How opioids work for labor pain
Opioids suppress how you perceive pain, and they calm your emotional response to pain. They do this by reducing the number of pain signals sent by the nervous system to the brain. They also reduce the brain's reaction to those pain signals.
An opioid can help you relax between contractions and decrease the
pain. But it does not take all the pain away.
Opioids make you drowsy for a
short time. They can also slow your labor. But they are less likely than
epidural anesthesia to cause you to have a forceps or
vacuum delivery.footnote 1
The most common side effects of opioids include:
Feeling dizzy or lightheaded, or like you might faint.
Feeling sick to your stomach or vomiting.
Opioids are not used when you are close to delivery. That's because they can
affect a newborn's breathing. They can also make
the baby sleepy and less interested in breastfeeding if they are given close to delivery.
