What are they?

Simple non-opioid analgesics are the most common form of analgesic. We usually include non-steroidal anti-inflammatory drugs (NSAIDs) in this category.

What are they used for?

You can use them for mild to moderate pain, for example headaches, injuries and osteoarthritis, or as an addition to stronger painkillers. You shouldn’t use them at high doses for long-term pain.

Where do I get them from?

You can buy them over the counter at supermarkets and chemists, although you can only get some NSAIDs on prescription from your doctor. Paracetamol and some NSAIDs are available as tablets, liquids, creams and gels, and suppositories.

What are the side-effects?

Paracetamol, the most common simple non-opioid analgesic, has few side-effects, but high doses can cause liver damage. NSAIDs have more side-effects, particularly on your stomach.
