Midodrine is an oral drug used to treat orthostatic hypotension in patients who do not respond to traditional therapy. It activates alpha-adrenergic receptors, leading to peripheral vasoconstriction and an increase in vascular tone and blood pressure. This effect can cause serious supine hypertension. Patients should be monitored in the standing, sitting, and supine positions to determine whether this will be a problem. It is also important to monitor heart rate, respirations, and urine output in this patient. However, assessing for supine hypertension would pose the greatest threat to the patient and would take priority.

Visitation does not need to be limited.
