What is Ibuprofen?
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to relieve pain, reduce inflammation, and lower fever. It's available over-the-counter and by prescription in various strengths.
Ibuprofen works by blocking the production of prostaglandins, chemicals in the body that cause inflammation, pain, and fever. It's effective for headaches, muscle aches, arthritis, menstrual cramps, and minor injuries.
Dosage Guidelines
Proper ibuprofen dosing depends on age, weight, and the condition being treated:
| Age Group | Dose per Weight | Max Single Dose | Max Daily Dose |
|---|---|---|---|
| Children (6 months - 12 years) | 5-10 mg/kg every 6-8 hours | 400 mg | 40 mg/kg (max 1200 mg) |
| Adults (12+ years) | 200-400 mg every 4-6 hours | 400 mg (OTC) | 1200 mg (OTC) / 3200 mg (Rx) |

Frequently Asked Questions

- Ibuprofen is generally safe for infants 6 months and older when dosed correctly by weight. For babies under 6 months, consult a pediatrician before giving any medication.
- What's the difference between ibuprofen and acetaminophen?
