Codeine for pain relief

About codeine

What is codeine used for?

Codeine is a type of opioid (a strong painkiller) that is used to treat mild-to-moderate types of pain. It can be particularly useful when painkillers such as paracetamol och ibuprofen have not been effective.

How does codeine work?

Codeine works by binding to certain tiny areas, called opioid receptors, in your central nervous system (brain and spinal cord). This leads to a decrease in the way you feel pain and your reaction to pain.

Where can you get codeine from?

Codeine is available with a prescription from a doctor. It is also included in some pain relief medicines you can buy directly from a pharmacy without a prescription. One example is co-codamol, which contains codeine combined with paracetamol.

Codeine is also combined with the anti-inflammatory medicine ibuprofen in some over-the-counter products.

• Illamående.

• Kräkningar.
