Dose Adjustments

The antihypertensive effect of moexipril may diminish towards the end of the dosing interval. Blood pressure should, therefore, be measured just prior to dosing to determine whether satisfactory blood pressure control is obtained. If control is not adequate, increased dose or divided dosing can be tried.

Monitoring:

• Monitor serum electrolytes periodically.
• Monitor renal function during the first few weeks of therapy.
• Consider monitoring white blood cell counts in patients with collagen vascular disease, especially if the disease is associated with impaired renal function.

Patient advice:

• Advise patients to immediately report any signs or symptoms of angioedema (breathing difficulty or swelling of face, extremities, eyes, lips, or tongue) and to stop taking this drug until consulting a physician.
• Encourage patients to report any lightheadedness that may occur during treatment initiation and to stop taking this drug until consulting a physician.
• Caution patients to consult their physician if excessive perspiration, dehydration, vomiting, or diarrhea occurs as it may lead to excessive blood pressure reduction due to reduced fluid volume.
• Advise patients against using potassium-sparing diuretics, potassium supplements or potassium-containing salt substitutes without consulting their physician.
• Tell patients to promptly report any sign of infection (e.g., sore throat, fever), which may be a sign of neutropenia.
