gemfibrozil

COMMON BRAND NAME(S): Lopid

GENERIC NAME(S): GEMFIBROZIL

Uses

Gemfibrozil is used along with a proper diet to help lower fats (triglycerides) and raise "good" cholesterol (HDL) in the blood. It may also help to lower "bad" cholesterol (LDL). Gemfibrozil belongs to a group of drugs known as "fibrates." It works by decreasing the amount of fat produced by the liver. Lowering triglycerides in people with very high triglyceride blood levels may also decrease the risk of pancreas disease (pancreatitis). However, gemfibrozil might not lower your risk of a heart attack or stroke. Talk to your doctor about the risk and benefits of gemfibrozil.

In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, drinking less alcohol, losing weight if overweight, and stopping smoking.

How to use gemfibrozil

Take this medication by mouth as directed by your doctor, usually twice a day (30 minutes before your morning and evening meals).

Dosage is based on your medical condition and response to treatment.

If you also take certain other drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take gemfibrozil at least 1 hour before or at least 4-6 hours after taking these medications. These products can react with gemfibrozil, preventing its full absorption.

Take this medication regularly in order to get the most benefit from it. Remember to take it at the same times each day. It is important to continue taking this medication even if you feel well. Most people with high cholesterol/triglycerides do not feel sick.

It is very important to continue to follow your doctor's advice about diet and exercise. It may take up to 3 months before you get the full benefit of this drug.

Side Effects

Stomach upset, stomach/abdominal pain, or unusual taste may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may infrequently cause gallstones and liver problems. If you notice any of the following unlikely but serious side effects, tell your doctor immediately: severe stomach/abdominal pain, persistent nausea/vomiting, yellowing eyes/skin, dark urine.

This drug may infrequently cause muscle problems (which can rarely lead to a very serious condition called rhabdomyolysis). Tell your doctor immediately if you develop any of these symptoms: muscle pain/tenderness/weakness (especially with fever or unusual tiredness), change in the amount of urine.

Tell your doctor immediately if any of these rare but serious side effects occur: signs of infection (such as fever, persistent sore throat), easy bruising/bleeding, unusual tiredness, irregular heartbeat, numbness/tingling of arms/legs.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
