CP Pharma Diphenhydramine Expectorant 120ml

CP Pharma Diphenhydramine Expectorant is a combination cough syrup, bringing together diphenhydramine, ammonium chloride, sodium citrate, and menthol to relieve coughing and throat irritation associated with colds and respiratory tract infections. If you're using this for the first time, you're probably wondering how the ingredients work together — diphenhydramine acts as an antihistamine and antitussive to calm coughing and reduce congestion, while ammonium chloride and sodium citrate work as expectorants to help loosen and clear mucus, with menthol providing a soothing, cooling sensation. Because diphenhydramine is a first-generation antihistamine, drowsiness is a common effect, which is why this syrup is often more suited to evening or nighttime use. It's meant for short-term symptomatic relief, so if your cough persists beyond a week or is accompanied by fever or worsening symptoms, it's worth checking in with your doctor. As with any sedating cough medicine, it's worth being cautious about driving or operating machinery after taking it, and checking with your doctor or pharmacist first if you have asthma, glaucoma, prostate issues, or are pregnant or breastfeeding.

For adults and children over 12 years, the typical dose is 5 to 10ml every 4 to 6 hours; for children 6 to 12 years, 2.5 to 5ml every 4 to 6 hours; and for children 2 to 5 years, 2.5ml every 4 to 6 hours. Do not exceed the maximum daily amount stated on the packaging, and consult a doctor before giving this to children under 2 years.

CP Pharma Diphenhydramine Expectorant generally has a shelf life of around 2–3 years from the date of manufacture when stored correctly and unopened. Always check the expiry date printed on the bottle before use, and note that once opened, the bottle is generally best used within about 30 days.

• Diphenhydramine Hydrochloride – a first-generation antihistamine with antitussive and anticholinergic properties.
• Ammonium Chloride – an expectorant that helps thin and loosen mucus.
• Sodium Citrate – a mucolytic agent that helps break down mucus.
• Menthol – provides a soothing, cooling sensation in the throat.

• Known hypersensitivity to diphenhydramine, ammonium chloride, or any other ingredient in the formulation
• Asthma or a persistent, productive cough, given the drying effect on respiratory secretions
• Narrow-angle glaucoma
• Benign prostatic hyperplasia or difficulty urinating
• Moderate to severe liver or kidney impairment
• Use with, or within 2 weeks of stopping, monoamine oxidase inhibitors (MAOIs)

This medication can cause additive sedation when combined with alcohol, sleeping tablets, anti-anxiety medications, or other sedating drugs, so these combinations are best avoided. It also interacts with monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants, which can increase diphenhydramine-related side effects, so it's important to inform your doctor or pharmacist about all medications you're taking before starting this syrup.
