Overview
Apo-Warfarin 5mg Tablet is a prescription-only medicine (POM) that contains Warfarin 5mg (as warfarin sodium). It is supplied as a tablet and is dispensed in Malaysia only against a valid prescription issued by a registered doctor.
Under Malaysian rules for prescription medicines, this page carries product, safety and handling information only. Your doctor or pharmacist will explain whether this medicine is suitable for you, the dose you should take, and how long you should take it.
On DoctorOnCall, Apo-Warfarin 5mg Tablet is reviewed by a licensed doctor through an online consultation and dispensed by a registered pharmacist before delivery. Always follow the instructions on your prescription label and the package insert supplied with the product, and do not share this medicine with anyone else.
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.
Shelf Life
Use this product before the expiry date stated on the packaging. Do not use the medicine if the expiry date has passed.
Storage Instructions
Store below 30°C in a dry place, away from direct sunlight and out of reach of children.
Side Effects
- Bleeding or bruising easily
- Nosebleeds or bleeding gums
- Nausea or loss of appetite
- Hair thinning
- Purple toes syndrome (rare)
- Fatigue
- Abdominal cramps
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

Why is there no information here about what Apo-Warfarin 5mg Tablet is for?
Malaysian rules for prescription medicines limit public product pages to product, safety and handling information. Your doctor decides whether this medicine is appropriate for you and will explain it during your consultation, and your pharmacist can answer further questions when the medicine is dispensed.

What should I do if I miss a dose?
Take it as soon as you remember, unless your next dose is nearly due. In that case skip the missed dose and carry on with your usual schedule. Never take two doses together to make up for a missed one. If you miss doses often, tell your doctor or pharmacist.

Can I stop taking Apo-Warfarin 5mg Tablet on my own?
No. Speak to your doctor before stopping, pausing or changing the dose, even if you feel well or think you no longer need the medicine.
How do I get a prescription for Apo-Warfarin 5mg Tablet?
Customers in Malaysia can complete an online consultation with a DoctorOnCall doctor, who decides whether a prescription is appropriate, or upload a valid prescription already issued by their own doctor.
Orders going to Singapore are dispatched from Malaysia as an international delivery, so you need to hold a valid prescription or doctor’s letter for the medicine. Check the consultation and prescription upload options shown at checkout for your delivery address before placing the order.
How long will delivery take?
Within Malaysia, standard delivery takes 3 to 5 working days. Same-day delivery is available in the Klang Valley for orders placed before 12pm; orders placed after 12pm arrive by the end of the next day.
Orders to Singapore are sent as international deliveries and take 5 to 9 working days. A lump-sum shipping and handling fee applies to every overseas delivery and is shown at checkout.
What payment methods can I use?
Customers in Malaysia can pay by FPX online banking, credit or debit card (Visa and Mastercard), and supported e-wallets including Touch ‘n Go eWallet, GrabPay and ShopeePay.
FPX and local e-wallets are tied to Malaysian bank and wallet accounts, so if your delivery address is in Singapore, use the payment options displayed at checkout for that address rather than assuming the same list applies.
Can Apo-Warfarin 5mg Tablet be delivered to Singapore?
Yes. DoctorOnCall ships to Singapore as an international order dispatched from Malaysia, arriving in 5 to 9 working days with a lump-sum shipping and handling fee.
Singapore’s Health Sciences Authority (HSA) allows personal imports of up to three months’ supply of a medicine for your own use or an immediate family member’s, as long as it contains no controlled drugs, psychotropic substances or prohibited items. Keep the product in its original labelled packaging and keep a copy of your prescription or doctor’s letter with it. Quantities above three months’ supply, and medicines containing controlled substances, require prior HSA approval.
Is Apo-Warfarin 5mg Tablet registered with the authorities?
Products listed on DoctorOnCall are registered with Malaysia’s Ministry of Health for supply in Malaysia, and each pack carries its MAL registration number.
An order delivered to Singapore arrives as a personal import of a Malaysia-registered product; HSA product registration is not required for personal-use quantities, but it is also not the same as a product registered for sale in Singapore. If you need a locally registered Singapore product, buy it from a pharmacy in Singapore.
Who do I contact if there is a problem with my order?
DoctorOnCall’s customer care team handles order, delivery and product queries through the contact channels on the site, including WhatsApp and the online help centre.
For deliveries to Singapore, allow more time before chasing an order than you would for a local Malaysian delivery, as the parcel passes through customs clearance and tracking updates can appear later in the journey.
