About the product
Codeine is one of the medicines known as opioid analgesics or painkillers, which is less potent than morphine. Its exact mechanism of action has not been discovered but its action is thought to be due to its conversion to morphine. In a similar way to morphine, it attaches to opioid receptors in the brain that transmit pain sensations. By acting on the nervous system, codeine also reduces gut movements (thus stopping diarrhoea) and suppresses the reflex causing cough. It is often used in combination with paracetamol or other painkillers.
