APO WARFARIN, 4MG, TABLET
This medication thins the blood and prevents blockage of blood vessels. It acts on certain blood elements involved in the coagulation process. Typically, it is used for the prevention of blood clots or for deep vein thrombosis (blood clots). It may also be used to assist in the treatment of heart attacks. It requires several days to take effect.
How to use this medication
Because this medication thins the blood, prolonged bleeding may occur if you injure yourself. Be careful when using sharp instruments or when you practice any activity or sport that may result in serious injury. The use of a soft-bristled toothbrush and an electric razor is recommended. Report any excessive or unusual bleeding to your doctor. Signs indicating that the dosage may be too high include:
- the presence of black or reddish stools;
- red or dark brown urine;
- bruising that occurs easily;
- gums bleeding while brushing your teeth;
- in women, abnormally abundant and prolonged menstrual bleeding.
The dosage of this medicine is adjusted according to the result of your blood test (INR). Regular blood tests are therefore essential. Advise the personnel taking the sample if you have forgotten to take one or more doses. While undergoing this treatment, do not consume alcohol, make any significant dietary changes, or take any medication containing acetylsalicylic acid (ASA, e.g., Aspirin) unless prescribed by your doctor.
This medication is typically used only once a day. However, your pharmacist may have suggested a different schedule that is more appropriate for you. It must be used regularly and continuously to maintain its beneficial effects. Be sure to keep an adequate supply on hand.
This medication may be taken with or without food.
Possible side effects
Aside from the risk of bleeding, this product has few side effects. If you think this medication may be causing side effects, talk to your health care professional. He or she can help you to determine whether or not the medication is the source of the problem.
As with most medications, this product should be stored at room temperature. Store it in a secure location where it will not be exposed to excessive heat, moisture or direct sunlight. Make sure that any leftover portion is disposed of safely.
Vitamin K can modify the effect of your oral anticoagulant. As it is obtained in the food you consume, you need to have a well-balanced diet and avoid radical changes of your diet. You do not have to eliminate every food that contains vitamin K, nor is there an ideal quantity of vitamin K to strive for. The secret is in a stable diet. Try to keep your vitamin K intake as stable as possible. If you are already fond of vitamin K-rich foods (e.g., broccoli, green cabbage, Brussels sprouts, spinach, liver, colza and soya oil, lentils, green tea, etc.), continue eating them in reasonable amounts, alternating with other dietary choices..
