Paracetamol Fresenius Kabi (Paracetamol)

Paracetamol Fresenius Kabi is an analgesic and antipyretic that acts within the central nervous system to manage pain and fever.

• Post‑operative pain: Provides short‑term relief of moderate pain following surgery.
• Fever management: Reduces elevated body temperature in acute febrile states.
• Acute migraine: Helps alleviate headache intensity when oral agents are unsuitable.
• Cancer‑related pain: Contributes to multimodal analgesia for breakthrough pain in oncology patients.
• Severe traumatic injury : Controls pain and fever associated with major trauma.

• Paracetamol exerts its effect primarily by inhibiting cyclooxygenase enzymes in the central nervous system, especially COX‑2, which reduces prostaglandin synthesis. This action lowers the pain‑transmission threshold and produces antipyretic effects by acting on hypothalamic heat‑regulation centers. The exact peripheral mechanism remains less defined compared to non‑steroidal anti‑inflammatory drugs.

Paracetamol is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Nausea
• Mild skin rash
• Transient elevation of liver enzymes
• Headache
• Dizziness

Serious or Rare Side Effects

• Severe hepatotoxicity, especially with overdose
• Stevens‑Johnson syndrome
• Anaphylactic reaction
• Blood dyscrasias such as agranulocytosis
• Hypotension related to rapid intravenous administration

Paracetamol should be used with attention to patient history and clinical setting.

• Assess liver function: Check baseline hepatic enzymes in patients with liver disease.
• Monitor renal function: Adjust use in patients with severe renal impairment.
• Avoid alcohol: Advise patients to limit alcohol intake while receiving therapy.
• Use caution in pregnancy: Limit to the lowest effective dose and duration.
• Observe for allergic reactions: Discontinue if rash or anaphylaxis occurs.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Paracetamol can interact with several medicines, requiring clinical awareness.

Major Interactions (Avoid)

• Warfarin: Increased risk of bleeding due to enhanced anticoagulant effect.
• Highly hepatotoxic drugs: Combined use may exacerbate liver injury.

Moderate Interactions (Monitor Closely)

• Isoniazid: May increase risk of liver toxicity.
• Antiepileptic drugs (e.g., carbamazepine, phenytoin): May alter paracetamol metabolism.
• Certain HIV‑reversal
