Abstract
Midodrine was the first medication approved by the Food and Drug Administration (FDA) for the treatment of orthostatic hypotension. Pharmacologically, midodrine is a peripheral selective alpha-1-adrenergic agonist that can improve standing, sitting, and supine systolic blood pressure. Common side effects include bradycardia, supine hypertension, and paresthesia. A novel side effect of midodrine-induced nightmares has been reported in our patient. To our knowledge, this is the first reported case of midodrine-induced nightmares. To investigate and report a clinically significant and unique drug adverse event of midodrine in the treatment of orthostatic hypotension. This report describes a case of persistent nightmares associated with midodrine use in an 83-year-old male who experienced frequent syncope episodes treated with midodrine for orthostatic hypotension (OH). After the initiation of midodrine, the patient complained of increased nightmares, which quickly led to his refusal of the medication, despite the initial improvements in his blood pressure. The timing of administration included an evening dose at 21:00. This novel adverse event of midodrine-induced nightmares will be highlighted and explored in this case report. This case demonstrated a unique adverse event of nightmares caused by midodrine. It is hypothesized that autonomic dysfunction plays a role and further investigations should be conducted to confirm this theory. We hope that our case report highlights the importance of careful consideration when prescribing midodrine in older people with orthostatic hypotension.
