Niacor (niacin), also called nicotinic acid, is a B vitamin (vitamin B3) used to treat and prevent a lack of natural niacin in the body, and to lower cholesterol and triglycerides (types of fat) in the blood. Niacor is also used to lower the risk of heart attack in people with high cholesterol who have already had a heart attack. Niacin is sometimes used to treat coronary artery disease (also called atherosclerosis). Niacor is available in generic form. Common side effects of Niacor include flushing of the face and neck (warmth, redness, or tingly feeling), headache, itching, burning, sweating, or chills within 20 minutes of taking this medication. Flushing may persist for a few hours after use. These side effects should improve or go away as your body adjusts to Niacor. Other side effects of Niacor include dizziness, stomach upset, heartburn, nausea, vomiting, diarrhea, itching, dry skin, belching, gas, muscle pain, leg cramps, or sleep problems (insomnia).

The usual adult dosage of Niacor is 1 to 2 grams two or three times a day. Niacor may interact with other cholesterol-lowering drugs (atorvastatin, fluvastatin, lovastatin, pravastatin, simvastatin), blood thinners, multivitamins or mineral supplements containing niacin, blood pressure or heart medications. Tell your doctor all medications and supplements you use. Niacor should be used only when prescribed during pregnancy. This medication passes into breast milk. Consult your doctor before breastfeeding.
