Do not use alprostadil if you have a penile implant unless advised by doctor.
If using the alprostadil suppository, use a condom when having sexual intercourse with a pregnant female. Although harm to the fetus is unlikely, using a condom will protect the fetus from exposure to this medicine. If a woman can become pregnant, use of contraceptive methods is recommended because the effects of this medicine on early pregnancy are not known.
Use alprostadil exactly as directed by your doctor . Do not use more of it and do not use it more often than your doctor ordered. If too much is used, the erection lasts too long and does not reverse when it should. This condition is called priapism. If the erection is not reversed, the blood supply to the penis may be cut off and permanent damage may occur.
Contact your doctor immediately if the erection lasts longer than 4 hours or if it becomes painful. This may be a sign of priapism and must be treated right away to prevent permanent damage.
If you notice bleeding at the place where you injected the medicine, put pressure on the spot until the bleeding stops. If it doesn't stop within 10 minutes, check with your doctor.
