Paracetamol-Ratiopharm (Paracetamol)

Paracetamol‑Ratiopharm is an analgesic and antipyretic that acts on the body's pain‑and‑fever pathways.

• Headache: provides relief from tension‑type and mild migraine pain.
• Fever: lowers elevated body temperature associated with infections or inflammatory conditions.
• Musculoskeletal pain: eases discomfort from strains, sprains and minor joint aches.
• Dental pain: reduces pain following dental procedures or toothache.
• Common cold symptoms: helps control headache, sore throat and fever associated with viral upper‑respiratory infections.

• Paracetamol exerts its effect primarily by inhibiting cyclooxygenase enzymes in the central nervous system, which reduces the synthesis of prostaglandins involved in pain signalling and temperature regulation. It also modulates serotonergic pathways that contribute to its antipyretic action, while having minimal peripheral anti‑inflammatory activity.

Paracetamol may cause a range of adverse reactions, most of which are dose‑dependent and reversible.

Common Side Effects

• Nausea: mild stomach upset that resolves after continued use.
• Skin rash: transient erythema or itching without systemic involvement.
• Elevated liver enzymes: mild, reversible changes detected in routine blood tests.
• Headache: occasional worsening of pre‑existing headache.
• Dizziness: brief sensations of light‑headedness, especially on standing.

Serious or Rare Side Effects

• Stevens‑Johnson syndrome: severe skin blistering and mucosal involvement.
• Toxic hepatitis: significant liver injury presenting with jaundice and abdominal pain.
• Anaphylaxis: rapid onset of airway swelling, hypotension and urticaria.
• Blood dyscrasias: agranulocytosis or aplastic anaemia.
• Renal impairment: acute kidney injury in susceptible individuals.

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

• Liver disease: avoid or limit use in patients with hepatic impairment.
• Alcohol use: limit intake as chronic alcohol may increase hepatotoxic risk.
• Concomitant paracetamol‑containing products: ensure total daily dose does not exceed recommended maximum.
• Pregnancy: use only under medical supervision, especially in the third trimester.
• Age: adjust dosing for children and the elderly as directed by a healthcare professional.
• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Paracetamol can interact with several medicines, altering its efficacy or safety.

Major Interactions (Avoid)

• Warfarin: increased anticoagulant effect may raise bleeding risk.
• Isoniazid: combined use can heighten risk of liver toxicity.
• Rifampicin: may reduce paracetamol plasma concentrations.

Moderate Interactions (Monitor Closely)

• Antiepileptics (e.g., carbamazepine, phenytoin): may increase hepatic metabolism of paracetamol.
• HIV protease inhibitors: potential for altered liver enzyme activity.
• Oral contraceptives: may slightly raise paracetamol plasma levels.
