Painkiller

A medicine used to reduce or relieve pain.

“Painkiller” is a general, everyday term rather than the name of one specific class of medicine. It can refer to medicines such as acetaminophen (paracetamol), nonsteroidal anti-inflammatory drugs (NSAIDs), or opioid medicines.

Different painkillers work through different mechanisms and have different benefits, risks, and appropriate uses.

QUICK FACT

A painkiller may reduce pain without treating the underlying cause of the pain.

COMMONLY CONFUSED WITH
