My adult daughter has had a cold for over a week now and I told her to go to a clinic and get a steroid shot to dry up the cold.  I have been given this in the past when I had a cold that just wouldnt end and it really worked.  Why wouldnt the doctor give her a shot.
Hello Steroids are meant only for emergency cases not for ordinary cases like cough. Since this is common and main reason is allergy. Allergy produce bronchoconstriction and this develop cough. So when such patient visit I prescribe my patient to take montelukast+albuterol (10 mg in each salt) , one tablet / day and patient respond at once. If cough is severe then also use chlorampheniramine + AEROSOL + menthol cough syrup. So don't use steroid, rather avoid it. This is a prescription Chat Doctor. Hot coffee and steam inhalation is also very good.
