- Paracetamol: Used to treat headaches and most non-nerve pains, side effects are not common and this dose can be taken regularly for long periods, but overdosing can cause serious side effects; if the pain lasts for more than three days, see your GP
- Ibuprofen: Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, diclofenac and naproxen, seem to work better for arthritis or an injury. They should not be used for a long period unless you have inflammation. If you take them for long periods, there’s an increased risk of stomach upset, bleeding, and kidney and heart problems
- Aspirin: Produces the same type of side effects as other NSAIDs, but is not as effective as a painkiller, which means it’s not usually prescribed for pain – dangerous for children under 16.
