What is a side effect of Niacin?

Niacin, also known as vitamin B3, is commonly used to manage cholesterol levels and improve cardiovascular health. One of the most notable side effects associated with niacin is flushing. This flushing occurs due to the release of prostaglandins, which are chemicals in the body that cause blood vessels to dilate, leading to increased blood flow to the skin. As a result, individuals may experience a warm sensation, redness, or a burning feeling on the face and upper body.

Flushing is particularly common when an individual starts taking niacin or increases their dose. While it can be uncomfortable, it is usually not serious and often diminishes over time with continued use. Understanding this side effect is important for anyone taking niacin, as it helps set expectations and encourages adherence to the medication.

Other choices, while potential side effects of various medications or conditions, are not typically associated with niacin in the same prominent way that flushing is.
