This is a good question to ask a midwife you want to hire because the answer is, it depends.
The definition of a hemorrhage during a normal vaginal birth, is blood loss of more than 2 cups in the first few hours after birth, or more than 4 cups within the first 24 hours afterwards.
There are the 3 types of medications typically used for postpartum hemorrhage in out-of-hospital settings. These are:
Synthetic oxytocin AKA pitocin.
Pitocin can be administrated in IV form or intramuscularly, as a shot in the thigh. In out-of-hospital settings pitocin is more often given via a shot. Pitocin works quickly to control bleeding but does not last longer than 10 minutes, so it may have to be repeated, if the bleeding is not controlled by then. It doesn’t have significant negative side effects, although there have been some studies that show it slightly delays milk production, and is correlated with slightly increased rates of postpartum mood disorders.
Misoprostol AKA cytotec
Cytotec works really well to cause contractions of the uterus to slow a hemorrhage. It also has the negative side effect of causing a potential fever and loose stools. It comes in pill form and is either given to the mom orally to chew up and put in her cheek or under her tongue, or it is administered rectally.
Methylergonovine Maleate AKA Methergine
Methergine cannot be given to women who have high blood pressure. It is administered orally in pill form, or intramuscularly via a shot in the leg. It works well to contract the lower segment of the uterus. Methergine has several negative side effects, including loose stools, lowered breastmilk production, changes in blood pressure, and nausea.
