Important Information:
MUSE (alprostadil) is a medicated pellet that is placed in the urinary opening using a disposable plastic applicator. MUSE should not be used by men who have sickle cell anemia or trait, leukemia or tumor of the bone marrow, allergy to alprostadil (the active ingredient in MUSE), or abnormal penile anatomy. Call your doctor immediately if your erection lasts 4 hours or more.

Men with certain heart problems should not use MUSE. Check with your doctor to see if your heart is healthy enough for sex before using MUSE. You should avoid activities such as driving or other hazardous tasks within one hour of using MUSE because you may become light-headed, dizzy or faint.

Remember that no medicine is for everyone. MUSE should not be used for intercourse with a pregnant woman without a condom. MUSE does not protect against sexually transmitted diseases. Side effects can include penile pain.
