Paracetamol/ Ibuprofen Rontis (Ibuprofen, Paracetamol)

Paracetamol/ Ibuprofen Rontis combines two analgesic‑antipyretic agents that act on inflammatory and temperature‑regulation pathways.

• Mild to moderate pain: provides relief of headache, dental pain, musculoskeletal discomfort and dysmenorrhoea.
• Fever in adults and children: reduces elevated body temperature associated with viral or bacterial infections.
• Post‑operative or trauma pain: assists in managing pain after minor surgical procedures or injuries.

• Ibuprofen inhibits cyclo‑oxygenase (COX‑1 and COX‑2) enzymes, decreasing prostaglandin synthesis that mediates inflammation, pain and fever. Paracetamol acts centrally to inhibit a variant of the COX enzyme and modulates the serotonergic pathway, lowering the hypothalamic set‑point for temperature and providing analgesia. The combined effect offers broader pain relief and antipyretic action than either agent alone.

Paracetamol/ Ibuprofen Rontis may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects

• Gastro‑intestinal discomfort: nausea, dyspepsia or mild abdominal pain.
• Headache: transient headache may occur.
• Dizziness or light‑headedness.
• Skin reddening: mild flushing or erythema.
• Elevated liver enzymes: mild, transient rise in hepatic markers.

Serious or Rare Side Effects

• Gastro‑intestinal ulceration or bleeding.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Hepatic failure or significant liver injury.
• Renal impairment or acute kidney injury.
• Anaphylaxis: rapid onset of swelling, airway compromise or hypotension.

When prescribing Paracetamol/ Ibuprofen Rontis, clinicians should consider patient‑specific factors and monitor for adverse events.

• Renal function: assess baseline kidney function, especially in the elderly or dehydrated patients.
• Hepatic health: avoid in patients with active liver disease or chronic alcohol use.
• Cardiovascular risk: use cautiously in patients with hypertension or heart failure.
• Gastro‑intestinal history: avoid in individuals with a history of ulcers or bleeding.
• Concomitant NSAIDs: do not combine with other NSAID products to prevent excess toxicity.
• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Paracetamol/ Ibuprofen Rontis can interact with several medication classes, requiring careful review before co‑administration.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• High‑dose corticosteroids: heightened gastrointestinal ulcer risk.
• Selective serotonin reuptake inhibitors (SSRIs): additive bleeding tendency.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce renal perfusion, especially in hypovolaemic patients.
• Diuretics: heightened risk of renal insufficiency.
• Lithium: ibuprofen may raise serum lithium levels.
• Methotrexate: ibuprofen can reduce renal clearance, increasing toxicity.
