Hi ! Good afternoon. I am Dr Shareef answering your query. Betnesol as you already know can be a cause of increase in weight which is obvious in your case. Apart from this, in prolonged use of steroids such as betnesol, there could be some rounded appearance of the face, electrolyte disturbances, and hyper acidity to elaborate a few. However, the side effects are weighed against the benefits, and if required medically, these drugs have to be prescribed by the treating doctor. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
