Junior (Ibuprofen)

Ibuprofen acts systemically to manage conditions involving pain, fever, and inflammation.

• Pain relief: reduces mild to moderate pain such as headache, toothache, or musculoskeletal discomfort.
• Fever reduction: lowers elevated body temperature associated with infections or inflammatory states.
• Inflammation reduction: alleviates swelling and redness in conditions like minor injuries or arthritis.

• Ibuprofen reversibly inhibits cyclooxygenase‑1 and cyclooxygenase‑2 (COX‑1/COX‑2), enzymes responsible for converting arachidonic acid into prostaglandins. By decreasing prostaglandin synthesis, it reduces the sensitization of nociceptors, lowers the hypothalamic set‑point for temperature, and diminishes vascular permeability, thereby providing analgesic, antipyretic, and anti‑inflammatory effects.

Adverse reactions may occur with ibuprofen use and are categorized by frequency and severity.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or mild abdominal pain.
• Headache: transient mild to moderate headache.
• Dizziness: occasional light‑headedness.
• Rash: mild skin erythema or itching.
• Elevated blood pressure: modest rise in systolic or diastolic values.

Serious or Rare Side Effects

• Gastrointestinal bleeding: melena, hematemesis, or severe abdominal pain.
• Renal impairment: reduced urine output or elevated creatinine.
• Hepatotoxicity: jaundice or abnormal liver enzymes.
• Severe allergic reactions: angioedema, bronchospasm, or anaphylaxis.
• Cardiovascular events: increased risk of myocardial infarction or stroke in high‑risk patients.

Before using ibuprofen, consider the following safety measures.

• Assess renal function: avoid use in patients with severe kidney disease.
• Evaluate gastrointestinal risk: use cautiously in those with ulcer history or bleeding disorders.
• Monitor cardiovascular status: limit use in patients with uncontrolled hypertension or heart disease.
• Review concomitant medications: avoid combining with other NSAIDs, anticoagulants, or corticosteroids without medical guidance.
• Pregnancy and lactation: consult a healthcare professional before use during pregnancy or breastfeeding.
• Store at ambient temperature: keep below 25°C in the original packaging, protect from moisture and direct sunlight.

Ibuprofen can interact with several drug classes, influencing efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Selective COX‑2 inhibitors: additive gastrointestinal toxicity.
• High‑dose aspirin: heightened renal and gastrointestinal adverse effects.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect and renal function.
• Diuretics: may diminish diuretic efficacy and increase renal stress.
• Lithium: ibuprofen can raise serum lithium levels, requiring monitoring.
