What is it?

Pain medication, or painkillers, refer to drugs like paracetamol, aspirin, and codeine, as well as other drugs which are available with a prescription. They come mostly in tablet form and are usually taken with water, or dissolved in water. Paracetamol is also sold in syrup form for children. Their main uses are for headaches, colds, muscular pains and other pain from injuries.

How does it work?

Research has suggested that inflammatory processes may have a role in depression. Pain medication which reduces inflammation may therefore be of use in treating depression.

Is it effective?

There is no evidence that common pain medication such as aspirin or paracetamol have any effect on people's mood.

There is some evidence on the use of a specific anti-inflammatory pain medication, celecoxib, in the treatment of depression. Studies have found that people who were prescribed celecoxib in addition to standard antidepressant medication experienced a greater reduction in their depression symptoms than those who were prescribed only the antidepressant medication.

Are there any disadvantages?

Painkillers can cause side effects in some people and are toxic in high doses. If you take pain medication, ask your doctor or pharmacist it if might interfere with other medications or supplements you are taking. You should also talk with your doctor if your symptoms worsen or new ones develop.

Where do you get it?

Common painkillers are available from pharmacists without a prescription and are sold in most supermarkets.

Celecoxib is only available with a prescription from your doctor. 


Common pain medications are unlikely to be helpful for depression, but can help with headaches or other pains that may accompany depression. If severe pain or serious physical illness is causing depression, discuss this with your doctor.

Celecoxib appears to be a promising treatment for depression when combined with regular antidepressant medication.
