Is Oxytocin safe?
Obstetric risks well documented
As a childbirth drug, oxytocin has well-documented risks. Excessive uterine contractions can stress the fetus. The uterus can rupture in women with prior surgery. Long infusions can cause water retention and low sodium. Postpartum hemorrhage can occur when the uterus stops responding. The boxed warning against elective induction reflects the FDA's judgment. Inducing labor without a medical reason does not offer benefits that outweigh these risks. 213
In trials, intranasal oxytocin has been well tolerated over short courses. Nasal irritation and headache were the main complaints. No one knows the effect of repeated use over months. No one knows the effect in people with conditions the trials excluded. Sprays sold online are unregulated. So the dose and purity of what is in the bottle are also unknown. 8914
