Codeine

Codeine is an opioid (opiate or narcotic) similar to morphine although not as strong. It is used for treating moderate pain and may also be prescribed for persistent dry coughs or to help control episodes of diarrhea.

Opiates work by binding to opioid receptors in the brain which reduce the patients perception of pain, reaction to pain and to increase tolerance of pain.

Codeine is available from your Doctor via a prescription. In the UK, it may be bought over the counter in pharmacies for short term pain relief. In this case it is known as Co-codamol. Codeine is also available in combination with other painkillers such as paracetamol.

Opioids taken for extended periods can result in dependence 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.
