Lemsip (Paracetamol)

Lemsip (paracetamol) works within the analgesic and antipyretic pathway to relieve discomfort and reduce elevated temperature.

• Pain: provides relief from mild to moderate aches such as headache, muscular or dental pain.
• Fever: lowers body temperature in febrile conditions associated with infections or inflammation.
• Cold symptoms: eases discomfort caused by common cold, including sore throat and sinus pressure.

• Paracetamol exerts its effect by inhibiting prostaglandin synthesis in the central nervous system, primarily through blockade of the cyclooxygenase (COX) pathway. This reduction in prostaglandin levels diminishes the perception of pain and resets the hypothalamic temperature set‑point, resulting in analgesia and antipyresis without significant peripheral anti‑inflammatory activity.

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

Common Side Effects

• Nausea: mild stomach upset that may accompany dosing.
• Dyspepsia: occasional indigestion or heartburn.
• Rash: skin redness or mild itching.
• Dizziness: transient light‑headedness.
• Fatigue: feeling unusually tired after use.
• Elevated liver enzymes: mild, reversible changes in laboratory tests.

Serious or Rare Side Effects

• Hepatotoxicity: severe liver injury, especially with overdose or chronic high‑dose use.
• Stevens‑Johnson syndrome: rare severe skin reaction with blistering and detachment.
• Anaphylaxis: acute allergic reaction with breathing difficulty and swelling.
• Blood dyscrasias: rare cases of thrombocytopenia or agranulocytosis.

Before using Lemsip, consider the following safety measures.

• Do not exceed recommended dose: follow prescriber or label instructions to avoid toxicity.
• Avoid alcohol: concurrent intake may increase liver strain.
• Monitor liver disease: patients with hepatic impairment should use only under medical advice.
• Use cautiously in children: dosage must be age‑appropriate and supervised.
• Store at ambient temperature: keep in the original pack, protect from moisture.

Paracetamol may interact with several medicines; awareness helps prevent complications.

Major Interactions (Avoid)

• Alcohol: combined use heightens risk of liver damage.
• Other paracetamol‑containing products: can lead to accidental overdose.
• Warfarin: may potentiate anticoagulant effect, increasing bleeding risk.

Moderate Interactions (Monitor Closely)

• Carbamazepine: may increase metabolism, reducing analgesic effect.
• Phenobarbital: can enhance hepatic clearance, lowering efficacy.
• Isoniazid: may augment hepatotoxic potential, requiring liver function monitoring.
