Well said Schmickers. Syntocinon helps to control bleeding by causing your uterus to contract. It has no effect on bleeding from tears. Syntocinon works within a few minutes of it being given (a few seconds if given into a vein). So why not wait and see if you need it first. Just remember, until the cord is clamped your baby is still receiving nutrients (and drugs if you have any) from you so I suggest that you do a little more research on this subject. Personally I think that giving syntocinon routinely is like taking a panadol tonight just in case you are going to get a headache in the morning
