Niacin 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.
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, Nicotinex 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.
