Ibuprofen is a commonly available over-the-counter painkiller that you can pick up from nearly any pharmacy or supermarket. Known for its effectiveness, it helps relieve various aches, pains, inflammation, and even symptoms linked to colds, flu, or coronavirus. However, it’s important to remember that ibuprofen isn’t suitable for everyone. The NHS advises that people in eight key situations should avoid this anti-inflammatory (NSAID) medication, and anyone unsure should check with a pharmacist or doctor.Ibuprofen Warning: Who Should Avoid It?The NHS advises the following people should avoid taking ibuprofen:Anyone who has had an allergic reaction to ibuprofen, aspirin, or another NSAIDThose with a stomach ulcer or a history of ulcersPeople with asthma or allergies (such as hay fever)Individuals with chickenpoxAnyone with heart, liver, or kidney problemsPeople with blood clotting issuesAnyone who has previously had a strokeThose who are pregnant or trying to conceivePeople who have had allergic reactions to ibuprofen, aspirin, or similar NSAIDs like naproxen should avoid it entirely, as should expectant mothers. Those with kidney problems, asthma, or a history of stomach ulcers should always seek medical advice before using ibuprofen, including topical forms.The NHS adds: “How you take your medicine and the dose you use depends on the type of ibuprofen and how much it contains. Always read the packet or leaflet that comes with your medicine. Ask a pharmacist or doctor for guidance if you’re unsure about how to take it or encounter any problems. If a doctor prescribes ibuprofen, follow their instructions carefully.”Typically, adults can take one or two 200mg ibuprofen tablets or capsules up to three times a day, leaving at least six hours between doses. In some cases, a higher dose may be prescribed, but only under a doctor’s supervision.Medicines That Require Extra CautionIf you’re taking certain medications, consult a doctor before using ibuprofen.

Long-term conditions, such as rheumatoid arthritis, may require longer courses.”Who Needs to Consult a Doctor Before Taking Paracetamol?Paracetamol isn’t suitable for everyone either. The NHS advises that certain groups should get medical guidance before taking it:People on certain medicationsAnyone who has had an allergic reaction to paracetamol or another medicineIndividuals with liver or kidney issuesPeople who regularly drink more than the recommended 14 units of alcohol per weekThose weighing less than 50kg (eight stone) may need a lower doseOfficial NHS guidance, as reported by the Mirror, states: “Most people aged 16 and over can take paracetamol.
