NHS GP Dr Amir Khan has issued a warning that taking ibuprofen too soon after an injury may actually slow down the healing process. The common painkiller, available in most UK supermarkets and pharmacies for under £1, is widely used to relieve mild to moderate pain, reduce inflammation, and lower fevers. However, Dr Khan suggests that people should wait longer before reaching for this medication.
Why Ibuprofen May Hinder Healing
Ibuprofen works by blocking the body's production of prostaglandins, chemicals that cause pain, swelling, and fever. While this provides relief, Dr Khan explains that some inflammation is beneficial for healing. 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."
Recommended Waiting Period
Dr Khan, known for his regular appearances on ITV's Lorraine and Good Morning Britain, discussed the issue on his No Appointment Necessary podcast. He advised patients with injuries like sprains or broken bones "not to take [ibuprofen] within the first two or three days." For immediate pain relief, paracetamol is generally safer as it blocks pain signals without interfering with the natural healing process. The NHS recommends paracetamol to prevent pain from escalating and help maintain mobility.
Side Effects of Ibuprofen
Like all medicines, ibuprofen can cause side effects, though not everyone experiences them. Common complaints from tablets, capsules, liquid, and granules include indigestion, stomach aches, nausea, vomiting, headaches, rash, dizziness, diarrhoea, or constipation. The NHS notes that side effects are less likely with ibuprofen gel or spray compared to oral forms. To reduce risks, the health service advises: "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, check the packet or leaflet for usage duration. See a GP if pain worsens or does not go away.
