Hello.. thanks for writing us. cytopan contains Misoprostol that promotes uterine contraction and cervix ripening and evacuation of uterine contents.. It is given either intravaginally or orally( not to swallow, keep below tongue or in between gum and cheek) every 12 or 24 hourly.. Can cause severe abdominal pain, heavy bleeding or chills and fever usually self limiting but if heavy seek urgent medical attention. Usually one dose is sufficient but if evacuation is not complete should be repeated under medical guidance only. Good luck
