Relieving the Pain
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing inflammation and pain. Over-the-counter tablets can be taken every four to six hours, as per the label's directions, but there's a limit to how many you can take per day.
The current recommendations for ibuprofen are to limit daily use to no more than 30 days. Dosing can range from 400 mg to 800 mg up to 4 times a day, with a daily maximum of 3200 mg per day. Above this limit, the negative effects of COX inhibition begin to outweigh the desired benefits of decreased discomfort and pain.
Because ibuprofen has a strong anti-inflammatory effect, it is more effective than paracetamol at controlling certain types of pain, including rheumatoid arthritis, period pain, and muscular injuries.
5. Can I take painkillers on an empty stomach? Ibuprofen, aspirin and other NSAIDs (non-steroidal anti-inflammatory drugs) can irritate the stomach lining, so it is best to take them with food, or a glass of milk. Paracetamol doesn't irritate the stomach lining so it won't matter if you haven't eaten.
Paracetamol works similarly to ibuprofen by blocking the production of prostaglandins and COX enzymes in the body - chemicals that promote pain, inflammation and fever. However, unlike ibuprofen that is primarily metabolised in the kidneys, paracetamol is processed in the liver.
Ibuprofen (Advil) and naproxen (Aleve) are both NSAID pain relievers that are fast and effective at providing pain relief, reducing inflammation, and fighting a fever. Ibuprofen works in as little as 20 minutes, whereas naproxen needs about an hour to take effect.

The medicine travels throughout the body and binds to the lock (receptor) if it fits. For example, Advil contains ibuprofen, which is a pain medication. The ibuprofen will latch onto any pain receptors that it comes across as it flows by. Only after it binds to this target can the drug perform its job.
Although acetaminophen and ibuprofen both relieve pain, they work in different ways—and on different kinds of pain. Acetaminophen works by blocking pain receptors in the brain. It will relieve pain and reduce fever, but it doesn't act on pain caused by inflammation. Ibuprofen blocks pain and reduces inflammation.
Giving paracetamol with other painkillers
Ibuprofen is the only safe painkiller to give children alongside paracetamol. However, do not give paracetamol and ibuprofen at the same time. You need to give these medicines 1 at a time (unless your child's doctor or nurse gives you different instructions).
