How to Minimize Side Effects of Niacin

Niacin, also known as nicotinic acid or vitamin B3, is a naturally occurring B vitamin used in therapeutic amounts to lower total cholesterol and lower the risk of heart attack by boosting levels of high-density lipoprotein, or "good," cholesterol. Therapeutic amounts of niacin are available. Niacin use is associated with a number of common side effects, including upset stomach, temporary skin redness and the feeling of skin warmth known as flushing and dizziness. These side effects can be minimized by following certain steps.

Tips and Warnings

• Consult your doctor to determine what dose of niacin is best for you. If you experience many side effects, your doctor may advise you to lower your dose. If you continue to experience unwanted flushing, consult your doctor about the possibility of taking a form of niacin that does not produce the flushing effect.
• Consult your doctor before starting this or any medicine. Report any side effects to your doctor. Consult your doctor before taking aspirin with the niacin. Note that severe, and less common side effects can include allergic reaction, bloody stools, flu-like symptoms, muscle pain, cloudy vision, or chest tightness. Do not take niacin if you have a history of stomach ulcers or liver disease. Possible drug interactions with niacin include antibiotics, anticoagulants, blood pressure medications, cholesterol-lowering medications, diabetes medications, Isoniazid and nicotine patches.
