Brain cell function requires a constant delivery of oxygen and glucose from the bloodstream. A stroke, or cerebrovascular accident (CVA), occurs when blood supply to part of the brain is disrupted, causing brain cells to die. Blood flow can be compromised by a variety of mechanisms.

Niaspan (niacin) is a B-complex vitamin. Niaspan is available in generic form as niacin. Niaspan is used along with dietary changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in the blood. It is also used to prevent and treat pellagra, also known as niacin deficiency, a disease caused by inadequate diet and other medical problems. Common side effects may include: headache, blurred vision, nausea, vomiting, or diarrhea.
Niaspan is available as a tablet or an extended-release tablet to be taken orally. It should be taken at bedtime, after a low-fat snack. Doses should be individualized according to patient response. Therapy with Niaspan must be initiated at 500 mg at night to reduce the incidence and severity of side effects that may occur during early treatment. Caution should be used when Niaspan is used in patients with unstable angina or in the acute phase of a myocardial infarction (MI), especially when such patients are also receiving vasoactive drugs, such as nitrates, calcium channel blockers, or adrenergic blocking agents. If patients become pregnant, they should stop taking Niaspan and consult with their doctor. Women who are breastfeeding should not use Niaspan.
Our Niaspan Drug Center provides a comprehensive view of available drug information as well as related drugs, user reviews, supplements, and diseases and conditions.
