Max Strength All In One Hot Lemon Menthol Flavour (Phenylephrine Hydrochloride, Guaifenesin, Paracetamol)

The combination of phenylephrine, guaifenesin and paracetamol acts on multiple pathways to alleviate common cold and flu symptoms.

• Nasal congestion: reduces swelling of nasal mucosa and improves airflow.
• Cough: thins respiratory secretions to aid expectoration.
• Headache: alleviates pain associated with viral infections.
• Fever: lowers elevated body temperature.

• Phenylephrine hydrochloride stimulates alpha‑adrenergic receptors causing vasoconstriction of nasal mucosal vessels, which decreases swelling and congestion. Guaifenesin raises the volume and reduces the viscosity of airway secretions, promoting mucociliary clearance. Paracetamol inhibits central cyclooxygenase activity, reducing prostaglandin synthesis and providing analgesic and antipyretic effects.

Adverse reactions may occur with any medication and should be monitored.
