Atromid-S Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Atromid-S (clofibrate capsules) is an antilipidemic drug used to lower high levels of cholesterol (a type of fat) in the blood. It is especially good at lowering triglycerides and very-low-density lipoprotein (VLDL) (a form of cholesterol). The brand name of this medication is discontinued, but generic versions may be available. Common side effects include bloating, flatulence, nausea, vomiting, diarrhea, headache, dizziness, drowsiness, or impotence.

The recommended dosage of Atromid-S for adults is 2 g daily in divided doses. Atromid-S may interact with anticoagulants, insulin or oral diabetes medications, or other cholesterol-lowering drugs. Tell your doctor all medications and supplements you use. Atromid-S may pass into the system of a fetus and can build up dangerously in unborn babies, who do not yet have the ability to break down and pass this drug from the body. Tell your doctor if you are pregnant before taking Atromid-S. This drug passes into breast milk. Since babies do not yet have the ability to break down this drug, a dangerous buildup could occur. Consult your doctor before breastfeeding.

Our Atromid-S (clofibrate capsules) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
