“Can medication fix chronic cough?”

I recommend you seek the advice of an in-person medical professional to find out the true underlying reason for your chronic cough. There are just too many possible reasons that might cause such a symptom, and someone needs to provide a thorough evaluation as soon as possible, instead of just answering this question remotely. Please see a doctor. There are certain conditions with coughing symptoms that medication will mask, but not adequately treat. For any illness, you want to treat the cause, not just the symptoms, whenever possible. "Don't judge each day by the harvest you reap but by the seeds that you plant." - Robert Louis Stevenson
