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.

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.
