Use Niaspan ER exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Niaspan ER is sometimes taken at bedtime with a low-fat snack. Follow your doctor's instructions.
Niaspan ER can cause certain side effects, such as flushing (warmth, itching, redness, or tingly feeling under your skin). These effects can be made worse if you drink alcohol or hot beverages shortly after you take Niaspan ER. These effects should disappear over time as you keep taking the medication.
Take Niaspan ER with a full glass of cold or cool water. Taking the medication with a hot drink may increase your risk of side effects such as flushing. Do not crush, chew, break, or open an extended-release Niaspan ER tablet. Swallow it whole. Breaking or opening the tablet may cause too much of the drug to be released at one time. Extended-release tablets contain higher strengths of niacin than the regular tablets.
Niaspan ER can cause you to have unusual results with certain medical tests (urine tests). Tell any doctor who treats you that you are using this medicine.
If you stop taking Niaspan ER 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.
While using Niaspan ER, you may need blood tests at your doctor's office. Your kidney or liver function may also need to be checked. Visit your doctor regularly.
Niaspan ER is only part of a complete program of treatment that may also include diet, exercise, weight control, and other medications. Follow your diet, medication, and exercise routines very closely.
Store at room temperature away from moisture and heat.
