Niacinamide and Flushing
Niacinamide supplements can cause flushing of your face and trunk when you begin treatment or increase dose, according to MayoClinic.com. Flushing is a warm, tingling or itchy feeling which often accompanied by reddening of the skin, rapid heartbeat, shortness of breath, dizziness and sweating. Niacinamide causes flushing by dilating blood vessels on the surface of the skin.
Niacinamide Flush Treatment
Niacinamide flushing is usually harmless, but causes great discomfort which can lead to discontinuation of the drug. You can reduce flushing by taking aspirin or non-steroidal anti-inflammatory drugs 30 minutes before the niacinamide. Using an antihistamine 15 minutes before taking niacinamide also helps reduce flushing, according to MayoClinic.com. Consult your doctor about using using slow-release niacinamide supplements. Time-released niacinamide supplements cause less flushing than regular supplements.
Niacinamide supplements are available alone or in combination with other vitamins. Take niacinamide tablets with food to reduce stomach irritation. Do not take large doses of vitamins while you are taking niacinamide unless your doctor tells you so. If you have high blood pressure or diabetes, consult your doctor before you take niacinamide. Niacinamide can worsen these conditions. Common side effects of niacinamide include headache, dizziness, diarrhea, nausea and stomach upset, according to Drugs.com.
