Dear Kpatrick,
Orthostatic hypotension is another name for neurocardiogenic near-syncope, which means that the autonomic nervous system, the part of the nervous system that controls the heart rate and blood pressure, is more active than normal. This is something that we see in adolescents frequently. The most common reason for this is relative dehydration, which we also see frequently in adolescents. That said, in not being able to evaluate you daughter, I can’t say that this is the cause for sure. Hopefully the emergency department told you how to fix this. She needs to make sure that her tank of fluid is full, having four 8-12 ounce glasses of fluid and a salty snack daily. She should not skip meals, and she should eliminate caffeine, as it is a diuretic (it makes her urinate the fluid back out). If she continues to have symptoms despite these interventions, she may need some medications to help support her blood pressure. Medications that we use for this include fludrocortisone and midodrine; you can discuss these further with your primary care provider if the initial interventions listed above don’t work. Finally, if this progresses in severity, it could also be dysautonomia, which is a severe malfunction of the autonomic nervous system. Overall, although Adderall (adderrall) increases the blood pressure and heart rate slightly, it has not been demonstrated to cause near-syncope. In the end, I definitely would not pass this off. Work with your primary care provider in a stepwise fashion so that she has escalating interventions that will hopefully help her.
