Sir my mother aged about 70 years, is under medication for copd from 2003. From last one year, she is on oxygen (around 2 liters/minute) and intermittent bipap support. Now, though we are maintaining her spo2 around 85-90, she is still feeling difficulty in breathing. Cough or sputum symptoms are not observed. But she is feeling comfortable, if we are giving medrol tablets (methyl prednisolone) 8 m.g at least for 3 to 5 days in addition to regular inhalers foracort and tiomate. Now my query is (i) can medrol be given daily? What's the safe dose (like 4 mg or 8 mg, which can be given daily? If not (ii) with how many days gap, again the medicine medrol can given? Pls do the needful. Thanks in advance.
