Sorry to hear about your problem.
As per manufacturer's description, the effective half life of this drug, Benazapril, is 10-11 hours after multiple doses have been taken.
At most this takes 24-48 hours to get out of your body completely.
I was wondering if your doctor has switched you to another blood pressure medication or not.
This is because if you are not given any antihypertensive medication, there is a possibility to develo rebound hypertension (in which your blood pressure goes very high), which can be a serious condition.
So if not already, you should monitor your blood pressure and must be on any other blood pressure medication to keep it under control.
You can go to ER and have your blood pressure checked and can get a prescription as well.
I hope this clarifies and answers your question. Kindest Regards XXXXX XXXXX luck.
