Paracetamol and ibuprofen work in different ways, so a doctor or pharmacist may suggest using them together or alternating them to improve pain control for musculoskeletal pain. This is a common approach for short-term relief of sprains, strains, and back pain.
However, suitability depends on your individual health. Ibuprofen and other anti-inflammatories (NSAIDs) may not be appropriate if you have stomach ulcers, kidney problems, heart failure, uncontrolled high blood pressure, asthma triggered by painkillers, or if you are pregnant. Paracetamol is generally well tolerated but the total daily amount must never be exceeded, and it is found in many combination cold and flu products, so accidental double-dosing is a risk.
Do not exceed the doses stated on the packaging, and do not combine multiple products containing the same ingredient. Always confirm with a pharmacist or doctor before combining medicines, particularly if you take other prescriptions or have ongoing medical conditions. Seek advice if pain is severe or not controlled.
