Paracetamol Aspar Pharmaceuticals (Paracetamol)

Paracetamol acts on the central nervous system to alleviate pain and lower body temperature.

• Pain: Provides relief from mild to moderate pain such as headache, muscle aches, and dental discomfort.
• Fever: Reduces elevated body temperature associated with infections or inflammatory conditions.
• Headache: Alleviates tension‑type and migraine‑related head pain.
• Musculoskeletal pain: Helps manage aches from strains, sprains, and arthritis.
• Toothache: Eases dental pain after procedures or infection.
• Menstrual cramps: Relieves dysmenorrhea‑related discomfort.

• Paracetamol inhibits cyclooxygenase enzymes, primarily COX‑2, within the central nervous system, leading to decreased synthesis of prostaglandins that mediate pain and fever. This action reduces the perception of pain signals and resets the hypothalamic temperature set‑point, producing antipyretic effects without significant peripheral anti‑inflammatory activity.

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

Common Side Effects

• Nausea: Mild stomach upset or queasiness.
• Rash: Skin redness or mild itching.
• Elevated liver enzymes: Transient increase in hepatic markers.
• Headache: Occasional mild headache.
• Dizziness: Light‑headed sensation in some individuals.

Serious or Rare Side Effects

• Hepatotoxicity: Severe liver injury, especially with overdose.
• Stevens‑Johnson syndrome: Rare severe skin reaction.
• Anaphylaxis: Immediate hypersensitivity with breathing difficulty.
• Blood disorders: Rare cases of thrombocytopenia or neutropenia.
• Renal impairment: Uncommon kidney function decline.

Paracetamol should be used with attention to safety considerations.

• Dosage limit: Do not exceed the maximum daily dose recommended by the prescriber.
• Alcohol use: Avoid excessive alcohol, which can increase liver toxicity risk.
• Liver disease: Use caution in patients with existing hepatic impairment.
• Drug interactions: Review concomitant medications for potential interactions.
• Pediatric use: Follow age‑appropriate dosing guidelines; do not give to infants without medical advice.
• Store at ambient temperature: Keep in the original container, protect from moisture and direct heat.

Paracetamol can interact with several medicines, requiring monitoring.

Major Interactions (Avoid)

• Warfarin: May enhance anticoagulant effect and increase bleeding risk.
• Carbamazepine: Can reduce paracetamol effectiveness by increasing metabolism.

Moderate Interactions (Monitor Closely)

• Alcohol: Combined use raises potential for liver injury.
• Isoniazid: May increase risk of hepatotoxicity.
• Phenytoin: May alter hepatic metabolism of paracetamol.
• Rifampicin: Can decrease plasma concentrations of paracetamol.
