Paracetamol Zentiva (Paracetamol)

Paracetamol Zentiva is an analgesic and antipyretic that acts on the body's pain‑relief and temperature‑regulation pathways.

• Headache: provides relief from tension‑type and migraine‑associated pain.
• Fever: reduces elevated body temperature in infectious or inflammatory conditions.
• Musculoskeletal pain: alleviates discomfort from strains, sprains and minor joint aches.
• Dental pain: eases pain following dental procedures or toothache.
• Cold symptoms: helps control pain and fever associated with common colds.

• Paracetamol exerts its effect by inhibiting cyclooxygenase enzymes in the central nervous system, which reduces the synthesis of prostagcent prostaglandins involved in pain signaling and thermoregulation. This action occurs primarily in the brain and spinal cord, providing analgesic and antipyretic effects without significant peripheral anti‑inflammatory activity.

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

Common Side Effects

• Nausea: mild stomach upset may be reported.
• Rash: occasional skin redness or itching.
• Elevated liver enzymes: transient changes detected in blood tests.

Serious or Rare Side Effects

• Hepatotoxicity: risk of liver injury with overdose or prolonged high‑dose use.
• Stevens‑Johnson syndrome: rare severe skin reaction.
• Anaphylaxis: rare allergic response requiring immediate medical attention.
• Blood disorders: uncommon cases of thrombocytopenia or neutropenia.

When using Paracetamol Zentiva, consider the following safety measures:

• Dose limitation: adhere to recommended maximum daily dose to avoid liver toxicity.
• Alcohol use: limit intake as concurrent alcohol can increase hepatic risk.
• Pre‑existing liver disease: use only under medical supervision.
• Pregnancy and lactation: consult healthcare professional before use.
• Pediatric use: ensure age‑appropriate dosing as directed by a clinician.
• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Paracetamol can interact with several medicines, requiring awareness of the interaction level.

Major Interactions (Avoid)

• Warfarin: may enhance anticoagulant effect and increase bleeding risk.
• Isoniazid: can potentiate hepatotoxic potential when combined.

Moderate Interactions (Monitor Closely)

• Antiepileptic drugs (e.g., carbamazepine, phenytoin): may increase metabolism of paracetamol, reducing efficacy.
• Rifampicin: induces hepatic enzymes that accelerate paracetamol clearance.
• Oral contraceptives: may slightly increase risk of liver enzyme elevation.
