    ### Instruction:
    What are the treatments for Postural Tachycardia Syndrome ?
    ### Response:
    Therapies for POTS are targeted at relieving low blood volume or regulating circulatory problems that could be causing the disorder. No single treatment has been found to be effect for all. A number of drugs seem to be effective in the short term. Whether they help in long term is uncertain.
