Avoid drinking hot beverages shortly after taking Niaspan ER. Hot drinks can worsen the flushing effect (warmth, itching, redness, or tingly feeling under your skin).
Avoid drinking alcohol while taking Niaspan ER. Alcohol may increase your risk of liver damage, and can also worsen the flushing effects of this medicine.
Avoid taking colestipol (Colestid) or cholestyramine (Locholest, Prevalite, Questran) at the same time you take Niaspan ER. If you take either of these other medications, take them at least 4 to 6 hours before or after you take Niaspan ER.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
