To decrease the chance of developing side effects from Slo-Niacin, individuals should take the medication with food, and avoid consuming alcohol, hot beverages and spicy foods, notes WebMD. Taking a regular 325 milligram aspirin or a nonsteroidal anti-inflammatory drug, such as 200 milligrams of ibuprofen, 30 minutes before taking niacin may reduce flushing.

Serious side effects while taking Slo-Niacin include fainting, severe dizziness, abnormal heart rhythm, joint pain and swelling, states WebMD.

Individuals experiencing any serious side effects should contact a doctor immediately. Although rare, symptoms of an allergic reaction to Slo-Niacin, such as rash, itching, trouble breathing and swelling of the face or throat, require emergency medical attention.
