Hi Vignesh This is Dr Abhishek Miryala, consultant neurologist I understand you are a diagnosed case of duchenne muscular dystrophy and you also have cardiomyopathy Unfortunately tapering of the steroid is not advisable even in the background of osteoporosis. You are anyhow on a very low dose. It is best to continue the steroid because it helps in managing duchenne muscular dystrophy and the related cardiomyopathy Don't vilify the steroid because you will only benefit from its use If can visit an endocrinologist for the treatment of osteoporosis
