Na-500 Oral

Na-500 Oral Uses

Niacin (nicotinic acid) is used to prevent and treat niacin deficiency (pellagra). Niacin deficiency may result from certain medical conditions (e.g., alcohol abuse, malabsorption syndrome, Hartnup disease), poor diet, or long-term use of certain medications (e.g., isoniazid).

Niacin deficiency can cause diarrhea, confusion (dementia), tongue redness/swelling, and peeling red skin. Niacin is also known as vitamin B3 , one of the B-complex vitamins. Vitamins help to support the body's ability to make and break down natural compounds (metabolism) needed for good health. Niacinamide (nicotinamide) is a different form of vitamin B3 and does not work the same as niacin. Do not substitute unless directed by your doctor.

How To Use Na-500 Oral

See also Drug Interactions section.

Take this medication by mouth with food, usually once or twice a day or as directed by your doctor. Taking niacin on an empty stomach increases side effects (e.g., flushing, upset stomach). Follow all directions on the product package. If you are uncertain about any of the information, consult your doctor or pharmacist.

Niacin is available in different formulations (e.g., immediate, sustained release). If your doctor has prescribed niacin, do not switch strengths, brands, or forms because doing so may increase the risk of severe liver problems.

Sustained-release capsules and tablets must be swallowed whole. Check with your pharmacist whether you may break the tablet on the score line. Do not crush or chew extended-release tablets or capsules. Doing so can destroy the long action of the drug and may increase side effects.

To prevent flushing, do not take this medication with alcohol or hot drinks. Taking a plain (non-enteric-coated, 325-milligram) aspirin or a nonsteroidal anti-inflammatory drug (e.g., ibuprofen) 30 minutes before taking niacin may help prevent flushing. Consult your doctor or pharmacist for specific directions on aspirin/NSAID use before starting your niacin treatment to make sure it is right for you, especially if you are also using "blood thinners" (anticoagulants such as warfarin or heparins).
