Overview
Apo-Warfarin 5mg Tablet contains warfarin 5mg, a vitamin K antagonist oral anticoagulant used to prevent and treat blood clots such as deep vein thrombosis and pulmonary embolism, to prevent stroke in atrial fibrillation, and after certain mechanical heart valve replacements. It must only be used under close medical supervision with regular blood test monitoring.
Warfarin works by interfering with the liver’s ability to use vitamin K to produce certain clotting factors, which reduces the blood’s tendency to clot. Its effect takes several days to develop fully and several days to wear off after stopping.
How it Works
Warfarin inhibits vitamin K epoxide reductase, an enzyme the liver needs to recycle vitamin K into its active form. Without active vitamin K, the liver cannot fully activate clotting factors II, VII, IX, and X, reducing the blood’s ability to form clots.
Directions for Use
Take Apo-Warfarin 5mg Tablet at the same time each day, usually in the evening, with or without food. Try to keep your day-to-day intake of vitamin K-rich foods (such as leafy green vegetables) reasonably consistent rather than avoiding them altogether, as sudden changes can affect how the medicine works. Never skip or double a dose, and attend every scheduled INR blood test.
Dosage
The dose of Apo-Warfarin 5mg Tablet is highly individualised and based on regular blood tests (INR – International Normalised Ratio) that measure how quickly your blood clots. Never adjust your dose yourself – your doctor will determine and adjust your dose to keep your INR within your specific target range.

Contraindications
- Known hypersensitivity to warfarin
- Active, clinically significant bleeding
- Pregnancy (warfarin can cause serious birth defects, especially in the first trimester; use in pregnancy is only ever considered by a specialist in specific situations such as a mechanical heart valve)
- Recent major surgery or a high bleeding-risk procedure
- Severe uncontrolled hypertension or conditions with a high bleeding risk, such as active peptic ulcer disease
Drug / Food Interactions
- Many antibiotics (e.g. metronidazole, fluoroquinolones, macrolides) and antifungals (e.g. fluconazole) can significantly increase your INR and bleeding risk
- NSAIDs and aspirin increase the risk of bleeding when combined with warfarin
- Sudden large changes in intake of vitamin K-rich foods (leafy greens such as kale, spinach, broccoli) can alter warfarin’s effect – keep your intake consistent rather than avoiding these foods
- Many herbal supplements (e.g. St John’s Wort, ginkgo) and alcohol can also affect your INR unpredictably – always check with your doctor or pharmacist before starting anything new
Quick Tips
- Attend every scheduled INR blood test without fail
- Never change your dose on your own – always follow your doctor’s instructions after each INR result
- Keep your vitamin K intake (leafy greens) roughly consistent rather than cutting it out suddenly
- Tell every healthcare provider, including your dentist, that you are taking warfarin before any procedure, and carry an anticoagulant alert card
Frequently Asked Questions
What is Apo-Warfarin 5mg Tablet used for?
Apo-Warfarin 5mg Tablet is an anticoagulant (“blood thinner”) used to prevent and treat blood clots, and to reduce the risk of stroke in certain heart conditions. Your doctor will confirm the specific reason it has been prescribed for you.
Why do I need frequent blood tests while on this medicine?
Warfarin’s effect varies between individuals and can be influenced by diet, other medicines, and illness, so regular INR blood tests are needed to make sure your blood is neither too thin (bleeding risk) nor too thick (clotting risk), and to guide any dose adjustments.
Can I still eat vegetables like spinach and broccoli while on warfarin?
Yes. You do not need to avoid vitamin K-rich foods – in fact, suddenly stopping them can also affect your INR. The key is to keep your intake fairly consistent from week to week rather than changing it suddenly.
Can I take painkillers like ibuprofen while on this medicine?
It is best to avoid NSAIDs such as ibuprofen unless your doctor has specifically approved it, as they increase the risk of bleeding when combined with warfarin. Paracetamol is generally a safer option for pain relief, but check with your pharmacist or doctor first.
What should I do if I miss a dose of Apo-Warfarin 5mg Tablet?
Contact your doctor or pharmacist for specific advice, as this can depend on your usual dosing schedule and how late the dose is. Do not simply double your next dose without guidance, as this can significantly increase your bleeding risk.
