Use niacin exactly as directed on the label, or as prescribed by your doctor. Read all medication guides or instruction sheets.
Niacin can cause flushing (warmth, itching, redness, or tingly feeling under your skin). These effects should disappear over time as you keep taking the medicine. Flushing may be worse if you drink alcohol or hot beverages shortly after taking niacin.
Swallow the capsule or tablet whole and do not crush, chew, break, or open it.
Your dose needs may change if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using only the form and strength your doctor prescribes.
If you stop taking niacin for any length of time, talk with your doctor before starting the medication again. You may need to restart the medication at a lower dose.
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using this medicine.
Niacin is only part of a complete treatment program that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
Your doctor may recommend you take aspirin or an NSAID (such as ibuprofen, Advil, or Aleve) to help prevent flushing. Keep using these medicines for as long as your doctor has prescribed.
Store at room temperature away from moisture and heat.
