Lemsip Dry Cough (Glycerol)

• Lemsip Dry Cough, containing glycerol, acts as a demulcent to soothe the upper respiratory tract and reduce irritation that leads to a dry cough.
• Dry cough: provides a moisturizing coating that eases throat irritation and reduces cough frequency.
• Throat irritation: helps alleviate discomfort caused by dryness or environmental irritants.
• Upper respiratory tract irritation: supports mucosal comfort during mild colds or allergic responses.

• Glycerol exerts its effect primarily through its hygroscopic properties. When administered orally, it attracts and retains water in the mucous membranes of the oropharynx, forming a viscous, protective film. This film reduces mechanical stimulation of sensory nerves that trigger the cough reflex, thereby diminishing the urge to cough without acting on the central nervous system and does not interfere with normal swallowing.

Glycerol may be associated with a range of adverse reactions, most of which are mild and reversible.

Common Side Effects

• Mild nausea: occasional feeling of stomach unease after ingestion.
• Transient mouth dryness: brief sensation of dryness in the oral cavity.
• Mild abdominal discomfort: slight cramping or bloating.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Severe abdominal pain: intense pain requiring medical attention.
• Anaphylaxis: rare life‑threatening systemic hypersensitivity.

• When using Lemsip Dry Cough, certain precautions should be observed to ensure safe use.
• Allergy check: avoid if you have known hypersensitivity to glycerol or any excipients.
• Age limitation: consult a healthcare professional before giving to children under two years.
• Medical conditions: inform your doctor if you have chronic gastrointestinal disorders.
• Concurrent medications: discuss with a pharmacist any other demulcent or laxative products.
• Pregnancy and lactation: seek medical advice before use during pregnancy or breastfeeding.
• Store at ambient temperature: keep the product in its original container, protected from moisture and direct heat.

Glycerol has a low potential for drug‑drug interactions, but certain combinations may require attention.

Major Interactions (Avoid)

• None identified: no major pharmacokinetic or pharmacodynamic interactions have been documented.
• Concurrent use of high‑dose osmotic agents: may increase risk of dehydration.

Moderate Interactions (Monitor Closely)

• Other demulcents or mucolytics: combined use may enhance gastrointestinal side effects.
• Laxatives containing glycerin: additive osmotic effect could lead to diarrhea.
• Anticholinergic medications: may reduce saliva production, potentially diminishing glycerol’s soothing effect.
