Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to relieve mild to moderate pain, reduce fever, and decrease inflammation. It is available over the counter in many countries and by prescription in higher strengths, and it is sold under brand names such as Advil and Motrin. It works by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), which decreases the synthesis of prostaglandins involved in pain, fever, and inflammation. Key points to know

• Uses: relief of headache, muscle aches, dental pain, menstrual cramps, arthritis symptoms, and fever. It can be used for short-term pain relief and to reduce inflammatory signs in various conditions.
• Dosing (adult): OTC packages typically provide 200 mg tablets; common dosing is 200–400 mg every 4–6 hours as needed, not exceeding 1200 mg in 24 hours without medical advice, though higher prescription-strength schedules exist. For children, dosing is weight-based and requires pediatric guidelines or a clinician’s instruction.
• Safety and risks: generally well tolerated at recommended doses but can cause stomach upset, ulcers, kidney effects, elevated blood pressure, and, rarely, allergic reactions. It may increase risk of gastrointestinal bleeding, especially with longer use or in combination with certain other medications (like anticoagulants or steroids). It can affect kidney function and should be avoided in advanced kidney disease. It should be used with caution in people with heart disease, high blood pressure, liver disease, or a history of stomach ulcers.
• Special considerations: avoid in the third trimester of pregnancy due to potential effects on the fetus and pregnancy complications; always consult a healthcare professional for use during pregnancy or if breastfeeding. Do not combine with alcohol in excess or with other NSAIDs unless instructed by a clinician.
• Interactions: potential interactions with anticoagulants (e.g., warfarin), other NSAIDs, certain antidepressants, blood pressure medications, and certain kidney or liver drugs. Always review your full medication list with a healthcare professional.
• Alternatives: acetaminophen (paracetamol) for pain or fever; other NSAIDs or non-drug approaches depending on the condition and risk factors.

If you’d like, specify:

• Your age or whether the request is for an adult or child
• The condition you’re treating (e.g., fever, headache, dental pain, menstrual cramps, arthritis)
• Any medical conditions you have (like kidney, liver, stomach ulcers, cardiovascular disease) or medications you’re taking
