Buy Covonia Night Time Formula

Covonia Night Time Formula is designed to relieve dry coughs and congestion from colds during the night.


How Covonia Night Time Formula works

Covonia Night Time Formula contains the active ingredient dextromethorphan hydrobromide. Dextromethorphan hydrobromide reduces the urge to cough. It is particularly effective for those who have a dry cough. 

The formula also contains diphenhydramine hydrochloride which is an antihistamine. Diphenhydramine hydrochloride helps to dry up a runny nose and relieve nasal congestion.



Always take Covonia Night Time Formula exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

Take 3 x 5ml spoonfuls of the formula at bedtime. You can repeat the dosage after 6 hours if required.
