Nocegap (Paracetamol)

Paracetamol is used for the relief of mild to moderate pain and reduction of fever across various conditions.

• Headache: alleviates tension‑type and mild migraine pain.
• Fever: lowers elevated body temperature associated with infections or inflammation.
• Musculoskeletal pain: reduces discomfort from strains, sprains and minor injuries.

• Paracetamol acts centrally by inhibiting cyclooxygenase enzymes, primarily COX‑2, which reduces the synthesis of prostaglandins in the brain and spinal cord. This decrease in prostaglandin levels diminishes the perception of pain and lowers the hypothalamic set‑point for temperature regulation, providing analgesic and antipyretic effects.

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

Common Side Effects

• Nausea: mild stomach upset after ingestion.
• Skin rash: transient erythema or itching.
• Elevated liver enzymes: mild, often reversible changes.
• Headache: occasional rebound headache.
• Dizziness: brief sensation of light‑headedness.
• Gastrointestinal discomfort: mild abdominal pain.

Serious or Rare Side Effects

• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Acute liver failure: especially with overdose or chronic high‑dose use.
• Blood disorders: agranulocytosis or thrombocytopenia.
• Anaphylaxis: rare but potentially life‑threatening allergic response.
• Renal impairment: acute kidney injury in susceptible individuals.
• Hypersensitivity: swelling of face, lips or tongue.

Paracetamol should be used with awareness of specific safety considerations.

• Dosage adjustment: reduce dose in patients with hepatic impairment.
• Alcohol avoidance: limit alcohol intake to reduce risk of liver injury.
• Concomitant hepatotoxic drugs: monitor when used with other liver‑affecting medicines.
• Pregnancy: discuss use with a healthcare professional before taking.
• Breastfeeding: consult a physician to assess safety for the infant.
• Store at ambient temperature: keep below 25 °C in the original packaging, protect from moisture and direct sunlight.

Paracetamol can interact with several medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Alcohol: combined use increases risk of hepatotoxicity.
• Other hepatotoxic agents (e.g., isoniazid, methotrexate): may exacerbate liver damage.
• Warfarin: paracetamol can potentiate anticoagulant effect, raising bleeding risk.

Moderate Interactions (Monitor Closely)

• Carbamazepine: may increase paracetamol metabolism, reducing efficacy.
• Phenobarbital: induces hepatic enzymes that accelerate paracetamol clearance.
• Phenytoin: similar enzyme‑inducing effect that may lower drug levels.
