This non-drowsy cough syrup contains the active ingredient guaifenesin, which belongs to a group of medicines called expectorants. Covonia works by loosening the uncomfortable phlegm that can build up in the back of your throat and in your chest. By clearing your airways, Covonia banishes that chesty cough and lets you breathe comfortably again.
Covonia is suitable for vegetarians, vegans and coeliacs. It is also free from alcohol and sugar, making it ideal for drivers or those who follow a calorie-controlled diet.
