About innohep®

Find specific information about your innohep® treatment here

Your doctor will start by assessing the severity of your DVT along with other risk factors, such as whether you are currently undergoing cancer treatment. You may be prescribed tablets, injections or a combination of both and other treatments may also be available.

If you are unsure of why your doctor chose innohep® as a treatment, feel free to ask. The answer may help you understand your treatment process better.

innohep® is a low molecular weight heparin

The active ingredient in innohep® is called tinzaparin sodium (TIN-za PAR- in). The name does not exactly roll off the tongue, but when your doctor says low molecular weight heparin (LMWH), he or she is referring to a type of anticoagulant, which is a medicine that slows down the body’s natural clotting process.

Specifically LMWH anticoagulants inhibit the blood’s “coagulation cascade”, which is the series of steps and triggers that happen when the blood begins to clot. LMWH medicines interrupt this series by attaching to specific enzymes in the cascade and preventing them from working. As a result, the next factor in the coagulation cascade does not get triggered and the clotting process is slowed.

You may have a blood test before you start using this medicine and at intervals while you are using it; this is to check the level of the clotting cells (platelets) and potassium in your blood.

Elderly people

Because kidney problems are more likely if you are elderly, you may have a blood test to check how well your kidneys are working and to monitor the activity of innohep®.

Children and adolescents

innohep® is not intended for use in children and adolescents under the age of 18 years.

Other medicines and innohep®

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes any medicines bought without a prescription.

How much innohep® to use
