Question: What are the treatments for Multiple System Atrophy with Orthostatic Hypotension ?
Answer: There is no cure for multiple system atrophy with orthostatic hypotension. Treatment is aimed at controlling symptoms. Anti-Parkinson medication such as Sinemet may improve the general sense of well-being. Medications to elevate blood pressure while standing are often used, but may cause high blood pressure when lying down. Individuals should sleep with the head of the bed elevated. An artificial feeding tube or breathing tube may be required for problems with swallowing and breathing.
