- Simcor®(as a combination product containing Niacin, Simvastatin)
WHY is this medicine prescribed?
Niacin is used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in your blood. Niacin is also used to prevent and treat pellagra (niacin deficiency), a disease caused by inadequate diet and other medical problems. Niacin is a B-complex vitamin.
HOW should this medicine be used?
Niacin comes as a tablet and an extended-release (long-acting) tablet to take by mouth. The regular tablet usually is taken two to three times a day with meals, and the extended-release tablet is taken once a day, at bedtime, with food. Follow the directions on your prescription label or package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take niacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole; do not split, chew, or crush them.
Your doctor will probably start you on a low dose of niacin and gradually increase your dose.
Continue to take niacin even if you feel well. Do not stop taking niacin without talking to your doctor.
Are there OTHER USES for this medicine?
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
What SPECIAL PRECAUTIONS should I follow?
Before taking niacin,
- tell your doctor and pharmacist if you are allergic to niacin, aspirin, tartrazine (a yellow dye in some processed foods and drugs), or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially anticoagulants ('blood thinners') such as warfarin (Coumadin), medications for high blood pressure or diabetes and other vitamins. If you take insulin or oral diabetes medication, your dose may need to be changed because niacin may increase the amount of sugar in your blood and urine.
- tell your doctor if you drink large amounts of alcohol and if you have or have ever had diabetes; gout; ulcers; allergies; jaundice (yellowing of the skin or eyes); or gallbladder, heart, or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking niacin, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking niacin.
- you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how this drug affects you.
- remember that alcohol can add to the drowsiness caused by this drug.
- you should know that niacin causes flushing (redness) of the face and neck. This side effect usually goes away after taking the medicine for a few weeks. Avoid drinking alcohol or hot drinks around the time you take niacin. Taking aspirin or another nonsteroidal anti-inflammatory drug such as ibuprofen (Advil, Motrin) or naproxen (Aleve, Naprosyn) 30 minutes before niacin may reduce the flushing. If you take extended-release niacin at bedtime, the flushing will probably happen while you are asleep. If you wake up and feel flushed, get up slowly, especially if you feel dizzy or faint.
What SPECIAL DIETARY instructions should I follow?
Eat a low-cholesterol, low-fat diet, which includes cottage cheese, fat-free milk, fish, vegetables, poultry, and egg whites. Use monounsaturated oils such as olive, peanut, and canola oils or polyunsaturated oils such as corn, safflower, soy, sunflower, cottonseed, and soybean oils. Avoid foods with excess fat in them such as meat (especially liver and fatty meat), egg yolks, whole milk, cream, butter, shortening, pastries, cakes, cookies, gravy, peanut butter, chocolate, olives, potato chips, coconut, cheese (other than cottage cheese), coconut oil, palm oil, and fried foods.
What should I do IF I FORGET to take a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What SIDE EFFECTS can this medicine cause?
Niacin may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- itching, stinging, tingling, or burning of the skin
- blurred vision
If you experience any of the following symptoms, call your doctor immediately:
- fast heartbeat
- yellowing of the skin or eyes
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online [at Web Site] or by phone [1-800-332-1088].
What should I know about STORAGE and DISPOSAL of this medication?
