Ibuprofen Relonchem (Ibuprofen)

Ibuprofen acts on inflammatory pathways to relieve symptoms in several common conditions.

• Mild to moderate pain: provides analgesic relief for headaches, dental pain, musculoskeletal discomfort, and other acute pain states.
• Fever: reduces elevated body temperature by acting on the hypothalamic heat‑regulation center.
• Arthritis and other inflammatory conditions: decreases inflammation and associated discomfort in osteoarthritis, rheumatoid arthritis, and similar disorders.

• Ibuprofen exerts its therapeutic effect by reversibly inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes. This inhibition reduces the conversion of arachidonic acid to prostaglandins, thereby decreasing the synthesis of mediators that promote pain, fever, and inflammation throughout the body.

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

Common Side Effects

• Nausea: mild stomach upset or queasiness.
• Dyspepsia: indigestion or upper abdominal discomfort.
• Headache: transient head pain.
• Dizziness: feeling light‑headed or unsteady.
• Rash: mild skin irritation or redness.
• Diarrhoea: loose stools.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation: potentially life‑threatening bleeding in the stomach or intestines.
• Renal impairment: reduced kidney function, especially in at‑risk patients.
• Severe allergic reactions: anaphylaxis, angioedema, or Stevens‑Johnson syndrome.
• Hepatotoxicity: liver enzyme elevations or liver injury.
• Thrombocytopenia: low platelet count leading to bleeding tendencies.
• Cardiovascular events: increased risk of heart attack or stroke in susceptible individuals.

Before initiating therapy, consider the following safety measures.

• Assess gastrointestinal risk: evaluate history of ulcers, bleeding, or chronic NSAID use.
• Monitor renal function: especially in patients with pre‑existing kidney disease or dehydration.
• Avoid in third‑trimester pregnancy: risk of fetal complications and premature closure of the ductus arteriosus.
• Use the lowest effective dose: minimize exposure while achieving therapeutic benefit.
• Concurrent anticoagulant therapy: increase bleeding risk and may require closer monitoring.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Ibuprofen may interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Other NSAIDs (e.g., naproxen, diclofenac): additive gastrointestinal toxicity.
• High‑dose aspirin: increased risk of gastric ulceration and bleeding.
• Anticoagulants (warfarin, DOACs): heightened bleeding tendency.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce renal perfusion and impair kidney function.
• Diuretics (e.g., furosemide): potential for reduced renal clearance and electrolyte disturbances.
• Lithium: NSAIDs can raise lithium serum concentrations, risking toxicity.
