Abstract:
Clozapine is known to cause innocuous as well as severe and or fatal cardiovascular side effects. These side effects are commonly reported at the initiation of clozapine therapy. We report a patient who was stable on clozapine for several years but in whom we had to withhold clozapine for medical reasons and subsequently developed significant hypotension and heart rate changes when rechallenged with a small dose of clozapine.
