Angioedema, including laryngeal edema, may occur with treatment with ACE inhibitors, usually occurring early in therapy (within the first month).

Patients should be cautioned that lightheadedness can occur with univasc®, especially during the first few days of therapy. If fainting occurs, the patient should stop taking univasc® and consult the prescribing physician.
All patients should be cautioned that excessive perspiration and dehydration may lead to an excessive fall in blood pressure because of reduction in fluid volume. Other causes of volume depletion such as vomiting or diarrhea may also lead to a fall in blood pressure; patients should be advised to consult their physician if they develop these conditions.
Patients should be told not to use potassium supplements or salt substitutes containing potassium without consulting their physician.
Female patients of childbearing age should be told about the consequences of exposure to univasc® during pregnancy. Discuss treatment options with women planning to become pregnant. Patients should be asked to report pregnancies to their physicians as soon as possible.
