What should I watch for while using Niacin (Vitamin B3)?

Visit your doctor or health care professional for regular checks on your progress. You may need regular tests to make sure your liver is working properly.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.

Do not drink hot drinks or alcohol at the same time you take this medicine. Hot drinks and alcohol can increase the flushing caused by this medicine, which can be uncomfortable. Alcohol also can increase possible dizziness. Taking aspirin or an NSAID like ibuprofen 30 minutes before this medicine may help reduce flushing.

This drug is only part of a total heart-health program. Your doctor or a dietician can suggest a low-cholesterol and low-fat diet to help. Avoid alcohol and smoking, and keep a proper exercise schedule.

If you are diabetic, close regulation and monitoring of your blood sugars can help your blood fat levels. This medicine may change the way your diabetic medication works, and sometimes will require that your dosages be adjusted. Check with your doctor or health care professional.

Where should I keep my medicine?
