Covonia Night Time Formula 150ml is a dual-action cough medicine designed to relieve dry, irritating coughs and nasal congestion at night, helping you breathe easier and sleep better.
Each dose combines two active ingredients for maximum overnight relief:
Diphenhydramine Hydrochloride (10mg) – an antihistamine that helps dry up a runny nose and relieve congestion.
Dextromethorphan Hydrobromide (6.65mg) – a cough suppressant that reduces the urge to cough.
Together, they provide soothing comfort for those struggling with cold-related coughing or night time congestion.
