What are the uses for benazepril?

What are the side effects of benazepril?

Benazepril is generally well tolerated and side effects are usually mild and transient. Side effects include:

A dry, persistent cough has been reported with the use of benazepril and other ACE inhibitors. Coughing resolves after discontinuing the medication.

In rare instances, liver dysfunction and skin yellowing (jaundice) have been reported with ACE inhibitors. Benazepril should not be taken by people with a known allergy to ACE inhibitors. Swelling of the facial tissues and even the upper airways has been reported with ACE inhibitors on very rare occasions, and can lead to serious breathing difficulties. In rare instances, low white blood cell counts have been reported with the use of one ACE inhibitor. Low white blood cells increase the patient's risk of infections.

What is the dosage for benazepril?

  • The usual starting dose of benazepril is 10 mg daily. If patients are taking a diuretic (water pill) the starting dose is 5 mg daily.
  • Doses may be increased to 20-40 mg once daily or divided and administered twice daily.

Which drugs or supplements interact with benazepril?

  • Combining benazepril with potassium supplements, potassium containing salt substitutes, and potassium conserving diuretics such as amiloride (Moduretic), spironolactone (Aldactone), and triamterene (Dyazide, Maxzide), can lead to dangerously high blood levels of potassium.
  • Combining benazepril or other ACE inhibitors with nonsteroidal anti-inflammatory drugs (NSAIDs) in patients who are elderly, fluid-depleted (including those on diuretic therapy), or with poor kidney function may result in reduced kidney function, including kidney failure. These effects usually are reversible.
  • There have been reports that aspirin and other NSAIDs such as ibuprofen (Advil, Children's Advil/Motrin, Medipren, Motrin, Nuprin, PediaCare Fever, and many others), indomethacin (Indocin, Indocin-SR), and naproxen (Anaprox, Naprelan, Naprosyn, Aleve) may reduce the effects of ACE inhibitors. When taken with lithium (Eskalith, Lithobid), benazepril can increase lithium to toxic levels in the blood.
  • Nitritoid reactions (symptoms include facial flushing, nausea, vomiting and hypotension) may occur when injectable gold (sodium aurothiomalate), used in the treatment of rheumatoid arthritis, is combined with ACE inhibitors, including benazepril.

Is benazepril safe to take if I'm pregnant or breastfeeding?

  • ACE inhibitors, including benazepril, can be harmful to the fetus and should not be taken by pregnant women.
  • A small amount of benazepril is excreted into breast milk. A newborn exclusively breastfed may ingest less than 0.1% of the maternal dose of benazepril.

What else should I know about benazepril?

What preparations of benazepril are available?

Tablets: 5, 10, 20, and 40 mg.

How should I keep benazepril stored?
