Vasotec (generic name: enalapril; also known by brand names such as Renitec, BQL, Benalipril, Amprace, Alphapril, Converten, Enalagamma, Enatec, Envas, Invoril, Xanef) is an angiotensin-converting enzyme (ACE) inhibitor used widely to treat high blood pressure (hypertension) and heart failure. By relaxing blood vessels, Vasotec lowers blood pressure, decreases strain on the heart, and helps the heart pump more efficiently. In people with symptomatic heart failure and in some with asymptomatic left ventricular dysfunction, enalapril has been shown to improve symptoms, reduce hospitalizations, and, in certain populations, improve survival when used as part of guideline-directed therapy.
How Vasotec (enalapril) works
Enalapril is a prodrug that your body converts to enalaprilat, its active form. Enalaprilat inhibits the angiotensin-converting enzyme (ACE), a key step in the renin-angiotensin-aldosterone system (RAAS). Blocking ACE reduces production of angiotensin II (a hormone that narrows blood vessels) and aldosterone (a hormone that causes the kidneys to retain salt and water). The result is vasodilation, lower blood pressure, reduced afterload and preload on the heart, and improved cardiac output. ACE inhibitors also increase bradykinin levels, which can further dilate blood vessels but may contribute to the well-known ACE inhibitor cough in some patients.
Who can benefit from Vasotec
Vasotec is prescribed for several cardiovascular indications:
- Hypertension: As first-line or add-on therapy to help achieve blood pressure goals and reduce the risk of stroke, heart attack, and kidney disease.
- Heart failure: To improve symptoms such as breathlessness and fatigue, decrease hospitalizations, and support long-term outcomes when combined with other heart-failure therapies.
- Left ventricular dysfunction: In selected patients with asymptomatic reduced ejection fraction, to delay progression to symptomatic heart failure.
- Kidney protection in certain patients: Although labeling varies, ACE inhibitors like enalapril are often used to help protect kidney function in people with diabetes and albuminuria or in other proteinuric kidney diseases, under clinician guidance.
Vasotec may be used alone or with other blood pressure medications such as thiazide diuretics, calcium channel blockers, beta-blockers, or mineralocorticoid receptor antagonists, depending on your clinical needs and guideline recommendations.
Recommendations
Follow the directions for using this medicine provided by your doctor. Take Vasotec exactly as directed. Do not change your dose or stop the medicine without discussing it with your healthcare provider, even if you feel well. Hypertension often has no symptoms, and consistent therapy is essential.
General adult dosing guidance:
- Hypertension: A common starting dose is 5 mg once daily. Some people, especially those taking a diuretic, may start at 2.5 mg to limit the risk of first-dose low blood pressure. The dose may be titrated based on response and tolerability, typically to 10–40 mg per day, given once daily or divided into two doses.
- Heart failure or asymptomatic left ventricular dysfunction: A typical starting dose is 2.5 mg once or twice daily, with gradual titration as tolerated. Many patients benefit from 10–20 mg total daily dose, given once daily or in two divided doses. Slow up-titration helps minimize dizziness or hypotension.
Special dosing situations:
- Patients on diuretics or with volume depletion: Consider starting at 2.5 mg or temporarily reducing the diuretic to avoid low blood pressure. Your clinician will advise you.
- Kidney impairment: Lower starting doses and slower titration are usually recommended. Dosing adjustments are based on estimated glomerular filtration rate (eGFR) and clinical response.
- Older adults: Start low, go slow. Older individuals may be more sensitive to blood pressure changes and electrolyte shifts.
- Pediatric hypertension: For children who are candidates for ACE inhibitors, dosing is weight-based. Pediatric use should be guided strictly by a pediatrician or pediatric cardiologist.
Administration tips:
- Take Vasotec at the same time each day, with or without food.
- If you miss a dose, take it when you remember unless it's close to your next scheduled dose. Do not double up.
- Overdose can cause significant low blood pressure and other complications. Seek emergency care if too much is taken.
What to expect when starting Vasotec
Some people notice dizziness, lightheadedness, or fatigue when beginning therapy—especially after the first few doses or when the dose increases. These effects often improve as your body adjusts. You should check your blood pressure at home, particularly during the first couple of weeks and after dose changes, and keep a log to share with your clinician.
Most patients do not experience significant side effects. However, call your healthcare provider promptly if you notice persistent cough, swelling of the face or throat, fainting, decreased urination, unusual heartbeat, or severe nausea and abdominal pain.
Precautions
Tell your doctor before taking Vasotec if:
- You are allergic to enalapril, other ACE inhibitors, or any ingredient in the tablet.
- You have diabetes or kidney problems, including a history of kidney transplant or renal artery stenosis.
- You are pregnant, trying to conceive, or breast-feeding.
- You have ever had angioedema (swelling of the face, lips, tongue, or throat), whether related to a prior ACE inhibitor or not.
- You are taking a diuretic (water pill), potassium supplements, salt substitutes containing potassium, or potassium-sparing diuretics like spironolactone or eplerenone.
- You are taking aliskiren, an angiotensin receptor blocker (ARB), sacubitril/valsartan, lithium, or regular nonsteroidal anti-inflammatory drugs (NSAIDs).
First-dose hypotension can occur, especially if you are dehydrated, on high-dose diuretics, or have heart failure. Your clinician may adjust other medicines or recommend starting enalapril at a lower dose.
Contraindications and boxed warnings
- Do not use in pregnancy. ACE inhibitors can harm or be fatal to an unborn baby, particularly in the second and third trimesters. If you become pregnant, stop enalapril and contact your clinician immediately.
- Do not use if you have a history of ACE inhibitor–associated angioedema or hereditary/idiopathic angioedema.
- Do not combine with aliskiren in patients with diabetes due to increased risk of kidney problems, high potassium, and low blood pressure.
Common and serious side effects
Most side effects are mild and manageable. Not everyone experiences them.
- Common: Dry cough, dizziness or lightheadedness, fatigue, headache, nausea, rash.
- Laboratory changes: Increased potassium (hyperkalemia), small rises in creatinine, especially after initiation or dose increases.
- Less common but serious: Angioedema (rapid swelling of the face, lips, tongue, or throat), severe hypotension, acute kidney injury, liver problems (rare), low white blood cell counts (rare), and severe allergic reactions.
Seek emergency care for signs of angioedema, difficulty breathing, or fainting. Notify your clinician promptly if you have persistent cough that bothers you, new swelling, reduced urination, irregular heartbeat, or yellowing of the skin or eyes.
Drug interactions to know
- Potassium-sparing diuretics and supplements: Spironolactone, eplerenone, amiloride, triamterene, and potassium supplements or salt substitutes can raise potassium to dangerous levels when combined with ACE inhibitors. Regular monitoring is essential.
- Diuretics: May increase the risk of first-dose hypotension. Your clinician may adjust diuretics before starting enalapril.
- NSAIDs: Ibuprofen, naproxen, and similar drugs can reduce the blood pressure–lowering effect and increase the risk of kidney problems. Use the lowest effective dose for the shortest duration if needed and discuss with your clinician.
- Lithium: ACE inhibitors can increase lithium levels and toxicity. Avoid or monitor closely.
- Dual RAAS blockade: Combining ACE inhibitors with ARBs or aliskiren is generally discouraged due to limited additional benefit and higher risks of kidney injury and hyperkalemia.
- Sacubitril/valsartan: Do not take with an ACE inhibitor. Allow at least a 36-hour washout between stopping enalapril and starting sacubitril/valsartan (and vice versa) to reduce angioedema risk.
- Injectable gold (sodium aurothiomalate): Rare nitritoid reactions (flushing, nausea, hypotension) have been reported when combined with ACE inhibitors.
Monitoring and follow-up
Baseline and periodic monitoring helps ensure safety and effectiveness:
- Blood pressure and heart rate at home and during visits.
- Kidney function (serum creatinine, eGFR) and electrolytes (especially potassium) at baseline, 1–2 weeks after starting or changing dose, and at intervals thereafter.
- Symptoms: Dizziness, cough, swelling, changes in urination, or fatigue.
In heart failure, clinicians may also track body weight, swelling, exercise tolerance, and NT-proBNP in certain cases. Routine follow-up ensures the dose is optimized for both blood pressure control and heart protection.
Special populations: pregnancy, breastfeeding, and older adults
- Pregnancy: Enalapril is contraindicated. If pregnancy is planned or confirmed, alternative blood pressure medicines with better safety profiles in pregnancy should be used.
- Breastfeeding: Enalapril and enalaprilat are present in breast milk in low amounts. Some guidelines consider enalapril compatible with breastfeeding for healthy term infants, but discuss individual risks and benefits with your clinician, particularly for preterm infants or newborns with kidney issues.
- Older adults: Start with lower doses and titrate slowly. Monitor closely for hypotension, kidney function changes, and electrolyte imbalances.
Lifestyle and complementary strategies
Medication works best when paired with heart-healthy habits:
- Follow a balanced, low-sodium diet such as the DASH eating pattern.
- Engage in regular physical activity as advised by your clinician.
- Limit alcohol, avoid tobacco, and maintain a healthy weight.
- Manage sleep apnea if present, reduce stress, and prioritize restorative sleep.
How to take Vasotec safely
- Take exactly as prescribed, at the same time each day.
- Rise slowly from sitting or lying positions to reduce dizziness.
- Avoid salt substitutes containing potassium unless your clinician approves.
- Tell every healthcare professional you see that you take an ACE inhibitor.
- If you experience swelling of the face, lips, tongue, or throat, stop the medication and seek emergency care immediately.
Comparisons and alternatives
ACE inhibitors as a class (including lisinopril, ramipril, benazepril, and others) share similar benefits and side effect profiles. Choice depends on availability, dosing preferences, and individual response. For patients who cannot tolerate ACE inhibitors due to cough or angioedema, ARBs (such as losartan, valsartan) are common alternatives. In heart failure, enalapril is a foundational therapy, but other agents—including beta-blockers, mineralocorticoid receptor antagonists, SGLT2 inhibitors, and in suitable patients ARNI therapy (sacubitril/valsartan)—are often layered for optimal outcomes under guideline-directed care.
Storage and handling
- Store tablets at room temperature, away from moisture and heat.
- Keep in the original container with the lid tightly closed.
- Keep out of reach of children and pets.
- Do not use after the expiration date printed on the package.
Ingredients
Active ingredient: enalapril maleate. Inactive ingredients vary by manufacturer; check the package insert if you have specific allergies or intolerances to excipients.
Recognizing when to seek medical help
- Emergency: Swelling of face/tongue/throat, severe shortness of breath, fainting, chest pain.
- Urgent: Marked dizziness, sustained low blood pressure readings with symptoms, little or no urination, severe diarrhea or vomiting leading to dehydration, irregular heartbeat.
- Routine: Persistent cough, mild dizziness, questions about side effects or interactions, or if you plan to become pregnant.
Cost, access, and generic options
Enalapril is widely available as a generic, which can reduce cost compared with brand-name Vasotec. Prices vary by pharmacy, dosage, and insurance coverage. Many patients also qualify for savings through pharmacy discount programs. If cost is a barrier, discuss options with your clinician or pharmacist, including generics, tier exceptions, or therapeutic alternatives.
Putting it all together
For many people, Vasotec is a cornerstone therapy for hypertension and heart failure. It works by relaxing blood vessels and reducing the heart’s workload, with clear evidence for symptom relief and long-term cardiovascular protection. Most patients tolerate enalapril well; careful selection, gradual dose titration, and routine monitoring of kidney function and potassium help keep therapy safe and effective. A shared plan with your healthcare team—paired with lifestyle changes—goes a long way toward protecting your heart and kidneys.

Vasotec FAQ
What is Vasotec (enalapril) and what conditions does it treat?
Vasotec is the brand name for enalapril, an ACE inhibitor used to lower high blood pressure, treat heart failure, and help people with asymptomatic left-ventricular dysfunction. It may also slow kidney disease progression in patients with diabetes or proteinuria.
How does Vasotec work?
It blocks the angiotensin-converting enzyme, reducing angiotensin II and aldosterone. This relaxes blood vessels, lowers blood pressure, decreases afterload, and reduces harmful remodeling in heart failure.
How quickly does Vasotec start working and how long does it last?
Blood pressure starts to drop within about one hour, with peak effect in 4–6 hours. Full steady-state benefit builds over 1–2 weeks, and one dose generally lasts 24 hours, though some people need twice-daily dosing.
What are the usual adult doses of Vasotec?
For hypertension, many start at 5 mg once daily, titrating to 10–40 mg per day in one or two doses. For heart failure or frail patients, lower starting doses (for example 2.5 mg) are used and titrated under medical supervision, especially if on diuretics or with kidney impairment.
What common side effects should I expect with Vasotec?
Dizziness, fatigue, headache, and a dry, persistent cough are common. Lab changes can include a small rise in creatinine and higher potassium.
What serious side effects require urgent care?
Swelling of the face, lips, tongue, or throat (angioedema), fainting, severe lightheadedness, little or no urine, or signs of very high potassium such as muscle weakness or palpitations need immediate medical attention.
Who should not take Vasotec?
Do not use it during pregnancy or if you have a history of ACE inhibitor–related angioedema. It should be avoided with aliskiren in people with diabetes and used cautiously in bilateral renal artery stenosis or severe kidney impairment.
Does Vasotec cause cough, and what can be done about it?
A dry cough occurs in a minority of users due to bradykinin buildup. If it is bothersome, your clinician may confirm the cause and consider switching you to an ARB, which is less likely to cause cough.
Can Vasotec affect my kidneys?
A modest increase in creatinine (up to about 30% from baseline) can occur when starting and is often acceptable. Larger rises or sudden changes warrant evaluation for dehydration, drug interactions, or renal artery stenosis.
Does Vasotec increase potassium levels?
Yes, ACE inhibitors can raise potassium, especially when combined with potassium supplements, salt substitutes, potassium-sparing diuretics, or in kidney disease. Regular blood tests help keep potassium in a safe range.
What monitoring is recommended while taking Vasotec?
Blood pressure at home, kidney function (creatinine, eGFR), and potassium should be checked after starting or dose changes and periodically thereafter. People on diuretics, older adults, and those with CKD may need closer follow-up.
Can I stop Vasotec abruptly?
It is not addictive, but stopping suddenly can let blood pressure rebound or worsen heart failure control. Discuss any changes with your clinician and taper only if advised.
What drugs interact with Vasotec?
NSAIDs can blunt its effect and strain the kidneys, while diuretics, alcohol, or other antihypertensives can amplify low blood pressure. Lithium levels may rise, potassium-raising agents increase hyperkalemia risk, and do not combine with ARBs or ARNIs without guidance; a 36-hour washout is required before starting sacubitril/valsartan.
Does Vasotec protect the kidneys in diabetes?
In people with diabetes and albuminuria (protein in urine), ACE inhibitors like enalapril can slow kidney damage and reduce proteinuria. They also help protect the heart in high-risk patients.
How should I take and store Vasotec?
Take it at the same time each day, with or without food, and if you miss a dose, take it when remembered unless it is near the next dose. Store tablets at room temperature away from moisture and heat, and keep out of children’s reach.
Can I drink alcohol while taking Vasotec?
Alcohol can intensify Vasotec’s blood-pressure–lowering effect and cause dizziness or fainting, especially when starting or after dose increases. If you drink, do so moderately and see how your body responds; avoid binge drinking.
Is Vasotec safe during pregnancy?
No. Enalapril carries a boxed warning for fetal toxicity, especially in the second and third trimesters, and should be stopped as soon as pregnancy is detected. Use effective contraception and discuss safer alternatives if planning pregnancy.
Can I take Vasotec while breastfeeding?
Small amounts of enalapril/enalaprilat enter breast milk, and most guidelines consider it compatible in healthy, full-term infants. Premature or medically fragile infants may need alternative therapy; discuss with your pediatrician.
Should I stop Vasotec before surgery or anesthesia?
Many clinicians advise holding the dose the night before or morning of major surgery to reduce the risk of intraoperative low blood pressure, especially if you take it only for hypertension. Follow your surgeon and anesthesiologist’s instructions for your situation.
What if I develop vomiting, diarrhea, or become dehydrated while on Vasotec?
Dehydration can magnify kidney strain and low blood pressure with ACE inhibitors. Use “sick day” rules: temporarily pause Vasotec and potassium-raising drugs until you are eating and drinking normally, then restart as advised.
Can I use over-the-counter pain relievers with Vasotec?
Occasional acetaminophen is preferred. Regular use of NSAIDs like ibuprofen or naproxen may reduce Vasotec’s benefits and harm the kidneys, particularly in older adults or those on diuretics; ask your clinician before using them.
Are potassium supplements or salt substitutes safe with Vasotec?
They can push potassium too high when combined with ACE inhibitors. Avoid them unless specifically prescribed and monitored.
Do vaccines or grapefruit interact with Vasotec?
Routine vaccines are safe and effective while on enalapril. Grapefruit does not have a clinically meaningful interaction with Vasotec.
How does Vasotec compare to lisinopril?
Both are ACE inhibitors with similar efficacy for blood pressure and heart protection. Enalapril is a prodrug converted to enalaprilat and may be taken once or twice daily; lisinopril is long-acting and usually once daily—choice often depends on response, side effects, and dosing preference.
Vasotec vs ramipril: which is better?
Both lower blood pressure and reduce cardiovascular risk; ramipril has strong outcome data in high-risk patients (HOPE), while enalapril has robust heart failure data (SOLVD). In practice, effectiveness and tolerability are similar, so selection is individualized.
Vasotec vs benazepril: any differences?
Efficacy and side-effect profiles are comparable as ACE inhibitors. Benazepril is often once daily and available in fixed-dose combos with amlodipine; enalapril may need twice-daily dosing for some patients.
Vasotec vs quinapril: which lasts longer?
Both can provide 24-hour control, but some patients experience smoother coverage with quinapril once daily, while others do well on enalapril twice daily. Blood pressure monitoring helps decide dosing frequency.
Vasotec vs perindopril: does one protect the heart more?
Perindopril has outcome data in stable coronary disease (EUROPA), while enalapril’s strengths include heart failure and hypertension. Overall cardioprotection is comparable when blood pressure is controlled.
Vasotec vs captopril: why pick one over the other?
Captopril is short-acting and usually taken two to three times daily, with more taste disturbances and rash. Enalapril is longer-acting and generally more convenient for chronic use.
Vasotec vs fosinopril: which is safer in kidney disease?
Fosinopril has dual hepatic and renal elimination, which can be advantageous in advanced CKD. Enalapril relies more on renal clearance and often requires dose adjustment; both still need close monitoring.
Vasotec vs trandolapril: are side effects different?
Side effects typical of ACE inhibitors—cough, dizziness, hyperkalemia, rare angioedema—are similar. Trandolapril is long-acting and once daily, while enalapril dosing may vary.
Vasotec vs losartan (an ARB): which causes less cough?
ARBs like losartan do not increase bradykinin and have a much lower risk of cough. If cough is troublesome on enalapril, many patients switch to an ARB with similar blood-pressure and kidney benefits.
Vasotec vs valsartan: how do they differ?
Both lower blood pressure and protect the heart and kidneys; valsartan is an ARB with minimal cough risk and similar efficacy. Choice depends on side effects, comorbidities, and clinician preference.
Is any ACE inhibitor proven best for heart failure?
Multiple ACE inhibitors, including enalapril, have strong heart failure evidence, and class effects are considered comparable when target doses are reached. The key is titration to guideline-recommended doses as tolerated.
How do I switch from Vasotec to another ACE inhibitor?
There is no exact milligram-for-milligram conversion across the class. Clinicians choose a reasonable starting dose of the new drug, monitor blood pressure, kidney function, and potassium, and adjust based on response.
