I have been on Benazepril 10mg tab for two years and have not had any problems and my blood pressure has lowered and stayed near perfect. I purchased the pills from Kroger. Last month because Kroger raised their prices, I had my prescription through Sams Club. I have not felt good all month and my blood pressure is higher than it was two years ago. The pills look differently but the pharmacist at Sams said it is the same medicine. Are there several companies who make Benazepril? My email is YYYY@YYYY
