Approved for medical use in 1977, Dinoprostone is used in “labor induction, bleeding after delivery, termination of pregnancy, and in newborn babies to keep the ductus arteriosus open”. According to mayoclinic.org, Dinoprostone works by causing the cervix to open and the uterus to contract the way it does during labor. Bear in mind that this medicine is typically given into the vagina or cervix. Before using it, you should first tell your doctor about your allergies, or if you have any other medical issues, especially if you’re being treated for heart/liver/ kidney disease, or if you’ve ever had unexplained vaginal bleeding during pregnancy. You should also tell them if you’re using other drugs, or if you’re breastfeeding. When it comes to the side effects of Dinoprostone, they include diarrhea, headache, flu symptoms, and very bad dizziness – All of which require immediate medical help. So, don’t forget to call your doctor when you experience any of these side effects.
