USES: Tretinoin is used with other medications (e.g., chemotherapy) to treat a certain type of cancer of the white blood cells (APL-acute promyelocytic leukemia). APL is a disease of too many white blood cells that do not mature or function properly. This medication is used to lessen the signs and severity of this disease (induce remission). Further treatment after remission will be determined by your doctor. Tretinoin works by promoting the growth of normal, mature cells in the bone marrow and blood. This medication helps to reverse symptoms of APL such as infections, tiredness, and bleeding. Tretinoin belongs to a class of drugs known as retinoids, which is related to vitamin A.
