Most anti-inflammatory drugs also have the ability to relieve fever and antiplatelet (anti-clotting) properties. Paracetamol has the ability to reduce fever, but has minimal anti-inflammatory effects and no effect on blood clotting. Paracetamol is the preferred option for fever and mild-to-moderate pain as it has fewer adverse effects.
NSAIDs, including aspirin, are indicated for:
- Mild-to-moderate pain due to inflammation and tissue injury

Paracetamol is indicated for:

Anti-inflammatories relieve pain and inflammation within the body by decreasing the production of pro-inflammatory chemicals known as prostaglandins. Prostaglandins are normally produced in response to tissue damage, and are known to play a major role in the processes of inflammation, pain and fever.
Paracetamol also works by reducing the synthesis of prostaglandins.
