Lemsip Max Cold & Flu Blackcurrant (Phenylephrine Hydrochloride, Paracetamol)

• Phenylephrine Hydrochloride and paracetamol act on the respiratory and pain pathways to relieve common cold and flu symptoms.
• Nasal congestion: reduces swelling of nasal mucosa, improving airflow.
• Headache: alleviates pain associated with sinus pressure and fever.
• Fever and sore throat: lowers body temperature and eases throat discomfort.

• Phenylephrine hydrochloride is an alpha‑1 adrenergic receptor agonist that causes vasoconstriction of the nasal mucosal blood vessels, decreasing edema and nasal obstruction. Paracetamol exerts central analgesic and antipyretic effects by inhibiting cyclooxygenase enzymes in the brain, reducing prostaglandin synthesis and thereby lowering pain perception and body temperature. The combined action provides rapid symptomatic relief without significant anti‑inflammatory activity.

Phenylephrine Hydrochloride and paracetamol may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Nausea: mild stomach upset.
