Paracetamol Zentiva K.S. (Paracetamol)

Paracetamol Zentiva K.S. acts on the prostaglandin pathway to provide symptomatic relief in several common conditions.

• Headache: Reduces pain intensity and improves daily functioning.
• Fever: Lowers elevated body temperature to normal range.
• Musculoskeletal pain: Alleviates aches associated with muscles and joints.
• Dental pain: Diminishes discomfort following dental procedures.
• Common cold symptoms: Helps control fever and headache associated with viral upper respiratory infections.

• Paracetamol exerts its effect primarily by inhibiting the cyclooxygenase (COX) enzymes in the central nervous system, especially COX‑2, which reduces the synthesis of prostaglandins involved in pain signaling and thermoregulation. It also modulates serotonergic pathways that contribute to its antipyretic action.

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

Common Side Effects

• Nausea: Mild stomach upset that may resolve without treatment.
• Rash: Skin redness or mild itching.
• Elevated liver enzymes: Laboratory finding without clinical symptoms.
• Headache: Paradoxical worsening of head pain in some individuals.

• Stevens‑Stevenson reaction: Severe skin blistering and detachment.
• Anaphylaxis: Rapid onset of breathing difficulty, swelling, and hypotension.
• Hepatotoxicity: Liver injury that may present with jaundice, fatigue, or abdominal pain.

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

Major Interactions (Avoid)

• Warfarin: Increased risk of bleeding due to enhanced anticoagulant effect.
• Isoniazid: Heightened potential for liver toxicity.

Moderate Interactions (Monitor Closely)

• Antiepileptic drugs (e.g., carbamazepine, phenytoin): May reduce paracetamol plasma levels.
• Alcohol: Potentiates hepatotoxic risk, especially with high‑dose regimens.
