Final answer:
Flushing can be caused by nicotinic acids, a type of lipid medication used to lower cholesterol levels. Taking a low dose of aspirin or an NSAID can help reduce this side effect.
Step-by-step explanation:
Flushing is a common side effect of nicotinic acids, also known as niacin. Niacin is a type of lipid medication used to help lower cholesterol levels in the blood. Flushing occurs when blood vessels in the skin widen, causing redness, warmth, and sometimes itching. This side effect can be reduced by taking a low dose of aspirin or a nonsteroidal anti-inflammatory drug (NSAID) about 30 minutes before taking niacin.
