  • Avoid spicy foods and hot or alcoholic beverages around the time of taking NIASPAN FCT.
  • If the side effect flushing is bothersome, (see Side Effects and What to Do About Them, below), discuss it with your doctor, and your doctor may recommend that you take acetylsalicylic acid, if this is appropriate for you up to 30 minutes before taking NIASPAN FCT.
  • Be sure to tell your doctor about any vitamins or other nutritional supplements containing niacin (nicotinic acid, niacinamide, nicotinamide) you are currently taking.

Missed Dose

You should take NIASPAN FCT only once per day in the evening or at bedtime after a low-fat snack as prescribed. If you miss a dose, take your usual NIASPAN FCT dose the next evening; do not make up for missed doses by taking extra tablets.

If you stop taking NIASPAN FCT for a week or more, contact your doctor for instructions.

Side Effects and what to do about them

What is flushing?

  • Niacin sometimes causes redness, warmth, itching, and/or a tingling sensation on the face, neck, chest and back. This is a natural reaction signalling that niacin is in the bloodstream.
  • Most patients on NIASPAN FCT (extended-release niacin) will experience this sensation, usually at the start of therapy or when the dosing is increased. For most patients, the flushing occurs over the first 8 weeks of therapy and will become milder and less frequent as your body adjusts to NIASPAN FCT.
  • If flushing occurs, it usually does so within 2 to 4 hours after taking NIASPAN FCT and may last for a few hours.
  • In some patients, flushing may be more intense. Additional symptoms, such as rapid or pronounced heartbeat or dizziness, shortness of breath, sweating, chills, and/or swelling may occur; on rare occasions, fainting may occur.
  • If the flushing wakes you up and you wish to get out of bed, take your time and get up slowly – especially if you start to feel faint or dizzy, or if you take blood pressure medication.

Other important reactions to be aware of:

  • If you are diabetic, inform your doctor if you notice any changes in your blood sugar.
  • If you are taking another cholesterol lowering drug, you should inform your doctor if you experience any signs of muscle pain or weakness, as this may be a sign of a rare but serious adverse drug reaction.

Other than flushing, the side effects most often seen are stomach upset and diarrhea; rash and itching are occasionally observed.
