Capoten is used for:
Treating high blood pressure or heart failure. It is also used to treat kidney problems caused by diabetes in certain patients.

- you are allergic to any ingredient in Capoten or to any other ACE inhibitor (eg, enalapril), including if you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or hoarseness) caused by an ACE inhibitor
- you are pregnant
- you are taking a medicine that contains aliskiren and you also have diabetes or kidney problems. Check with your doctor or pharmacist if you are not sure if a medicine you take contains aliskiren

Important safety information:
- Capoten may cause dizziness or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use Capoten with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Capoten may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects. If light-headedness occurs, especially during the first few days of treatment, contact your doctor.

- Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
- Capoten may not work as well in black patients. Contact your doctor if your symptoms do not improve or if they become worse.
- Capoten may lower the ability of your body to fight infection. This risk may be greater if you have certain other health problems (eg, kidney problems, collagen vascular disease). Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills.

These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
