What is Niavasc?

Niavasc 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).

Niaspan is used to lower the risk of a heart attack in people who have high cholesterol and who have a history of heart attacks. Niaspan can also be used with another cholesterol medicine to slow down the build-up of fatty deposits in your arteries.

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

How should I take Niavasc ?

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

Niavasc 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 this medicine.

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 Niavasc 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 Niavasc.

Niavasc 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.
