Junifen Sabor Limon (Ibuprofen)

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

• Pain: Relieves mild to moderate nociceptive pain such as headache, dental or musculoskeletal discomfort.
• Fever: Lowers elevated body temperature associated with infectious or inflammatory processes.
• Inflammation: Decreases swelling and redness in conditions like sprains or soft‑tissue injuries.
• Arthritis: Alleviates joint pain and stiffness in osteoarthritis and rheumatoid arthritis.

• Ibuprofen exerts its effect by reversibly inhibiting the cyclooxygenase enzymes COX‑1 and COX‑2, which blocks the conversion of arachidonic acid to prostaglandins. The reduction in prostaglandin synthesis diminishes inflammation, lowers fever, and attenuates pain signaling pathways throughout the body.

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

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.
• Fluid retention or edema.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Acute renal impairment or failure.
• Severe allergic reactions including anaphylaxis.
• Hepatotoxicity with elevated liver enzymes.
• Cardiovascular events such as myocardial infarction or stroke.
• Blood dyscrasias like thrombocytopenia.

When using ibuprofen, consider the following safety measures.

• Assess renal function: monitor patients with existing kidney disease.
• Avoid in active peptic ulcer disease: consider alternative therapy.
• Use lowest effective dose for shortest duration: minimize risk of GI and cardiovascular events.
• Caution in elderly: increased susceptibility to adverse effects.
• Avoid concomitant use with other NSAIDs or anticoagulants unless medically indicated.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Ibuprofen can interact with several medication classes; awareness helps prevent complications.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Selective serotonin reuptake inhibitors (SSRIs): heightened gastrointestinal bleeding.
• Corticosteroids: additive ulcer risk.
• Lithium: increased serum lithium concentrations.
• ACE inhibitors or ARBs: may reduce renal function.

Moderate Interactions (Monitor Closely)

• Diuretics: may affect renal clearance of ibuprofen.
• Methotrexate: reduced excretion leading to potential toxicity.
• Beta‑blockers: possible attenuation of antihypertensive effect.
• Cyclosporine: increased risk of nephrotoxicity.
• Allopurinol: potential hypersensitivity reactions.
