Autonomic hyperreflexia
Treatment
This condition is life-threatening, so it is important to quickly identify and treat the problem. Proper treatment depends on the cause. If medications or drugs are causing the symptoms, those drugs must be stopped. Any underlying illness that is causing the symptoms needs to be treated. If a slowing of the heart rate is causing the symptoms, drugs called anticholinergics (such as atropine) may be used.
Very high blood pressure needs to be treated quickly but carefully because a sudden and severe drop in blood pressure is possible, and can also cause problems. Commonly used emergency drugs for high blood pressure include: nifedipine (Procardia), nitroglycerin, phenoxybenzamine hydrochloride (Dibenzyline), mecamylamine (Inversine), and diazoxide (Hyperstat). A pacemaker may be required for certain unstable heart-related situations.
Prognosis (Expectations)
The outlook depends on the underlying cause. People with autonomic hyperreflexia due to medications usually recover when the medications that are causing the symptoms are stopped. When the condition is caused by other factors, recovery depends on the success of treating the underlying disease.
Complications
Complications may occur as a result of side effects of medications. If the pulse rate drops severely, it can cause cardiac arrest. Prolonged, severe high blood pressure may cause seizures, bleeding in the eyes, stroke, or death.
Calling Your Health Care Provider
Call your health care provider if you have symptoms of autonomic hyperreflexia.
