Patient Information
Patients should be advised to immediately report to their physician any signs or symptoms suggesting angioedema
(e.g., swelling of face, eyes, lips, tongue, larynx and extremities; difficulty in swallowing or breathing;
hoarseness) and to discontinue therapy.

sign of neutropenia, or of progressive edema which might be related to proteinuria and nephrotic syndrome.
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 with the physician.

salt substitutes without consulting their physician.
