NHS GP Dr Amir Khan has issued a warning to people who reach for ibuprofen immediately after an injury, stating that taking the painkiller too soon can prolong recovery. The familiar face on ITV's Lorraine and Good Morning Britain explained that while inflammation is often seen as negative, it is a crucial part of the body's healing process.
Why taking ibuprofen too soon can be harmful
Dr Khan discussed the topic on his No Appointment Necessary podcast, as reported by the Express. He said: "Now, the newer bit [of research] about ibuprofen is when you should take it. When you've sprained your ankle or broken a bone or something like that, remember I said that some inflammation is good. Your immune system responds, comes to the scene, and starts sorting things out and healing. If you take ibuprofen too soon in that process, that can hinder your healing time."
Ibuprofen works by blocking the body's production of prostaglandins, the chemicals that trigger pain, swelling, and fever. While this can provide relief, introducing the drug too early can force the body to work harder during healing.
Recommended waiting period
Dr Khan advises patients to wait at least two to three days before taking ibuprofen after an injury. He stated that his standard advice is "not to take [ibuprofen] within the first two or three days." Instead, paracetamol is typically safer to use straight after an injury, as it helps block pain signals without disrupting the body's natural healing process.
Paracetamol is recommended as a primary pain relief method to prevent discomfort from worsening and maintain mobility. The NHS states that paracetamol is generally safe for immediate use after an injury.
Potential side effects of ibuprofen
Like all medicines, ibuprofen can cause side effects, though not everyone experiences them. Common side effects from tablets, capsules, liquid, and granules include indigestion, stomach aches, nausea, vomiting, headaches, a rash, dizziness, diarrhoea, or constipation.
The NHS notes that you are less likely to experience side effects from ibuprofen gel or spray compared to tablets and capsules. The health service advises: "To reduce the risk of side effects, take the smallest dose you need for the shortest time you need it. Do not take ibuprofen tablets and capsules for more than 10 days unless advised to by a doctor. For other types of ibuprofen, check the packet or leaflet to see how long you can use it for. See a GP if your pain gets worse or does not go away."
Dr Khan's advice underscores the importance of allowing the body's natural inflammatory response to initiate healing before intervening with medication. For minor injuries, waiting a few days before using ibuprofen can lead to faster overall recovery.
