Zestril

Zestril is in a group of drugs called ACE inhibitors. ACE stands for angiotensin converting enzyme.
Zestril is used to treat high blood pressure (hypertension), congestive heart failure, and to improve survival after a heart attack.

How to use:
Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results from Zestril. Take each dose with a full glass of water. Zestril can be taken with or without food.

Vomiting, diarrhea, or heavy sweating can cause you to become dehydrated. This can lead to very low blood pressure, electrolyte disorders, or kidney failure while you are taking Zestril. Drink plenty of water each day while you are taking this medication.

To be sure Zestril is helping your condition, your blood pressure will need to be checked on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled visits to your doctor. If you need to have any type of surgery, tell the surgeon ahead of time that you are taking Zestril. You may need to stop using the medicine for a short time. If you are being treated for high blood pressure, keep using Zestril even if you feel fine. High blood pressure often has no symptoms.
