What special precautions should I follow?

Before taking enalapril,

• tell your doctor and pharmacist if you are allergic to enalapril, benazepril (Lotensin), captopril (Capoten), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), trandolapril (Mavik), or any other medications.
• tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: aspirin and other nonsteroidal anti-inflammatory medications (NSAIDs) such as indomethacin (Indocin); diuretics ('water pills'); lithium (Eskalith, Lithobid); and potassium supplements. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• tell your doctor if you have or have ever had heart or kidney disease; lupus; scleroderma; diabetes; or angioedema, a condition that causes difficulty swallowing or breathing and painful swelling of the the face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs.
• tell your doctor if you plan to become pregnant or are breast-feeding.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking enalapril.
• you should know that diarrhea, vomiting, not drinking enough fluids, and sweating a lot can cause a drop in blood pressure, which may cause lightheadedness and fainting.

What special dietary instructions should I follow?

Talk to your doctor before using salt substitutes containing potassium. If your doctor prescribes a low-salt or low-sodium diet, follow these directions carefully.

What should I do if I forget a dose?

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
