If your urinalysis reports a positive test for sugar that isn’t supposed to be, don’t panic first tell the doctor that you are using a corticosteroid its due to the steroid or you may have an undiagnosed condition. How to apply a topical medication? well, you should apply a thin layer of the topical medication to your skin and rub it gently until completely dissolved. The most common side effects are blurred vision (or seeing halos around lights), palpitations, changes in mood, sleep disturbance, weight gain, facial puffiness, and feeling tired.
