Parakron (Paracetamol)

Paracetamol is an analgesic and antipyretic that acts on the central nervous system to relieve pain and lower temperature.

• Headache: provides relief from mild to moderate tension‑type headaches.
• Fever: reduces elevated body temperature in febrile illnesses.
• Musculoskeletal pain: eases discomfort from muscle aches, back pain and minor joint pain.
• Dental pain: alleviates pain associated with toothaches and minor dental procedures.
• Cold symptoms: helps control pain and fever that accompany common colds.

• Paracetamol exerts its effect primarily by inhibiting cyclooxygenase enzymes in the central nervous system, which reduces prostaglandin synthesis. This action lowers the pain‑sensing threshold and produces antipyretic effects by acting on hypothalamic heat‑regulation centers. The exact peripheral mechanism remains less defined compared with non‑steroidal anti‑inflammatory drugs.

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

Common Side Effects

• Nausea: mild stomach upset may be reported.
• Skin rash: occasional mild erythema or itching.
• Elevated liver enzymes: transient increases in laboratory 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.
• Blood disorders: rare cases of thrombocytopenia or neutropenia.
• Anaphylaxis: extremely rare allergic reaction requiring immediate medical attention.

Paracetamol should be used with awareness of its safety profile and patient‑specific factors.

• Dose limits: adhere to recommended maximum daily intake to avoid liver toxicity.
• Pre‑existing liver disease: use only under medical supervision.
• Alcohol consumption: limit intake as alcohol can increase hepatotoxic risk.
• Pregnancy and lactation: consult a healthcare professional before use.
• Concomitant medications: review other products containing paracetamol to prevent accidental overdose.
• 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: increased anticoagulant effect may raise bleeding risk.

Moderate Interactions (Monitor Closely)

• Isoniazid: combined use can enhance liver toxicity.
• Antiepileptics (e.g., carbamazepine, phenytoin): may reduce paracetamol clearance.
• Alcoholic beverages: concurrent use heightens hepatotoxic potential.
• Certain HIV protease inhibitors: may alter paracetamol metabolism.
• High‑dose vitamin C: can affect renal excretion of paracetamol metabolites.
