Your doctor will tell you how many tablets you need to take each day. This depends

Take ZESTRIL only when prescribed by your doctor.
For high blood pressure:
For most patients, the usual starting dose is 5 mg to 10 mg taken once a day.

Depending on your response, this dose may need to be increased.

Things that would be helpful for your blood pressure or heart failure
Some self help measures suggested below may help your condition. Talk to your doctor
or pharmacist about these measures and for more information.
Diet - eat a healthy diet, which includes plenty of fresh vegetables, fruit, bread,
cereals and fish. Also eat less fat and sugar.
Exercise - regular exercise helps to reduce blood pressure and helps the heart get
fitter, but it is important not to overdo it. Walking is good exercise, but try to
find a route that is fairly flat. Before starting any exercise, ask your doctor about
the best kind of programme for you.
Salt - your doctor may advise you to watch the amount of salt in your diet. To reduce
your salt intake you should avoid using salt in cooking or at the table.
Smoking - your doctor may advise you to stop smoking or at least cut down.
Weight - your doctor may suggest losing some weight to help lower your blood pressure
and help lessen the amount of work your heart has to do. Some people may need a dietician's
help to lose weight.
