Paracetamol B. Braun (Paracetamol)

• Paracetamol B. Braun is an intravenous analgesic/antipyretic used to manage pain and fever.
• Pain: rapid relief of mild to moderate acute pain, such as musculoskeletal injury, dental pain, or postoperative discomfort.
• Fever: effective reduction of elevated body temperature caused by infection, inflammation, or other febrile conditions.
• Postoperative analgesia: provides controlled analgesia after surgical procedures, helping to improve patient comfort and facilitate early mobilization.
• Headache: alleviates tension‑type headache and can be used for mild migraine attacks when other therapies are unsuitable.

• Paracetamol exerts its analgesic and antipyretic actions primarily by inhibiting cyclooxygenase (COX) enzymes in the central nervous system, which reduces the synthesis of prostaglandins involved in pain signaling and thermoregulation. The drug’s weak peripheral COX inhibition and central activity lower the pain threshold and reset the hypothalamic temperature set‑point, producing fever reduction without significant anti‑inflammatory effects.

Paracetamol administered intravenously may be associated with several adverse reactions, ranging from common, mild events to rare but serious conditions.

Common Side Effects

• Injection site pain: mild discomfort at the infusion site.
• Nausea: transient feeling of queasiness.
• Transient hypotension: brief drop in blood pressure during rapid infusion.
• Elevated liver enzymes: mild increase in transaminases without clinical symptoms.

Serious or Rare Side Effects

• Anaphylaxis: severe allergic reaction with rash, bronchospasm, or circulatory collapse.
• Severe hepatotoxicity: acute liver injury, especially with overdose or pre‑existing liver disease.
• Blood dyscrasias: rare cases of thrombocytopenia or leukopenia.

• When using Paracetamol B. Braun, clinicians should observe several safety measures to minimize risk.
• Dose adjustment: modify dose in patients with hepatic impairment.
• Renal function: monitor renal status, especially in prolonged therapy.
• Concurrent hepatotoxic drugs: avoid or use with caution when combined with other liver‑affecting medications.
• Allergy history: assess for prior hypersensitivity to paracetamol or related compounds.
• Pregnancy and lactation: consider potential risks; use only if clearly indicated.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Paracetamol can interact with other medicines, affecting its metabolism or increasing toxicity.

Major Interactions (Avoid)

• Warfarin: increased anticoagulant effect, monitor INR closely.
• Isoniazid: heightened risk of hepatotoxicity when combined.

Moderate Interactions (Monitor Closely)

• Alcohol: additive liver stress, advise limited consumption.
• Other hepatotoxic agents (e.g., certain antiepileptics): monitor liver function tests.
• Enzyme inducers (e.g., carbamazepine, rifampicin): may reduce paracetamol plasma levels.
