Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce fever, and decrease inflammation in children and adults. It works by inhibiting prostaglandin production, making it effective for conditions such as headaches, toothaches, minor injuries, and symptoms of colds or flu. Available in liquid suspensions and chewable tablets, ibuprofen formulations are age- and weight-appropriate, with dosing based on weight rather than age. It is generally safe for children aged three months and older weighing at least 5 kg, but not recommended for infants under three months without medical guidance. Use in children should follow label instructions precisely, with caution regarding formulation suitability—some products are intended only for children 7 or 12 years and older. Ibuprofen should not be used long-term or at high doses due to risks of cardiovascular events, gastrointestinal bleeding, kidney impairment, and allergic reactions. It may interact with other medications, including anticoagulants, blood pressure drugs, and corticosteroids. Use during pregnancy, especially in the third trimester, is discouraged due to fetal risks. The medication treats symptoms only, not underlying causes, and should not replace medical evaluation for persistent or worsening symptoms. Serious side effects—such as black stools, severe abdominal pain, rash, swelling, or breathing difficulties—require immediate medical attention. Accurate dosing and adherence to duration limits are essential to avoid toxicity. Ibuprofen is available over-the-counter but requires responsible use to minimize risks, particularly in vulnerable populations.
