Strong opioids (sometimes called opiates) are medicines used to treat severe pain. Diamorphine is a type of strong opioid. It is used in particular to treat pain after a surgical operation and pain caused by cancer. It may also be used following a heart attack, or for breathlessness caused by fluid in the lungs. It works on your nervous system and brain to reduce the amount of pain you feel.
