Nurofenxs (Ibuprofen)

Ibuprofen acts as an analgesic, antipyretic and anti‑inflammatory agent, providing relief across several common conditions.

• Pain: alleviates mild to moderate acute pain such as headache, toothache or musculoskeletal discomfort.
• Fever: reduces elevated body temperature associated with viral or bacterial infections.
• Osteoarthritis: improves joint pain and stiffness in chronic degenerative joint disease.
• Rheumatoid arthritis: lessens inflammatory pain and swelling in autoimmune joint disease.
• Dysmenorrhea: eases menstrual cramps and associated pelvic pain.

• Ibuprofen exerts its effect by reversibly inhibiting cyclo‑oxygenase (COX‑1 and COX‑2) enzymes, which catalyze the conversion of arachidonic acid to prostaglandins. By lowering prostaglandin synthesis, it diminishes peripheral sensitisation of nociceptors, reduces fever‑inducing hypothalamic set‑point changes, and limits inflammatory exudate formation. The inhibition is dose‑dependent and transient, allowing normal platelet function to recover between doses. This pharmacologic profile underlies its analgesic and antipyretic properties.

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

Common Side Effects

• Stomach upset: nausea, dyspepsia or abdominal discomfort.
• Headache: mild to moderate intensity.
• Dizziness: transient feeling of light‑headedness.
• Rash: mild skin irritation or erythema.
• Indigestion: heartburn or acid reflux.
• Liver injury: elevated transaminases or hepatitis.

Serious or Rare Side Effects

• Gastrointestinal bleeding: ulceration or hemorrhage in the stomach or intestines.
• Renal impairment: reduced kidney function or acute kidney injury.
• Cardiovascular events: increased risk of heart attack or stroke, especially with high‑dose or prolonged use.
• Severe allergic reaction: anaphylaxis with swelling, breathing difficulty, or hives.
• Liver injury: significant hepatic dysfunction in rare cases.
• Blood disorders: thrombocytopenia or leukopenia.

Before using ibuprofen, consider the following safety measures.

• Assess medical history: ensure no peptic ulcer, bleeding disorder, or severe heart failure.
• Check kidney function: avoid in chronic kidney disease or dehydration.
• Monitor cardiovascular risk: limit use if hypertension, coronary disease or prior stroke.
• Use lowest effective dose: smallest dose for shortest duration needed.
• Avoid other NSAIDs: do not combine with aspirin or other NSAIDs without advice.
• Pregnancy and breastfeeding: seek professional guidance; generally avoided in third trimester.
• Store at ambient temperature: keep below 25 °C in original pack, protected from moisture.

Ibuprofen can interact with several medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Antiplatelet agents (e.g., clopidogrel): additive bleeding risk.
• SSRIs: heightened gastrointestinal bleeding potential.
• ACE inhibitors or ARBs: may reduce renal protective effects and worsen kidney function.
• Lithium: ibuprofen can raise lithium serum levels, risking toxicity.

Moderate Interactions (Monitor Closely)

• Diuretics: may enhance renal impairment when combined.
• Methotrexate: ibuprofen can decrease clearance, increasing toxicity.
• Corticosteroids: combined use raises ulceration risk.
• Blood pressure medications: ibuprofen may blunt antihypertensive response.
• Oral hypoglycemics: possible alteration of blood glucose control.
