Side effects
Pethidine has a sedative effect and makes women drowsy and their breathing shallow. Many women feel very sick, so it is given with another drug to prevent sickness. Some women become very weepy after they have had pethidine.
Pethidine given during labour crosses the placenta with the result that some babies are slow to start breathing after they are born. Every delivery room carries a supply of a drug(narcan) that can reverse the effects of pethidine and this can be quickly injected into the baby if he is drowsy. However, the pethidine will linger in the baby’s system for up to a week and may make the baby unresponsive and difficult to feed in the early days of his life.
