    Before taking Lamprene

    In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

    Allergies

    Tell your doctor if you have ever had any unusual or allergic Reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

    Pediatric

    Appropriate studies have not been performed on the relationship of age to the effects of clofazimine in the pediatric population. Safety and efficacy have not been established.

    Geriatric

    Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of clofazimine in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

    Clofazimine may cause orange-pink to brownish-black discoloration of the skin within a few weeks after you start using it. Because of the skin discoloration, some patients may become depressed. It may also cause your sweat, tears, spit, urine, stools, and the whites of your eyes to turn red or brownish-black in color. The discoloration will go away when you stop using this medicine. However, it may take several months or years for the skin to clear up completely. If skin discoloration causes you to feel very depressed or to have thoughts of suicide, check with your doctor right away.

    Clofazimine may cause dry, rough, itchy, or scaly skin. You may use a skin cream, lotion, or oil may help treat this problem.

    Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
