Medical professionals and regulatory agencies are issuing warnings regarding the risks associated with the misuse of common over-the-counter painkillers, including ibuprofen, paracetamol, diclofenac, and naproxen.

Initial guidance focused on ibuprofen, noting that improper use can lead to stomach bleeding, kidney damage, and increased sun sensitivity. Experts recommended a maximum daily dose of 1,200 mg for adults and cautioned against use for more than 10 consecutive days for pain or three days for fever without supervision. High-risk groups identified include pregnant women, infants under six months, and individuals with heart, liver, or kidney disease.

Subsequent warnings expanded to include other non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol. Professionals highlighted that diclofenac and naproxen also pose risks of kidney damage and stomach ulcers, while excessive paracetamol consumption can cause liver damage. General medical advice has emphasized limiting self-administered medication to no more than four consecutive days without consultation, with a broader guideline of using such drugs no more than ten days per month to avoid dependency and rebound headaches.
