Paracetamol Zentiva Lab (Paracetamol)

Paracetamol Zentiva Lab is an analgesic and antipyretic that acts on common pain‑related pathways and fever mechanisms.

• Headache: provides relief from tension‑type and mild migraine headaches.
• Fever: reduces elevated body temperature associated with infections.
• Musculoskeletal pain: eases mild to moderate pain from strains, sprains and backache.
• Dental pain: alleviates discomfort following dental procedures.
• Osteoarthritis: helps manage mild pain associated with joint degeneration.

• Paracetamol exerts its effect primarily by inhibiting cyclo‑cyclooxygenase (COX) enzymes in the central nervous system, which reduces prostaglandin synthesis. This action lowers the hypothalamic set‑point for temperature regulation and diminishes pain signal transmission, providing antipyretic and analgesic effects without significant peripheral anti‑inflammatory activity.

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

Common Side Effects

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

Serious or Rare Side Effects

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

When using Paracetamol Zentiva Lab, consider the following safety measures:

• Liver function monitoring: assess baseline liver enzymes in patients with chronic liver disease.
• Alcohol consumption: limit intake as alcohol can increase hepatotoxic risk.
• Concomitant medications: review other products containing paracetamol to avoid excess dosing.
• Pregnancy and lactation: use only if clearly indicated and prescribed.
• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Paracetamol may interact with several medicines, requiring attention to dosage and monitoring.

Major Interactions (Avoid)

• Warfarin: may enhance anticoagulant effect, increasing bleeding risk.
• Isoniazid: combined use can raise risk of liver toxicity.

Moderate Interact ions (Monitor Closely)

• Antiepileptic drugs (e.g., carbamazepine, phenytoin): may reduce paracetamol plasma levels.
• Rifampicin: may increase metabolism of paracetamol, lowering its effectiveness.
• Oral contraceptives: may slightly increase hepatotoxic potential.
