OK, I went to a doctor about 2 weeks ago because I had a really bad sore throat, and I been had a stuffy nose for at least about a whole month now, I am 15 years old and my doctor prescribed me Amoxcicillan for my sore throat, and my sore throat is gone now but I still have a stuffy nose, and he prescribed me Q-dryl 12.5MG/5Ml Elixir, my brother that is 18 years old also went there for a cough and such, and he got C-phen DM syrup, which will relieve my stuffy nose better? The c-phen or Q-dryl?
