What Prostin E2 is used for

Prostin E2 can be used to bring on (induce) labour in women who have a normal pregnancy. It works by softening and dilating the neck of the womb and stimulating contractions.

Your doctor may have prescribed Prostin E2 for another reason. Ask your doctor if you have any questions about why Prostin E2 has been prescribed for you.

This medicine is available only with a doctor’s prescription. It is not addictive.
