About Vasotec

VASOTEC is available only on prescription from your physician.

What Vasotec is used for

VASOTEC is used for:

  • reducing high blood pressure

When blood pressure is high, the workload of the heart and arteries increases so that over time, these organs may not function as they should. In turn, this could lead to damage of the “vital organs”: brain—heart—kidneys, and result in stroke, heart failure, heart attack, blood vessel disease or kidney disease.

VASOTEC is used for:

  • treating patients with heart failure

VASOTEC may also be used to treat patients with heart failure. This is a condition where the heart cannot pump adequate amounts of blood to satisfy the needs of the body.

If your physician has recommended a particular diet, for instance—less salt—follow the diet carefully. This could help your medicine to better control your blood pressure. Your physician may also recommend weight loss. Do follow these suggestions.

What Vasotec does

VASOTEC is part of a class of medicines known as angiotensin converting enzyme (ACE) inhibitors. They lower blood pressure by specifically blocking a naturally occurring substance called angiotensin II. Angiotensin II normally tightens your blood vessels. VASOTEC allows them to relax and therefore help lower high blood pressure.

This medicine does not cure high blood pressure, but does help control it. So, it is important to continue taking the tablets regularly to keep your blood pressure down. You may have to take high blood pressure medicine for life.

Keep your regular appointments with your physician, even if you feel well. High blood pressure may not be easily recognized by you, because you may not “feel any symptoms”; but your physician can measure your blood pressure very easily, and check how the medicine is controlling it.

Read the following information carefully. If you need any explanations, or further information, ask your physician or pharmacist.

  • are allergic to enalapril or any other component of VASOTEC (see What the important nonmedicinal ingredients are:)

  • have a history of swelling of the face, lips, tongue, throat, or sudden difficulty breathing or swallowing.

Warnings and Precautions

Serious Warnings and Precautions

VASOTEC should not be used during pregnancy. If you discover that you are pregnant while taking VASOTEC, stop the medication and please contact your physician as soon as possible.

This medicine may not be suitable for certain people. Tell your physician or pharmacist if you think any of the following applies to you:

  • You have previously taken VASOTEC or other medication of the same type—Angiotensin Converting Enzyme (ACE) inhibitors such as enalapril, lisinopril, captopril, and you were allergic or reacted badly to it, particularly if you experienced swelling of the face, lips, tongue, or throat, or had sudden difficulty breathing or swallowing. These are symptoms of conditions called hereditary angioedema or idiopathic angioedema.

  • You should not take this medicine if you have been diagnosed with hereditary angioedema or idiopathic angioedema (angioedema of unknown cause).

  • Dizziness or drowsiness may occasionally occur when taking medication to lower blood pressure. Therefore, before you perform tasks which may require special attention (driving a car or operating dangerous machinery), wait until you know how you respond to your medicine.

  • You should be aware that black patients are at increased risk of these types of reactions to ACE inhibitors.

  • You are pregnant, breast-feeding or thinking of becoming pregnant. Taking VASOTEC during pregnancy can cause injury and even death to your developing baby. This medicine should not be used during pregnancy. If you become pregnant while taking VASOTEC, stop the medication and report to your physician as soon as possible. It is possible that VASOTEC passes into breast milk. You should not breast-feed while taking VASOTEC.

  • You suffer from low blood pressure (you may notice this as faintness or dizziness, especially when standing).

  • You are undergoing dialysis

  • You have any of these conditions:

    • diabetes

    • heart or blood vessel disease

    • liver disease

    • kidney disease

  • You are receiving gold (sodium aurothiomalate) injections.

  • You are taking “water pills” or potassium supplements.

  • You use potassium containing salt substitutes with your food.

You should also inform your physician or pharmacist if you have recently suffered from excessive vomiting or diarrhea.

If you have diabetes and are taking oral medicines to treat diabetes or insulin, you should closely monitor for low blood glucose levels, especially during the first month of treatment with VASOTEC.

If you have to undergo any dental or other surgery, inform the dentist or the physician in charge that you are taking this medicine.

Remember: This medicine is prescribed for the particular condition that you have. Do not give this medicine to other people, nor use it for any other condition.

Do not use outdated medicine.

Interactions with Vasotec

Do not take any other medicines unless you have discussed the matter with your physician or pharmacist. Certain medications tend to increase your blood pressure, for example, non-prescription preparations for appetite control, asthma, colds, coughs, hay fever and sinus problems, or may also react badly with VASOTEC.

Your physician or pharmacist also needs to know if you are taking any other medication, whether on prescription or otherwise. It is particularly important to inform your physician or pharmacist if you are taking:

  • Diuretics or “water pills”; any other medicines to reduce blood pressure.

  • Diabetes medicine and/or insulin.

  • Potassium-containing medicines, potassium supplements.

  • Salt substitutes that contain potassium, as these may lead to increased levels of potassium in the blood which can be serious. In these cases, your physician may need to adjust the dosage of VASOTEC or monitor your blood level of potassium.

  • Lithium (a drug used to treat a certain kind of depression).

  • Certain pain and arthritis medicines, including gold therapy and non-steroidal anti-inflammatory drugs.
