Your blood pressure will need to be checked often, and you may need frequent blood tests.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking this medicine. This can lead to very low blood pressure, electrolyte disorders, or kidney failure while you are taking benazepril.
If you need surgery, tell the surgeon ahead of time that you are using benazepril.
