WHAT GEMHEXAL IS USED FOR
This medicine is used to lower high cholesterol, triglycerides and other fats in the blood.
Gemhexal does not reduce the cholesterol that comes from fat in food. Therefore, other measures such as a low fat diet, exercise
and weight control need to be followed.
It contains the active ingredient gemfibrozil.
Gemfibrozil belongs to a group of medicines called fibric acid derivatives (fibrates).
It is not exactly known how gemfibrozil works. It is thought to work by lowering "bad" (LDL) cholesterol and triglyceride
levels while raising "good" (HDL) cholesterol. Lowering "bad" cholesterol and triglyceride levels helps to keep your blood
vessels unblocked. This reduces the risk of heart and blood vessel disease, heart attacks, angina and strokes.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.
There is not enough information to recommend the use of this medicine for children.
