Warfarin Tablets belong to a group of drugs called anti-coagulants. You take Warfarin Tablets to help thin your blood if you have had a heart problem, problems with blood clots or your blood flow. You may also be given Warfarin Tablets if you have been fitted with a replacement heart valve.
Do not take Warfarin Tablets within 24 hours of surgery or giving birth to a child.
Tell your doctor if you are taking, have recently taken or might take any other medicines. Many drugs may increase or decrease the effects of Warfarin Tablets. It is particularly important to tell your doctor if you are taking, or have recently taken any of the medicines listed below:
Do not take any other drug without speaking to your doctor first.
Do not drink large amounts of alcohol while taking Warfarin Tablets.
Drinking cranberry juice or taking other cranberry products (for example capsules or concentrates), might increase the effect of Warfarin Tablets in “thinning” the blood. You should therefore avoid drinking/taking these products whilst taking Warfarin Tablets. If you have been advised to take cranberry juice or other products for medical reasons (e.g. bladder infections), or are regularly drinking or taking cranberry products, you should contact your anticoagulant clinic or health advisor before making any changes to the amount you drink/take. Your doctor or clinic may wish to monitor you more frequently while you are taking any cranberry product.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
