Your doctor might often check your blood pressure and your kidney function.

Get a doctor’s help if you are suffering from vomiting or diarrhea or sweating more than usual. You can quickly become dehydrated while taking this medicine. It can lead to reduced blood pressure, electrolyte disorders, or kidney failure while taking Benazepril.

Benazepril dosage

It might not be possible to mention all dosages and drug forms here. Your dosage, drug form, and dosage intensity may vary depending upon:

  • Your age
  • The condition to treat
  • The severity of your condition
  • Other medical conditions you have
  • How you react to the first dose

Dosage for high blood pressure

Adult dosage (ages 18 to 64 years)

  1. The typical dosage is 10 mg tablet by mouth once daily.
  2. The maintenance dosage is 20 to 40 mg once daily or in two equally divided doses.

Child dosage (ages 6 to 17 years)

  1. The typical dosage is 0.2 mg/kg once daily.
  2. It’s important to note that children in this age group shouldn’t consume this drug if their creatinine clearance (CrCl) is less than 30 mL/min/1.73 m2.

Child dosage (ages 0 to 5 years)

Doctors do not recommend this medication for children younger than six years of age.

Senior dosage (ages 65 years and above)

Old age people suffer from kidney problems. It can lead to the body processing drugs more slowly. As a result, a higher amount of drugs stays in the body for a longer time, increasing the risk of side effects even more.

Your doctor may begin with a low dosage or a different dosing schedule to help prevent levels of this drug from building up too much in your body.


It’s uncommon to see human overdoses of Benazepril. Still, the most common manifestation of its overdosage in humans is likely to be hypotension. Hypotension is associated with electrolyte disturbances and renal failure.

While using Benazepril, consider dialysis to support patients with severely impaired renal function.

If ingestion is recent, consider activated charcoal. Consider gastric decontamination (e.g., vomiting, gastric lavage) in the early period after ingestion.

You should monitor blood pressure regularly. In the case of marked hypotension, consider using vasopressors.

It would be best if you immediately get emergency medical attention or call the Poison Help line at 1-800-222-1222 in case of overdose symptoms.

What to avoid while using Benazepril?

You should avoid getting up too fast from a sitting or lying position, or you may feel dizzy.

Also, avoid becoming overheated or dehydrated during exercise, in hot weather, or by not drinking enough fluids. Benazepril can decrease sweating, and you may be more prone to heatstroke.

Refrain from drinking alcohol because it can lower your blood pressure and increase Benazepril’s specific side effects.

Unless your doctor advises, do not use potassium supplements or salt substitutes along with Benazepril.
