<s>[INST] ok, I have asthma and sinustitus, I went to the doctor because I was not feeling very well and my specialist gave me 7 tablets of prednisone 50 mg for 7 days , I have three more doses to go. I am getting better slowly. I was wondering why I need to take this drug, periodically when I get sick like this. Thank you. [/INST] Hello, Welcome to Chat Doctor, As you are a known case of asthma for which your doctor has prescribed prednisolone 50 mg for 7 days, you are also known to have infection of sinus. Your doctor has prescribed the oral steroids for your symptoms of asthma, because it will reduce the edema caused by the allergens, and it helps to dilate the bronchioles which helps to relieve the symptoms of bronchospasm. As your doctor has prescribed this medicine you have to take it for 7 days, and you cannot discontinue abruptly. For sinus infection you may require the course of antibiotics, so I would suggest you to lateral Antibiotics like Tab Autoclave, 625 mg, twice daily for 5 days. Oral antihistamines like Least for 5 days. Thank you. </s>
