You need to request the pharmacist to provide you with the PDR
handout for every medication, and not refer to them as the blue,orange,yellow inhaler. Do not be satisfied with the drugstore handout.
You might consider an over-the-counter cough suppressant.
You should see a physician as soon as possible for advice. Some walk-in clinics are very good. Others worthless. If your own physician can see you in a day or two, go there.
