What is niacin?

Niacin is used to lower blood levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides, and increase levels of "good" cholesterol (high-density lipoprotein, or HDL).

Niacin may also be used for purposes not listed in this medication guide.

You should not take niacin if you are allergic to it, or if you have:

Tell your doctor if you have ever had:

  • liver disease;
  • heart disease, chest pain (angina);
  • gout; or
  • diabetes.

It is not known whether niacin will harm an unborn baby. You may not be able to use this medicine during pregnancy. Tell your doctor right away if you become pregnant.

You should not breastfeed while using niacin.

Niacin is not approved for use by anyone younger than 18 years old.

How should I take niacin ?

How should I take niacin ?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Niacin can cause flushing (warmth, itching, redness, or tingly feeling under your skin). These effects should disappear over time as you keep taking the medicine. Flushing may be worse if you drink alcohol or hot beverages shortly after taking niacin.

Swallow the capsule or tablet whole and do not crush, chew, break, or open it.

Your dose needs may change if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using only the form and strength your doctor prescribes.

If you stop taking niacin for any length of time, talk with your doctor before starting the medication again. You may need to restart the medication at a lower dose.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using niacin.

Niacin is only part of a complete treatment program that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.

Your doctor may recommend you take aspirin or an NSAID (such as ibuprofen, Advil, or Aleve) to help prevent flushing. Keep using these medicines for as long as your doctor has prescribed.

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
