Ibuprofen: Uses, Dosage, Side Effects, Essential Guide
Comprehensive guide to ibuprofen (Brufen, Calprofen, Nurofen): uses, dosage, side effects, and safety for pain relief and inflammation.
Ibuprofen is a widely used non-steroidal anti-inflammatory drug (NSAID) available over-the-counter under brand names like Brufen, Calprofen, and Nurofen. It effectively relieves mild to moderate pain, reduces fever, and eases inflammation associated with various conditions.
About ibuprofen tablets, capsules, gel, and spray
Ibuprofen comes in multiple forms including tablets, capsules, oral suspensions, gels, and sprays to suit different needs. Tablets and capsules are standard for oral use, while gels and sprays provide targeted topical relief for muscle or joint pain. Oral suspensions are ideal for children or those who struggle with pills. Always take oral forms with food or milk to minimize stomach irritation.
Key facts about ibuprofen
- Ibuprofen belongs to the NSAID class and works by inhibiting cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin production that causes pain, inflammation, and fever.
- Effects typically begin within 20-30 minutes, peaking at 1-2 hours, and lasting 4-6 hours.
- Common brands include Brufen, Calprofen (for children), and Nurofen.
- Not suitable for everyone; contraindicated in those with active peptic ulcers, severe heart failure, or allergies to NSAIDs.
- Maximum daily dose for adults is 1200 mg without medical advice; higher doses require supervision.
What is ibuprofen used for?
Ibuprofen treats a range of conditions by targeting pain and inflammation. Common uses include:
- Dental pain: Effective for toothaches and post-dental procedure discomfort.
- Period pain: Reduces menstrual cramps by decreasing uterine prostaglandins.
- Migraine: Alleviates headache pain and associated symptoms.
- Colds and flu: Lowers fever and relieves body aches.
- Backache and rheumatoid arthritis: Manages chronic joint inflammation and stiffness.
- Sprains, strains, and sports injuries: Reduces swelling and pain.
- Gout and other inflammatory conditions.
It is also used in cystic fibrosis to reduce lung inflammation and for orthostatic hypotension in select cases.
How does ibuprofen work?
Ibuprofen is a non-selective COX inhibitor. COX enzymes produce prostaglandins, which promote inflammation, pain, and fever at injury sites. By blocking COX-1 and COX-2, ibuprofen decreases prostaglandin levels, providing analgesic, antipyretic, and anti-inflammatory effects. COX-1 inhibition contributes to gastrointestinal side effects like ulcers. Pain relief involves both peripheral and central nervous system actions.
When not to take ibuprofen (before taking ibuprofen – warnings)
Avoid ibuprofen if you have:
- Active or history of peptic ulcers or gastrointestinal bleeding.
- Severe heart failure, kidney, or liver disease.
- Asthma triggered by NSAIDs (aspirin-sensitive).
- Third trimester pregnancy (risk of fetal harm).
- History of allergic reactions to ibuprofen or other NSAIDs.
High doses (2400 mg/day) may increase risk of heart attack or stroke. Use cautiously with blood thinners, diuretics, or other medications.
