How to Use niacin

Oral tablet

Take this medicine by mouth with a glass of water. Follow the directions on the prescription label. Take with a low-fat meal or snack. Take your medicine at regular intervals. Do not take your medicine more often than directed. Do not stop taking except on the advice of your doctor or health care professional.

Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed.

What should I tell my health care provider before I take this medicine?

They need to know if you have any of these conditions:

  • bleeding problems
  • if you frequently drink alcohol containing drinks
  • liver disease
  • ulcers of intestine or stomach
  • an unusual or allergic reaction to niacin, other medicines, foods, dyes, or preservatives
  • pregnant or trying or get pregnant
  • breast-feeding
What if I miss a dose?

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

What should I watch for while using this medicine?

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?

Keep out of the reach of children.

Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F). Keep container tightly closed. Throw away any unused medicine after the expiration date.
