After taking this I am becoming very fatty, especially may face & stomach. Earlier my weight and height was 49-153 cm. Is there any side effects to take this medicine and kindly let me know how to reduce my weight.

### output:

I read your question carefully. I do understand your concern. Betamesathon is a corticosteroid. Like all corticosteroids, dexamethasone affects your metabolism and how your body deposits fats. As a consequence, your appetite might increase leading to weight gain, especially to extra deposits of fat in your abdomen. Ito minimize this effect, watch your calories and exercise regularly. In general, your stomach will return to its normal size, 8-12 months after you discontinue steroids. Besides this, you should maintain adequate vitamin D and Calcium intake through diet and supplement. You also should have a check-up regarding osteoporosis risk assessment. The answer above was for the side effects of steroids in general and I'm not saying to stop the steroids (actually, stopping abruptly or tapering off to quickly you might experience with Chat Doctor.  Regarding Memphis vulgarism infection, the first line treatment are corticosteroids. You should consult with your doctor about second-line therapies (azathioprine, rituximab, Dawson etc.). You should also be careful regarding contact sports or any other activity that traumatize the skin. I hope you do well and wish you a good health.
