Flushing is one of the most common side effects associated with niacin therapy. When you take niacin, especially in high doses or certain formulations like prescription niacin (Niacor) or extended-release niacin (Niaspan), your blood vessels dilate, causing a warm sensation and intense redness on your face, neck, and chest.

This reaction usually lasts for about 15 to 30 minutes, but it can be quite uncomfortable and alarming for some individuals. Additionally, some people may experience other skin reactions such as itching or tingling sensations during the flushing episode. Although these symptoms are generally harmless, if you experience any severe or persistent discomfort, it’s important to consult your healthcare provider.

It’s also worth noting that consuming yeast, milk, meat, or tortillas before taking niacin can potentially worsen the flushing effect.

Digestive Issues

Experiencing digestive issues can be a common occurrence when taking niacin, as the body may struggle to properly process and absorb this essential nutrient. Niacin side effects often include symptoms such as nausea, vomiting, diarrhea, and stomach pain. These digestive issues occur due to the vasodilating properties of niacin, which can lead to an increase in gastric acid secretion and gastrointestinal irritation.

Although these side effects are generally temporary and mild, it’s important to consult with a healthcare professional if they persist or worsen. In some cases, adjusting the dosage or switching to an extended-release form of niacin may help alleviate the digestive problems. It’s also recommended to take niacin with food or after meals to minimize gastrointestinal discomfort.

While digestive issues are a potential risk when taking niacin, it’s crucial not to discontinue its use without medical advice. Niacin plays a vital role in maintaining overall health and preventing certain conditions like pellagra. Therefore, understanding and managing these potential complications can help individuals continue reaping the benefits of this essential nutrient while minimizing any associated risks.

Headaches and Dizziness

Headaches and dizziness can sometimes occur when taking niacin, causing discomfort and imbalance. These side effects are commonly reported by individuals who are prescribed niacin for various medical conditions.
