What is Vasotec?
Vasotec (enalapril) is an ACE inhibitor. ACE stands for angiotensin converting enzyme.
Vasotec is used to treat high blood pressure (hypertension) in adults and children who are at least 1 month old.
Vasotec is also used to treat congestive heart failure in adults.
Vasotec is also used to treat a disorder of the ventricles (the lower chambers of the heart that allow blood to flow out of the heart). This disorder can decrease the heart's ability to pump blood to the body.
Do not use Vasotec if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away.
You should not use Vasotec if you have ever had angioedema. Do not take enalapril within 36 hours before or after taking any medicine that contains sacubatril (such as Entresto).
If you have diabetes, do not use enalapril together with any medication that contains aliskiren (Amturnide, Tekturna, Tekamlo).
Enalapril can affect your heart or your electrolyte levels. Call your doctor if you have chest pain, pounding heartbeats or fluttering in your chest, a slow heart rate or weak pulse, a tingly feeling, muscle weakness, or muscle tightness or contraction.
Before taking this medicine
You should not use Vasotec if you are allergic to enalapril, or if you have:
you have a history of angioedema;
recently took a heart medicine called sacubatril; or
if you are allergic to any other ACE inhibitor, such as benazepril, captopril, fosinopril, lisinopril, moexipril, perindopril, quinapril, ramipril, or trandolapril.
Do not take enalapril within 36 hours before or after taking medicine that contains sacubatril (such as Entresto).
If you have diabetes, do not use Vasotec together with any medication that contains aliskiren (such as Tekturna or Tekamlo).
You may also need to avoid taking Vasotec with aliskiren if you have kidney disease.
To make sure Vasotec is safe for you, tell your doctor if you have:
kidney disease (or if you are on dialysis);
a history of blood clot or stroke (including "mini-stroke");
an electrolyte imbalance (such as high levels of potassium in your blood); or
heart disease or congestive heart failure (unless you are taking enalapril for this condition).
Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. Vasotec can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.
Enalapril can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are using Vasotec.
How should I take Vasotec?
Take Vasotec exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
You may take Vasotec with or without food.
Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Your blood pressure will need to be checked often. Your kidney or liver function may also need to be tested.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking Vasotec. This can lead to very low blood pressure, electrolyte disorders, or kidney failure.
If you are being treated for high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.
If you need surgery, tell the surgeon ahead of time that you are using Vasotec.
Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking Vasotec?
Drinking alcohol can further lower your blood pressure and may increase certain side effects of Vasotec.
Do not use salt substitutes or potassium supplements while taking Vasotec, unless your doctor has told you to.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
Vasotec side effects
