Glasdegib must not be taken by patients who are pregnant or who may become pregnant. There is a high risk that glasdegib will cause severe birth defects (physical problems that are present at birth) or death of the unborn baby.
If you are a female who can become pregnant, you must have a negative pregnancy test within 7 days before you start treatment with glasdegib.

Talk to your doctor about birth control options that will work for you.
If you are a male with a female partner who can become pregnant or who is pregnant, you should know glasdegib may be present in the semen and may cause harm to the unborn baby. Use a condom during your treatment with glasdegib and for at least 30 days after the final dose even if you have had a vasectomy (surgery to prevent sperm from leaving your body and causing pregnancy). Do not donate semen during your treatment and for at least 30 days after yourfinal dose.
If you have had unprotected sex, think that your birth control has failed, or think you or your female partner may be pregnant call your doctor right away.
Do not donate blood or blood products during your treatment with glasdegib and for at least 30 days after your last dose.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with glasdegib and each time you refill your prescription.

WHY is this medicine prescribed?
Glasdegib is used along with cytarabine as a first treatment for acute myeloid leukemia (AML; a type of cancer that begins in the white blood cells) in people over 75 years of age, or in adults who have other medical conditions and can not be treated with other chemotherapy medications. Glasdegib is in a class of medications called hedgehog pathway inhibitors. It works by blocking the action of a protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells.
