Benadryl Cough Formula Syrup

Dextromethorphan Hydrobromide, Diphenhydramine Hydrochloride, Ammonium Chloride, Sodium Citrate (strengths vary by pack; check label)

Symptomatic relief of dry/irritating cough due to common cold or throat irritation, cough with allergy/post-nasal drip, relief from associated runny nose and sneezing

Dextromethorphan suppresses the cough reflex by acting on the cough center in the brain. Diphenhydramine is an antihistamine that reduces allergy symptoms like runny nose and sneezing and also has mild cough-suppressant action. Ammonium chloride and sodium citrate help loosen and thin mucus and soothe throat irritation.

Shake well before use. Take the measured dose using a cup/spoon as advised on the label or by a doctor. Usually taken 2–3 times daily; may be taken with or without food. Do not exceed recommended dose; avoid use with other cough/cold products containing similar ingredients.

Drowsiness, dizziness, dry mouth, nausea, vomiting, constipation, blurred vision, headache

Not recommended for children without medical advice. Do not use if taking MAO inhibitors (or within 14 days of stopping) due to risk of serious reactions. Seek medical advice if cough persists >7 days, is recurrent, or is accompanied by fever, rash, persistent headache, breathing difficulty, or thick/colored sputum.
