Special warnings about Niaspan

Niaspan is an extended-released form of niacin. It is not interchangeable with immediate-release or sustained-release forms of niacin.

Niaspan can cause problems if your liver is weak. Before you start taking this medication, your doctor may order a blood test to check your liver. Blood tests will probably be repeated 6 and 12 weeks after you start taking Niaspan and periodically after that. While you are taking Niaspan, your doctor will monitor you very closely if you have ever had liver disease or if you are or have ever been a heavy drinker.

Do not drink alcohol or hot beverages with Niaspan because they may intensify the flushing and itching effect of the medication.

Niaspan should be used with caution if you have diabetes, a heart condition, or problems with gout. If you have diabetes, tell your doctor if you have a change in blood sugar levels while taking Niaspan. Also use Niaspan with caution if you have kidney problems.

Before undergoing surgery, make sure the doctor is aware that you are taking Niaspan. This medication tends to slow the clotting process, and could prolong bleeding.
