Nurofen Rapid (Ibuprofen)

Ibuprofen, an NSAID, reduces pain and inflammation by inhibiting cyclooxygenase enzymes.

• Headache: provides relief by decreasing prostaglandin‑mediated pain signals.
• Musculoskeletal pain: eases aches and stiffness associated with strains, sprains and arthritis.
• Fever: lowers elevated body temperature through central thermoregulatory effects.
• Dental pain: alleviates discomfort after dental procedures.
• Inflammatory conditions: diminishes swelling and redness in minor inflammatory disorders.

• Ibuprofen reversibly inhibits both cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, leading to reduced conversion of arachidonic acid to prostaglandins. The decrease in prostaglandin synthesis diminishes peripheral sensitisation of nociceptors, lowers fever set‑points in the hypothalamus, and limits inflammatory exudate formation.

Adverse reactions may range from mild to severe and should be monitored.

Common Side Effects

• Nausea: occasional upset stomach after dosing.
• Dyspepsia: indigestion or heartburn.
• Headache: transient headache in some users.
• Dizziness: mild vertigo or light‑headedness.
• Rash: mild skin irritation or itching.
• Diarrhoea: loose stools in a minority of patients.

Serious or Rare Side Effects

• Gastrointestinal bleeding: potentially life‑threatening ulceration.
• Peptic ulcer perforation: severe abdominal pain requiring urgent care.
• Renal impairment: reduced kidney function, especially with prolonged use.
• Severe allergic reaction: anaphylaxis, angioedema, or bronchospasm.
• Hepatotoxicity: elevated liver enzymes or hepatitis.
• Cardiovascular events: increased risk of heart attack or stroke in high‑risk individuals.

Before using Nurofen Rapid, consider the following safety measures.

• Age restriction: use only in individuals for whom the prescriber determines appropriate dosing.
• Hypersensitivity: avoid if known allergy to ibuprofen or other NSAIDs.
• Gastrointestinal risk: caution in patients with a history of ulcers or bleeding.
• Renal function: monitor kidney health in those with pre‑existing renal disease.
• Concomitant anticoagulants: assess bleeding risk when taken with warfarin or similar agents.
• Alcohol consumption: limit intake as it may increase gastrointestinal irritation.
• Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Ibuprofen can interact with several medicines; awareness helps prevent complications.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: heightened ulcer risk.
• Lithium: elevated lithium serum levels.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect.
• Diuretics: potential for reduced renal perfusion.
• Selective serotonin reuptake inhibitors (SSRIs): increased bleeding tendency.
• Oral contraceptives: may slightly reduce efficacy.
• Beta‑blockers: monitor blood pressure control.
