I think I have bronchitis but I can't get to a doctor until Monday?

If you have dry cough, usually cough syrup doesnt work. They are mainly for cough with phlegm. U can try taking cough tablets that goes by under the brand name of Copastin ( chemical name is Cloperastine HCl) 10 mg 3 times a day. If its severe cough at night before sleeping, instead of one tablet, take 2. As for your stuffed nose, u need to take Clarinase (Loratadine) OR Zyrtec (Cetirizine) OR Piriton ( chlorphenamin). I think clarinase shoud be sufficient. I dont knw which brand names are in your country, so thats why i gave you their chemical names also ( because that is the universal drug name). As for your sore throat, you can take lozenges like Difflam ( Benzydamine), not more than 12 lozenges a day.
