Drinking alcohol can further lower your blood pressure and may increase certain side effects of captopril.
Do not use salt substitutes or potassium supplements while taking captopril, unless your doctor has told you to.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
Avoid strenuous exercise without your doctor's approval if you are being treated for heart failure.
