Niacin For High Cholesterol (Systemic)

Other commonly used names are nicotinic acid; vitamin B 3 .
Niacin (NYE-a-sin) is used to help lower high cholesterol and fat levels in the blood. This may help prevent medical problems caused by cholesterol and fat clogging the blood vessels.
Some strengths of niacin are available only with your doctor's prescription. Others are available without a prescription, since niacin is also a vitamin. However, it is best to take it only under your doctor's direction so that you can be sure you are taking the correct dose.
Niacin for use in the treatment of high cholesterol is available in the following dosage forms:
Before Using This Medicine
If you are taking this medicine without a prescription, carefully read and follow any precautions on the label. For niacin, the following should be considered:
Allergies- Tell your doctor if you have ever had any unusual or allergic reaction to niacin. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Diet- Before prescribing medicine for your condition, your doctor will probably try to control your condition by prescribing a personal diet for you. Such a diet may be low in fats, sugars, and/or cholesterol. Many people are able to control their condition by carefully following their doctor's orders for proper diet and exercise. Medicine is prescribed only when additional help is needed and is effective only when a schedule of diet and exercise is properly followed.
Also, this medicine is less effective if you are greatly overweight. It may be very important for you to go on a reducing diet. However, check with your doctor before going on any diet.
Make certain your health care professional knows if you are on any special diet, such as a low-sodium or low-sugar diet.
Pregnancy- Studies have not been done in either humans or animals.
Before taking niacin, make sure your doctor knows if you are pregnant or if you may become pregnant. It may be necessary for you to stop taking this medicine or to take another medicine while you are pregnant. Be sure you have discussed the risks and benefits of the medicine with your doctor.
Breast-feeding- Niacin passes into human breast milk and may cause unwanted effects in nursing babies. It may be necessary for you to take another medicine or to stop breast-feeding during treatment. Be sure you have discussed the risks and benefits of the medicine with your doctor.
Children- There is no specific information comparing the use of niacin for high cholesterol in children with use in other age groups. However, use is not recommended in children under 2 years of age since cholesterol is needed for normal development.
Older adults- Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. Although there is no specific information comparing the use of niacin for high cholesterol in the elderly with use in other age groups, it is not expected to cause different side effects or problems in older people than in younger adults.
Other medicines- Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are using any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Other medical problems- The presence of other medical problems may affect the use of niacin. Make sure you tell your doctor if you have any other medical problems, especially:
