How do Zydus Warfarin Sodium Tablets, USP work?
Warfarin is an anticoagulant drug which is sometimes referred to as a “blood thinner”. Warfarin, however, works a little differently in that it actually slows down or prolongs the time it takes for your blood to clot. This helps prevent blood clots from forming or growing larger.

Why am I taking Zydus Warfarin Sodium Tablets, USP?
Your physician has prescribed Warfarin to help manage a condition in which dangerous blood clots could potentially form. Some of the conditions are as follows:

  • Thrombonphlebitis in the legs
  • Hereditary disorder
  • Heart valve disease or an artificial hear valve
  • Heart attack

How often should I take Zydus Warfarin Sodium Tablets, USP?
Adhere to your physician’s directions exactly as it is extremely important to strictly follow your prescribed dosage schedule. You will be carefully monitored utilizing blood tests to ensure correct levels of warfarin are in your bloodstream. Your physician will also advise you to take warfarin once a day and at the same time each day. The best idea is to tie in taking your warfarin with another daily activity such as a meal time or even brushing your teeth in the morning. You may want to keep a calendar as well.

How much Zydus Warfarin Sodium Tablets, USP should I take?
Your dose is dependent upon the effect warfarin is having on your blood and may be changed by your physician based upon your blood tests. Blood tests that help determine how fast your blood clots are called a PT (prothrombin time) or protime. Your physician may record your PT as an INR (international normalized ratio). Utilizing your PT/INR test results, your physician will adjust your dose until the PT/INR is at a level to help your blood from forming harmful clots.

It is extremely important to determine the correct dose so in the beginning your blood will be tested frequently, maybe even daily. Once your PT/INR results are correct and stable, your physician may perform the blood tests less frequently. It is very important to keep your physician informed of any changes to your health, diet, other medications, or even your exercise routine in that these could all have an effect on warfarin in your bloodstream.
