Sevredol tablets (morphine)

How does it work?

Sevredol tablets contain the active ingredient morphine sulphate, which is a type of medicine called an opioid painkiller.

Opioid painkillers work by mimicking the action of naturally occurring pain-reducing chemicals called endorphins. Endorphins are found in the brain and spinal cord and reduce pain by combining with opioid receptors.

Morphine mimicks the action of endorphins by combining with the opioid receptors in the brain and spinal cord. This blocks the transmission of pain signals sent by the nerves to the brain. Therefore, even though the cause of the pain may remain, less pain is actually felt.

Morphine is used to relieve severe pain, for example associated with cancer or severe injury.

What is it used for?

Severe pain.

Warning!

This medicine may cause drowsiness. If affected do not drive or operate machinery. Alcohol should be avoided.

If this medicine is taken for prolonged periods of time, the body can become tolerant to it and it may become less effective at relieving pain. This means that with time, higher doses may be needed to control pain. With prolonged use the body may also become dependent on the medicine. As a result, withdrawal symptoms can occur if the medicine is stopped suddenly. For this reason, when a person no longer needs this medicine it may be necessary to reduce treatment gradually to avoid withdrawal symptoms.
