What should I avoid while taking Zestril?

While you're taking Zestril (lisinopril), which is prescribed for high blood pressure and certain heart conditions, you should avoid taking potassium and salt supplements, which may raise potassium in the blood too high. You should also avoid getting gold injections (sometimes used to treat arthritis), because the combination could cause a number of symptoms, including excessively low blood pressure.

You should also avoid operating machinery or driving until you see how lisinopril affects you.
