Opioids are a type of pain relief that may be offered during labour in hospital. Common opioids include remifentanil, morphine, fentanyl, and pethidine. They can be given in different ways, such as through a pump that you control (often called a PCA), or as a dose given by your midwife or doctor. People respond differently to opioids, and the effects can vary depending on the medicine and how it is given.
