So - you've had a persistent cough for a good long while. You know that you have some heinous allergies. So, you go to the doctor - like you were always told you are SUPPOSED to do...

The doctor prescribes a "medicine" to help get rid of the cough (your original symptom). You spend the next week (plus) taking the meds - and the cough still persists.

Finally, you decide "enough is enough" and you go back to the doctor. The doctor then switches your meds... WHY??? Because the one he ORIGINALLY prescribed has "a side effect of producing coughing"...

I'm no rocket scientist (nor did I sleep at a Holiday Inn Express last night) - but, Doc, it seems to me you shouldn't prescribe a medication that can INDUCE COUGHING to someone whose only major symptom is a PERSISTENT COUGH!!!
