This medicine could lower your blood pressure too much. The risk is greater if you are sweating, dehydrated, salt-depleted, or taking other blood pressure medications or diuretics. Tell the doctor if you experience symptoms of low blood pressure, such as lightheadedness and dizziness, particularly in the first weeks of treatment.

Do not use benazepril with:

• Aliskiren

• Entresto (sacubitril/valsartan)
