Intravenous nitroglycerin-induced intracranial hypertension.

Nitroglycerin therapy can cause dose-related increases in intracranial pressure. Rare cases of neurologic sequelae attributed to nitroglycerin have appeared in the literature. We report such a case, in which symptoms completely resolved after cessation of nitroglycerin therapy. Widespread use of high-dose iv nitroglycerin makes knowledge of this effect important for all practitioners.
