Can I take Supremin antitussive syrup tomorrow instead of Dexacaps?

Supremin has indications for use in acute, dry cough and in such cases it can be used if there are no contraindications listed in the leaflet. The composition of Supremin is different from that of Dexacaps. I do not know the details of your case, so it is difficult for me to advise a specific preparation - antitussive drugs can be used for a short time as part of self-medication, but with a longer lasting cough, a medical consultation is indicated. When choosing an over-the-counter drug and without consulting a doctor, possible interactions should be taken into account. If the doctor chooses medicines, you need to inform him about all preparations taken permanently.
