i was just sick with a respiratory infection/ marathon asthma for 5 weeks. if you got a prednisone dose pak and you are still sick it might help you to get a prescription for a higher dose such as 40mg for 3 days 30 mg for next three days, 20 mg next three days then 10 mg for 3 days, 12 days total. this is what i have to do . sometimes it starts as high as 60 mg depending on how sick i am. also if the z pak antibiotic doesnt knock out the infection biaxin may be called for. unfortunately i have become an expert in this area due to 10 years of chronic respiratory infections. i can feel them coming on early and if i dont get the regimen going i ll be flat on my back for weeks within 24 hours. i also have a nebulizer but unless your infections or asthma are chronic then you probably wont need that.
