What is Niaspan?Niaspan is used along with diet and exercise to improve cholesterol levels when exercise and a low-fat diet alone have not been adequate. Niaspan increases "good" high-density lipoprotein (HDL) cholesterol in your body and also lowers the "bad" low-density lipoprotein (LDL) cholesterol and triglycerides.
What is the most important information I should know about Niaspan?Taking Niaspan is not a substitute for following a healthy low-fat and low-cholesterol diet and exercising to lower your cholesterol.
Your doctor will perform liver tests on you while you are taking Niaspan.
If you are currently on both a statin and Niaspan, be alert for any signs and symptoms of muscle pain, tenderness, or weakness, particularly during the initial months of therapy and when the dose of either drug is being increased. These may be the symptoms of a potentially serious condition.
If you stop taking Niaspan for an extended period, contact your doctor before you start taking it again. Your dose may need to be adjusted.
Flushing occurs with Niaspan and may last for several hours. Talk with your doctor if flushing becomes bothersome. Take Niaspan at bedtime so that flushing will occur during sleep.

Take aspirin or a nonsteroidal anti-inflammatory drug (NSAID), such as ibuprofen, 30 minutes before taking Niaspan to lessen flushing. Avoid ingesting alcohol, hot beverages, or spicy foods around the time of taking Niaspan to minimize flushing.
Niaspan may cause an increase in blood sugar levels. If you have diabetes, check your blood sugar levels more frequently during the first few months of therapy. Ask your doctor before you change your diet or the dose of your diabetes medicine.
