Warfin in tablet form is a medicine used to prevent thrombosis (blood clots) or to treat thrombosis or its complications. Warfin reduces the tendency to form blood clots. Your doctor will inform you about the treatment or prevention of which diseases this medicine is used for. Most often, the medicine is used to: prevent and treat deep vein thrombosis of the lower limbs (blood clots in the veins of the lower limbs) and pulmonary embolism (blood clots in the blood vessels of the lungs) prevent the formation of blood clots in patients with atrial fibrillation (heart rhythm disorder) prevent the formation or recurrence of blood clots after a heart attack prevent the formation of blood clots after heart valve replacement.

2. Important information before taking Warfin

• if the patient has a predisposition to bleeding from the gastrointestinal or urinary tract, e.g. previous complications related to bleeding from the stomach or intestines, diverticulitis or tumors
• if the patient is allergic to warfarin sodium or any of the other ingredients of this medicine (listed in section 6)
• if the patient is taking St. John's Wort (Hypericum perforatum)
• if the patient has dementia, psychosis, alcoholism or other conditions in which anticoagulant treatment cannot be used safely.

Warnings and precautions

Before starting to take Warfin, discuss it with your doctor or pharmacist if you are pregnant or planning to become pregnant if you have hypothyroidism or hyperthyroidism if you have heart failure associated with acute exacerbation episodes (episodes of increased swelling of the legs and shortness of breath) if you have other liver diseases not mentioned above or hepatitis if you have kidney failure if you are scheduled to have a dental or other surgical procedure, consult your doctor if you are currently taking, have recently taken, or are planning to take other medicines during treatment with Warfin (see "Warfin and other medicines"). You should avoid drastic changes in dietary habits, as the vitamin K content in food may affect warfarin treatment. Factors that may affect therapy include: switching to a vegetarian diet, a very restrictive diet, depression, vomiting, diarrhea, fatty diarrhea, or absorption disorders for other reasons.

Warfin and other medicines

Tell your doctor or pharmacist about all medicines you are taking, or have recently taken, and about medicines you plan to take, even those that are available without a prescription. This also applies to herbal medicines or natural products. Many medicines affect the action of Warfin - both reducing and increasing its effect. Do not start taking new medicines or stop taking medicines without consulting your doctor first. All changes in the dosage of concomitantly administered medicines may change the balance of the action of oral anticoagulants, so it may be necessary to perform laboratory tests to determine the INR (International Normalized Ratio) more frequently. If you need to take painkillers, consult your doctor. Most over-the-counter painkillers should not be taken with Warfin. However, medicines containing only paracetamol can be used for temporary pain or fever relief. Glucosamine (used for osteoarthritis) may increase the effect of Warfin. Herbal medicines and natural products If you are already taking some of the herbal medicines listed below, you should consult your doctor before stopping them. Herbal medicines containing ginkgo biloba, garlic, angelica, papaya, and salvia may increase the effect of Warfin. On the other hand, St. John's Wort and ginseng reduce the effect. Therefore, taking these herbal medicines should not be started or stopped during Warfin treatment without consulting a doctor.

Warfin with food and drink

Taking vitamin K affects Warfin treatment. Therefore, consuming products containing vitamin K should be as uniform as possible during Warfin treatment. Avoid sudden changes in diet. The richest source of vitamin K is green vegetables, leaves, and herbs. Some of them are listed below. It is not necessary to avoid eating them, but you should avoid changes in the daily amount of these products consumed. Sources rich in vitamin K include: beet leaves, avocado, broccoli, Brussels sprouts, cabbage, canola oil, chayote leaves, parsley, coriander, cucumber skin (but not cucumber without skin), endive, kale, kiwi, lettuce, mint, brown mustard, olive oil, parsley, peas, pistachios, purple seaweed, spinach, spring onion, soybeans, soybean oil, tea leaves (but not tea), turnip or watercress. Cranberry juice and other cranberry products may increase the effect of warfarin, so you should avoid consuming these products during warfarin treatment. Smoking may affect the effectiveness of warfarin. More frequent INR monitoring may be necessary if you have been smoking for a long time and quit smoking during Warfin treatment.

Pregnancy and breastfeeding

Your doctor should decide whether Warfin can be taken during pregnancy. If you are planning to become pregnant or are pregnant while taking Warfin, you must contact your doctor, as taking Warfin during pregnancy may harm the fetus. Warfin should not be taken during the first trimester and in the last four weeks of pregnancy, and if possible, Warfin should be avoided throughout the entire pregnancy, except in exceptional circumstances under specialist supervision. Warfarin sodium does not pass into breast milk. Therefore, you can breastfeed while taking Warfin.

Driving and using machines

Warfarin has no effect on the ability to drive vehicles or operate machines.

Warfin contains lactose

This medicine contains 85 mg of lactose (in the form of lactose monohydrate). If you have been diagnosed with intolerance to some sugars, you should contact your doctor before taking the medicine.

Other excipients

This medicine contains less than 1 mmol (23 mg) of sodium per dose, which means the medicine is considered "sodium-free".

3. How to take Warfin

You will receive detailed instructions from your doctor, hospital, or clinic on how to take Warfin. This medicine should always be taken according to the doctor's or pharmacist's recommendations. If you have any doubts, ask your doctor or pharmacist. It is very important to regularly perform blood tests. The dose of the medicine is individually adjusted for you and may change from day to day. It is absolutely necessary to follow the dosage instructions and undergo laboratory tests.

Taking a higher dose of Warfin than recommended

If you or someone else has taken an overdose of Warfin, contact your doctor for further instructions. If a large dose of the medicine has been taken, activated charcoal can be given as first aid, but you should still contact your doctor as soon as possible. Inducing vomiting should not be used as a first aid measure.

Missing a dose of Warfin

If you forget to take a dose of the medicine within the first 12 hours, you can take the missed dose as soon as possible. Take the next dose at the usual time. If more than 12 hours have passed since you forgot to take the dose, divide the missed dose into two or three parts and take it with the next doses so that the weekly dose does not change. If you have missed more than one dose, contact your doctor for further dosing instructions. Never take a double dose or two doses, one after the other.

Stopping Warfin treatment

The anticoagulant effect of the medicine may persist for 2 to 5 days after stopping Warfin treatment. If you have any further doubts about taking the medicine, ask your doctor or pharmacist.
