I've been given pitocin three times (that I know of) . Once was actually for labor.. Most every birth in the hospital the mom gets it. I would say that 95% of the time it's for doctor's convenience. They don't want to wait around until your body is ready to expel the placenta. So to convenience them we deal with swollen legs and sometimes heart rate problems as the drug leaves our body. I battled the hospital for a month getting pitocin off my charges because a midwife went against my birth plan. To say I don't like pitocin is a severe understatement.
