Information pour les patients
Pregnancy: Female patients of childbearing age should be told about the consequences of second- and
third-trimester exposure to ACE inhibitors, and they should also be told that these consequences do not appear to
have resulted from intrauterine ACE-inhibitor exposure that has been limited to the first trimester. These patients
should be asked to report pregnancies to their physicians as soon as possible.
Angioedema: Angioedema, including laryngeal edema, can occur with treatment with ACE inhibitors,
especially following the first dose. Patients should be so advised and told to report immediately any signs or
symptoms suggesting angioedema (swelling of face, eyes, lips, or tongue, or difficulty in breathing) and to take no
more drug until they have consulted with the prescribing physician.
Symptomatic Hypotension: Patients should be cautioned that lightheadedness can occur, especially
during the first days of therapy, and it should be reported. Patients should be told that if syncope occurs, ramipril
should be discontinued until the physician has been consulted.
All patients should be cautioned that inadequate fluid intake or excessive perspiration, diarrhea, or vomiting can
lead to an excessive fall in blood pressure, with the same consequences of lightheadedness and possible syncope.
Hyperkalemia: Patients should be told not to use salt substitutes containing potassium without
consulting their physician.
Neutropenia: Patients should be told to promptly report any indication of infection (e.g.,
sore throat, fever), which could be a sign of neutropenia.
