Nurofen Fasttabs (Ibuprofen)

Ibuprofen, an NSAID, alleviates symptoms by inhibiting inflammatory pathways associated with various painful and febrile conditions.

• Headache: reduces pain intensity and associated discomfort.
• Fever: lowers elevated body temperature to normal range.
• Musculoskeletal pain: eases inflammation and soreness in joints and muscles.
• Toothache: diminishes dental pain and swelling.
• Menstrual cramps: relieves uterine cramping and associated discomfort.

• Ibuprofen exerts its therapeutic effect through reversible inhibition of cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes. By blocking these enzymes, the conversion of arachidonic acid to prostaglandins is reduced, leading to decreased synthesis of mediators that cause pain, fever, and inflammation. The inhibition is dose‑dependent and occurs throughout the body after oral absorption. The reduced prostaglandin levels diminish sensitization of nociceptors and lower the hypothalamic set‑point for temperature.

Ibuprofen may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or mild abdominal pain.
• Headache: transient mild headache.
• Dizziness: occasional light‑headed feeling.
• Rash: mild skin irritation or itching.

Serious or Rare Side Effects

• Gastrointestinal bleeding: ulceration or hemorrhage in the stomach or intestines.
• Severe allergic reaction: anaphylaxis, angioedema, or widespread rash.
• Liver injury: elevated liver enzymes or hepatitis.
• Kidney impairment: reduced renal function or acute kidney injury.

When using ibuprofen, consider the following precautions to minimize risk.

• Assess gastrointestinal risk: avoid in patients with active ulcers or a history of GI bleeding.
• Monitor renal function: use caution in individuals with kidney disease or dehydration.
• Evaluate cardiovascular status: limit use in patients with established heart disease or high thrombotic risk.
• Check for hypersensitivity: do not use if known allergy to ibuprofen or other NSAIDs.
• Use lowest effective dose: employ the minimal dose for the shortest duration needed.
• Store at ambient temperature: keep tablets in the original packaging, protect from moisture and heat.

Ibuprofen can interact with several medicines; awareness of these interactions helps ensure safe use.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• Other NSAIDs or COX‑2 inhibitors: additive gastrointestinal toxicity.
• High‑dose aspirin: heightened renal toxicity and reduced antiplatelet effect.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may diminish renal function when combined.
• Lithium: ibuprofen can raise serum lithium concentrations.
• Methotrexate: reduced clearance may increase toxicity.
