Lemsip Cough Max For Chesty Cough & Cold (Phenylephrine Hydrochloride, Guaifenesin, Paracetamol)

Lemsip Cough Max combines a decongestant, an expectorant and an analgesic to address symptoms of upper respiratory infections.

• Chesty cough: loosens mucus and facilitates expectoration, reducing cough frequency.
• Nasal congestion: constricts nasal blood vessels, decreasing swelling and improving airflow.
• Fever and headache: lowers elevated temperature and eases pain associated with colds or influenza.

• Phenylephrine hydrochloride acts as an alpha‑adrenergic agonist causing vasoconstriction of nasal mucosal vessels, which reduces congestion. Guaifenesin increases the volume and decreases the viscosity of respiratory secretions, promoting clearance of mucus. Paracetamol provides analgesic and antipyretic effects through central inhibition of cyclooxygenase enzymes, thereby reducing pain and fever.

Common side effects are generally mild and transient.

Common Side Effects

• Nausea: mild stomach upset that may resolve without intervention.
• Dizziness: temporary light‑headedness, especially when standing quickly.
• Dry mouth: reduced salivation due to the decongestant component.
• Headache: mild headache that often improves with continued use.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling of face or throat, requiring immediate medical attention.
• Severe hypertension: marked increase in blood pressure, especially in susceptible individuals.
• Liver enzyme elevation: abnormal liver function tests indicating possible hepatic stress.
• Anaphylaxis: rare but life‑threatening systemic allergic response.
• Blood disorders: rare cases of thrombocytopenia or neutropenia.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before using Lemsip Cough Max, consider the following safety measures.

• Pregnancy: consult a healthcare professional before use, as safety data are limited.
• Cardiovascular disease: use with caution in patients with hypertension or heart conditions.
• Liver impairment: monitor paracetamol intake to avoid hepatic overload.
• Drug interactions: avoid simultaneous use of other decongestants or paracetamol‑containing products.
• Store at ambient temperature: keep below 25°C, retain in the original packaging, and protect from moisture.

Lemsip Cough Max may interact with several medication classes.

Major Interactions (Avoid)

• MAO inhibitors: concurrent use can precipitate hypertensive crisis.
• Additional paracetamol products: risk of overdose and liver toxicity.
• Certain antidepressants (e.g., SSRIs): phenylephrine may increase blood pressure.

Moderate Interactions (Monitor Closely)

• Antihypertensive agents: phenylephrine may diminish their efficacy.
• Anticoagulants (e.g., warfarin): paracetamol can enhance anticoagulant effect.
• Diuretics: phenylephrine may cause fluid retention and electrolyte shifts.
