Ibuprofene Pharmeg (Ibuprofen)

Ibuprofen is an NSAID that reduces pain, fever and inflammation by inhibiting prostaglandin synthesis.

• Pain: alleviates mild to moderate acute or chronic pain such as headache, dental or musculoskeletal discomfort.
• Fever: lowers elevated body temperature associated with infectious or inflammatory processes.
• Inflammation: reduces swelling and redness in conditions like arthritis or soft‑tissue injury.

• Ibuprofen inhibits both cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. This reduction in prostaglandin synthesis diminishes peripheral sensitization of nociceptors, lowers the hypothalamic set‑point for temperature, and limits inflammatory mediators, resulting in analgesic, antipyretic and anti‑inflammatory actions.

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

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia or abdominal pain.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Rash or mild skin irritation.
• Elevated blood pressure.
• Mild renal function changes.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding.
• Severe renal impairment or acute kidney injury.
• Anaphylactic or severe hypersensitivity reactions.
• Cardiovascular events such as myocardial infarction or stroke.
• Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Significant hepatic enzyme elevation.

Before initiating ibuprofen therapy, consider the following safety measures.

• Assess renal function: adjust use in patients with impaired kidney function.
• Evaluate gastrointestinal risk: use with food or gastro‑protective agents in high‑risk individuals.
• Review cardiovascular history: exercise caution in patients with heart disease or hypertension.
• Check for NSAID allergy: avoid if a hypersensitivity to ibuprofen or other NSAIDs is known.
• Use the lowest effective dose for the shortest duration necessary.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Ibuprofen can interact with several medicines; some require avoidance while others need close monitoring.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: heightened risk of ulceration or bleeding.
• Lithium: potential for increased lithium levels.
• ACE inhibitors or ARBs: may reduce renal perfusion.

Moderate Interactions (Monitor Closely)

• Diuretics: possible reduction in antihypertensive effect.
• Methotrexate: decreased clearance leading to toxicity.
• Selective serotonin reuptake inhibitors (SSRIs): modest increase in bleeding risk.
• Oral hypoglycemics: may affect blood glucose control.
• Antihypertensive agents: monitor blood pressure for additive effects.
