Niacinamide Oral

Niacinamide Oral Uses

Niacinamide (nicotinamide) is a form of vitamin B3 (niacin) and is used to prevent and treat niacin deficiency (pellagra). Niacin deficiency can cause diarrhea, confusion (dementia), tongue redness/swelling, and peeling red skin. Niacinamide is often used instead of niacin because it causes fewer side effects (e.g., flushing). Unlike niacin, niacinamide does not help correct blood fat levels and cannot be substituted for niacin if you are being treated for a blood fat problem (e.g., high cholesterol).

Niacin deficiency may happen as a result of poor diet, certain medical conditions (e.g., alcohol abuse, malabsorption syndrome, Hartnup disease), or long-term use of certain medications (e.g., isoniazid). It is best to get your vitamins from healthy foods. A multivitamin may be recommended by your doctor instead of niacinamide because poor diet usually causes deficiencies in more than one vitamin. Vitamins help to support the body's ability to make and break down natural substances (metabolism) and are needed for good health.

How To Use Niacinamide Oral

Take this product by mouth as directed, usually once or twice daily. Follow all directions on the product package, or use as directed by your doctor. If you are uncertain about any of the information, consult your doctor or pharmacist.

If you take certain drugs to lower blood fats (bile acid-binding resins such as cholestyramine or colestipol), take niacinamide at least 4 to 6 hours before or after taking these medications. These products may bind with niacinamide, preventing its full absorption.

If your condition persists or worsens, or if you think you may have a serious medical problem, seek immediate medical attention.
