attention for: * Vomiting blood * Coughing up blood * Black or bloody stools * Severe or persistent headache * Sudden weakness, numbness or difficulty speaking * Severe abdominal pain * Heavy or uncontrolled bleeding * Large unexplained bruises * A significant head injury while taking warfarin Rarely, warfarin can cause serious tissue or skin complications. ## Precautions & Warnings * Warfarin can cause **serious or fatal bleeding** * Regular INR monitoring is essential * Do not change or skip doses without medical advice * Tell every healthcare professional that you take warfarin * Inform your doctor before surgery, dental procedures or invasive procedures * Avoid activities with a high risk of serious injury when possible * Seek medical attention after a significant head injury * Maintain a consistent intake of vitamin K-containing foods rather than suddenly changing your diet * Avoid starting herbal products or supplements without professional advice * Tell your doctor if you have liver disease or kidney disease * Tell your doctor if you have a history of gastrointestinal bleeding * Inform your doctor if you have uncontrolled high blood pressure * Tell your doctor if you are pregnant or planning pregnancy ### Pregnancy Warning Warfarin can cause serious harm to a developing fetus and is **generally contraindicated during pregnancy**, although specialist circumstances exist.

Warfarin is commonly called a **blood thinner**, although it does not literally thin the blood. It reduces the blood's ability to form clots. ### How does Warfarin work? Warfarin blocks vitamin K-dependent clotting-factor production, reducing the blood's ability to form harmful clots. ### Why do I need an INR test while taking Warfarin? The INR test measures how strongly warfarin is affecting your blood clotting. Regular testing helps your healthcare professional adjust the dose and reduce the risk of bleeding or inadequate anticoagulation. ### Is Warfarin 3 mg a standard dose? No. Warfarin dosing is individualized. Some people may need 3 mg daily, while others require a different dose.
