Hello, Thank you for asking at HCM. I went through your history and would like to know more about your asthma like - do you get asthma attack at times other than exercise? If yes, how frequently and how severe are they? Do you have any other allergies like nose allergies, food allergies, etc? At present, I would like to make suggestions for you as follows: 1. Regarding side effects of Aerocort, it contains two drugs - salbutamol & beclomethasone. Common side effects of salbutamol are tremors, feeling of heart beats, rapid heart beats, etc. Beclomethasone is a corticosteroid in inhaled form. Although it is safe as it directly acts in lung. Common side effects of inhaled form are throat irritation, local infection in throat, change in voice, etc. With long term use in high dose, it can cause side effects caused by other steroids - typical obesity, hypertension, diabetes, cataract, gastritis, etc. 2. In my opinion, if you are not experiencing any of the side effects described above, it can be considered safe to use the inhaler for you. 3. Were I treating you, I would suggest you allergy testing which will help you identify the substances causing symptoms to you and also to know how to avoid them. Based on allergy testing, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune system to gradually improve allergy symptoms over a long time. 4. I would also suggest you weight reduction as obesity significantly can contribute to asthma symptoms. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Thank you & Regards.
