Minprostin – Dinoprostone uses, dose and side effects


1 mg and 2 mg vaginal gel

What Minprostin is and what it is used for

Minprostin contains the active substance dinoprostone. Dinoprostone belongs to a group of medicines called prostaglandins. Dinoprostone softens the cervix and opens it so that childbirth can take place. It also triggers contractions which help the baby to come out of the womb.

Minprostin is used to initiate labor during or near the end of pregnancy. There can be several reasons why you want to start labor. Ask your doctor if you want to know more.

Dinoprost contained in Minprostin may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
