Overview
Orfarin 5mg Tablet is a prescription-only medicine (POM) presented as a tablet, with Warfarin sodium 5mg as its active ingredient content.
This page is limited to product, safety and handling information, in line with Malaysian rules on prescription medicine information for the public. Your prescriber or pharmacist is the right source for anything beyond that, together with the leaflet inside the pack.
Through DoctorOnCall, this product is supplied after an online consultation with a licensed doctor and a valid prescription, and it is checked by a registered pharmacist before dispensing. Take it exactly as prescribed, and speak to your doctor before stopping, changing the dose, or starting any other medicine alongside it.
Directions for Use
Take Orfarin 5mg Tablet at the same time each day, usually in the evening, so that any dose adjustment based on a same-day INR result can be applied promptly. Swallow the tablet with water, and try to maintain a fairly consistent daily intake of vitamin K-containing foods (such as leafy green vegetables) rather than making sudden major changes to your diet.
Dosage
The dose of Orfarin 5mg Tablet is individualised for each patient and adjusted by your doctor based on regular blood tests measuring your International Normalised Ratio (INR), which reflects how quickly your blood clots. Never change your dose or stop this medicine without your doctor’s advice, as both under-treatment and over-treatment carry serious risks.
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 or any ingredient in this product
- Active or recent significant bleeding, or a high risk of bleeding
- Pregnancy (warfarin can cause serious birth defects and fetal bleeding)
- Severe uncontrolled hypertension or recent major surgery
- Severe liver or kidney impairment (increases bleeding risk)
Drug / Food Interactions
- Aspirin, NSAIDs (e.g. ibuprofen, diclofenac), and other antiplatelet medicines significantly increase the risk of bleeding
- Many antibiotics (e.g. metronidazole, fluoroquinolones, some cephalosporins) and antifungals can increase warfarin’s effect and raise your INR
- Sudden large changes in intake of vitamin K-rich foods (leafy greens, broccoli) can reduce warfarin’s effect and lower your INR
- Alcohol, certain herbal supplements (e.g. ginkgo, St John’s Wort), and many other prescription medicines can interact – inform your doctor and pharmacist of everything you take
Quick Tips
- Attend all scheduled INR blood tests so your doctor can adjust your dose safely
- Keep your vitamin K intake (green leafy vegetables) fairly consistent week to week rather than avoiding it completely
- Never start, stop, or change the dose of any other medicine, supplement, or herbal product without telling your doctor or pharmacist
- Watch for and report unusual bruising, bleeding, or dark stools promptly
- Carry an anticoagulant alert card or inform any healthcare provider, including your dentist, that you are taking warfarin before any procedure
- Limit alcohol intake, as it can affect how your body processes warfarin
Frequently Asked Questions
Is Orfarin 5mg Tablet a prescription medicine?
Yes. Orfarin 5mg Tablet is a prescription-only medicine (POM). It can only be supplied against a valid prescription written by a registered doctor, and it should be used only by the person named on the prescription label.
What does Orfarin 5mg Tablet contain?
Orfarin 5mg Tablet is supplied as a tablet and contains Warfarin sodium 5mg. The full composition is listed in the Composition section on this page and on the product packaging.
Why is there no information here about what Orfarin 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.
How should I take Orfarin 5mg Tablet?
Take it exactly as written on your prescription label. Do not increase, reduce or skip doses on your own, and do not continue beyond the period your doctor has prescribed. Practical handling steps are set out in the Directions for Use section on this page.
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.
How should I store Orfarin 5mg Tablet?
Store below 30°C in a dry place, away from direct sunlight and out of reach of children. Keep it in the original pack until use, and do not use it after the expiry date printed on the packaging.
What should I do if I notice side effects?
Tell your doctor or pharmacist about any reaction that concerns you, and seek medical care immediately for signs of a severe reaction such as difficulty breathing, swelling of the face, lips or throat, or a widespread rash. Reported reactions are listed in the Side Effects section on this page.
Can I stop taking Orfarin 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 Orfarin 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 Orfarin 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 Orfarin 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.
