Morphine

Morphine is a type of painkiller used for moderate to severe pain. It is classified as a strong opioid analgesic (also sometimes called narcotics).

Morphine is used to relieve moderate to severe pain and also in easing severe coughs. It works by affecting the nerves and brain to decrease the pain you feel or the urge to cough.

Opioids (opiates) are chemicals which bind to opioid receptors in the central nervous system. They reduce the perception of pain, the reaction to pain and also increase the patients tolerance of pain. Codeine is another form of opiate.

Opioids taken for extended periods can result in dependance as they can result in feelings of euphoria and withdrawal symptoms upon stopping the medication. This has resulted in the use of opioids for recreational purposes.

In the UK morphine is only available via a prescription from your Doctor or whilst admitted to hospital.

Morphine is available in the form or tablets, capsules or a solution (liquid). There are various brands of each form of morphine medication and the directions for usage will vary slightly between each type. Make sure you follow the instructions given to you by your Doctor.
