Niaspan Controlled-Release works by reducing LDL (“bad”) cholesterol and triglycerides and increasing HDL (“good”) cholesterol. Niaspan contains niacin, also called nicotinic acid, a B vitamin (vitamin B3). It occurs naturally in plants and animals and is present in many multiple vitamin supplements.

Niaspan lowers cholesterol levels, reducing the risk for a second heart attack, slows or treats hardening of the arteries, and lowers very high serum triglyceride levels. It is used in combination with diet.

Niaspan may also be used for purposes other than those listed in this medication guide.
