Asthma is a disease of the human respiratory system where the airways narrow, often in response to a "trigger" such as exposure to an allergen, cold air, exercise, or emotional stress. This airway narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which respond to bronchodilators.
As someone who often has allergic reactions to medications, I would consider stopping the med or at least getting a second opinion from an Allergist.
Allergic reactions tend to get worse with more exposure, so if you continue with BREO, be aware of your symptoms. I might suggest taking pics of your rashes in case you do decide to get a second opinion.
All the best <3
