Ibuprofen is a painkiller available over the counter without a prescription. It’s one of a group of painkillers called non-steroidal anti-inflammatory drugs (NSAIDs) and can be used to: ease mild to moderate pain – such as toothache, migraine and period pain. The painkilling effect of ibuprofen begins soon after a dose is taken, but the anti-inflammatory effect can sometimes take up to 3 weeks to get the best results.
Ibuprofen shouldn’t be used to treat conditions that are mainly related to inflammation.
Don’t take more than the recommended dose if it isn’t relieving your symptoms.
