What Is Ibuprofen?
Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) widely used to relieve pain, reduce fever, and decrease inflammation. It is available over the counter in many countries and is sold under brand names such as Advil, Motrin, and Nurofen, among others.
Despite being readily available, ibuprofen carries real risks when misused — particularly with the stomach, kidneys, and cardiovascular system. Getting the dose right is essential.
How Ibuprofen Works
Ibuprofen works by blocking enzymes called COX-1 and COX-2, which produce prostaglandins — chemicals responsible for pain, inflammation, and fever. By reducing prostaglandin production, ibuprofen relieves these symptoms.
Adult Dosage Guidelines
| Use | Typical Dose | Frequency | Max Daily Dose (OTC) |
|---|---|---|---|
| Mild to moderate pain | 200–400 mg | Every 4–6 hours | 1,200 mg |
| Fever | 200–400 mg | Every 4–6 hours | 1,200 mg |
| Prescription strength | 400–800 mg | Every 6–8 hours | 3,200 mg (under medical supervision) |
OTC maximum for self-medication is generally 1,200 mg per day. Higher doses require a prescription and medical oversight.
Children's Dosage Guidelines
For children, ibuprofen is dosed based on body weight, not age. The standard pediatric dose is:
- 5–10 mg per kilogram of body weight per dose
- Given every 6–8 hours as needed
- Maximum of 4 doses in 24 hours
- Do not use in infants under 3 months or under 5 kg without medical advice
Always use a proper measuring device (oral syringe or dosing cup) — never a kitchen spoon. Shake liquid formulations well before use.
Key Safety Rules
- Take with food or milk to reduce stomach irritation.
- Stay hydrated — ibuprofen can affect kidney function, especially if you're dehydrated.
- Do not exceed the maximum dose or take more frequently than directed.
- Avoid long-term use without medical supervision.
- Do not combine with other NSAIDs (e.g., naproxen, aspirin) — this increases the risk of side effects.
Who Should Avoid Ibuprofen?
Ibuprofen may not be suitable for everyone. Speak with a doctor before use if you:
- Have a history of stomach ulcers or GI bleeding
- Have kidney or liver disease
- Have heart disease or high blood pressure
- Are pregnant (especially in the third trimester — ibuprofen is generally contraindicated)
- Are taking blood thinners, corticosteroids, or other NSAIDs
- Have a known allergy to aspirin or other NSAIDs
Signs of Ibuprofen Overdose
Taking too much ibuprofen can be serious. Signs of overdose include:
- Severe stomach pain, nausea, or vomiting
- Drowsiness or confusion
- Black or tarry stools (sign of GI bleeding)
- Ringing in the ears
- Difficulty breathing
If you suspect an overdose, seek emergency medical care immediately or contact your local poison control center.
Ibuprofen vs. Acetaminophen (Paracetamol): Which to Choose?
Both are effective for pain and fever, but they work differently:
- Ibuprofen is preferred when inflammation is a key component (e.g., sprains, arthritis flares, dental pain).
- Acetaminophen is gentler on the stomach and is often preferred for those with GI issues, kidney concerns, or pregnancy.
