Why is this medication prescribed?
Tretinoin is used to treat acute promyelocytic leukemia (APL; a type of cancer in which there are too many immature blood cells in the blood and bone marrow) in people who have not been helped by other types of chemotherapy or whose condition has improved but then worsened following treatment with other types of chemotherapy. Tretinoin is used to produce remission (a decrease or disappearance of signs and symptoms of cancer) of APL, but other medications must be used after treatment with tretinoin to prevent the cancer from returning. Tretinoin is in a class of medications called retinoids. It works by slowing or stopping the growth of cancer cells by causing immature blood cells to develop into normal blood cells.
How should this medicine be used?
Tretinoin comes as a capsule to take by mouth. It is usually taken twice a day for up to 90 days. Take tretinoin at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tretinoin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take tretinoin even if you feel well. Do not stop taking tretinoin without talking to your doctor.
