Side effect details

Here’s some detail on certain side effects this drug may cause.

Cough

Cough may be a side effect of lisinopril for some people. This was one of the more common side effects reported by people taking the drug in clinical studies.

You may experience coughing within hours of taking your first dose of lisinopril oral tablet. It can also happen months after you start your treatment.

Although it’s not common, some people have stopped taking angiotensin-converting enzyme (ACE) inhibitors such as lisinopril due to a cough that won’t go away.

If you develop a cough while taking lisinopril, talk with your doctor. If the cough won’t go away or is bothering you, your doctor may suggest another medication other than lisinopril to treat your condition.

Increased potassium levels

Some people taking lisinopril oral tablets may have increased potassium levels. This side effect is typically mild, but in rare cases, it can be serious.

People with kidney problems are more likely to have increased potassium levels with lisinopril. This is because having damaged kidneys makes it harder for your body to get rid of potassium.

You may also be more likely to have high potassium levels from taking lisinopril if you:

High potassium levels do not cause symptoms in most people. But in rare cases, you may have symptoms such as:

Your doctor will monitor your potassium levels using blood tests while you’re taking lisinopril. But if you notice any of the symptoms listed above, talk with your doctor right away. This condition can be treated, and treating it sooner can help prevent it from becoming serious.

Gastrointestinal side effects

In rare cases, taking lisinopril can cause some gastrointestinal (digestive) side effects.

Gastrointestinal side effects reported by people taking lisinopril in clinical studies included:

  • constipation
  • diarrhea
  • flatulence (gas)

If you experience gastrointestinal side effects from lisinopril, talk with your doctor or pharmacist. Depending on the side effect, they may recommend treatment.

Gastrointestinal side effects such as constipation, diarrhea, and gas can sometimes be treated using over-the-counter (OTC) medications. But it’s always best to talk with your doctor before you take any medication, including OTC drugs.

Allergic reaction and angioedema

As with most drugs, some people can have an allergic reaction after taking lisinopril oral tablet.

Symptoms of a mild allergic reaction can include:

  • skin rash
  • itchiness
  • flushing (temporary warmth, redness, or deepening of skin color)

A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include:

  • swelling under your skin, typically in your eyelids, lips, hands, or feet
  • swelling of your tongue, mouth, or throat
  • trouble breathing

Taking lisinopril can also cause angioedema, which is severe, sudden swelling that forms under your skin. Symptoms can include:

  • swelling that affects your arms, face, intestines, legs, lips, tongue, voice box, or vocal cords
  • shortness of breath
  • abdominal (belly) pain

In some cases, you may be at higher risk for angioedema while taking lisinopril. For instance, your risk may be increased if you’ve had angioedema in the past that wasn’t caused by taking an ACE inhibitor (such as lisinopril). You may also have a higher risk if you’re Black. Use of ACE inhibitors has been linked with a higher rate of angioedema in Black people than in non-Black people.

Your doctor can tell you more about your risk of angioedema when taking lisinopril

Call your doctor right away if you have any kind of allergic reaction to lisinopril, as the reaction could become severe. Call 911 or your local emergency number if your symptoms feel life threatening or if you think you’re having a medical emergency.

The lisinopril dosage your doctor prescribes will depend on several factors. These include:

  • the type and severity of the condition you’re using lisinopril oral tablet to treat
  • your age
  • side effects from lisinopril you may have
  • other medical conditions you may have or medications you may take

Typically, your doctor will start you on a low dosage. Then they’ll adjust it over time to reach the amount that’s right for you. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect.

The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Drug strengths

Lisinopril oral tablets are available in the following strengths:

  • 2.5 milligrams (mg)
  • 5 mg
  • 10 mg
  • 20 mg
  • 30 mg
  • 40 mg

Dosage for high blood pressure

For treating hypertension (high blood pressure) in adults, the recommended starting dose is 10 mg taken once per day. Depending on your blood pressure readings, your doctor may adjust your dose over time. The typical dosing range is 20 mg to 40 mg taken once daily.

Dosage for adjuvant treatment of heart failure

When lisinopril is used as an adjuvant (add-on) treatment for heart failure, the recommended starting dose is 5 mg taken once per day. But if you have low blood sodium levels, your doctor may have you start with a dose of 2.5 mg taken once a day.

Over time, your doctor will increase your dose. They’ll try to get you to the maximum dose of 40 mg if you don’t have bothersome side effects and if lisinopril seems to be working for you.

Dosage for heart attack

For reducing the risk of death after a heart attack, the recommended starting dosage of lisinopril is 5 mg. You’ll get another 5-mg dose 24 hours later. After another 24 hours, you’ll get one 10-mg dose. You’ll then continue taking 10 mg once per day for at least 6 weeks. Your doctor may prescribe a lower dose of lisinopril if you have hypotension (low blood pressure) after your heart attack.

Children’s dosage

For high blood pressure in children, it’s recommended that treatment starts with a dosage of no more than 5 mg per day. The dose will then be adjusted based on the child’s blood pressure readings, up to a maximum dose of 40 mg per day.

To determine the right lisinopril dose, your child’s doctor will use the child’s weight in kilograms.

What if I miss a dose?

To help make sure you do not miss a dose, try using a medication reminder. This can include setting an alarm or timer on your phone or downloading a reminder app. A kitchen timer can work, too.

Will I need to use this drug long term?

Lisinopril oral tablet is meant to be used as a long-term treatment. If you and your doctor determine that lisinopril oral tablet is safe and effective for you, you’ll likely take it long term.

Here are answers to some frequently asked questions about lisinopril oral tablet.

What’s lisinopril’s classification? Is it a beta-blocker, ACE inhibitor, blood thinner, or diuretic?

Lisinopril is classified as an angiotensin-converting enzyme (ACE) inhibitor. For more information on ACE inhibitors and how lisinopril works, see the “How lisinopril oral tablet works” section below.

Depending on the condition it’s being used to treat, lisinopril may be used with other drugs, including beta-blockers, blood thinners, or diuretics. For more information, see the “Lisinopril oral tablet use with other drugs” section below. You can also talk with your doctor or pharmacist to learn more.

Does lisinopril cause weight loss or weight gain?

No, lisinopril isn’t known to cause weight loss or weight gain. People taking the drug in clinical studies didn’t report weight changes as a side effect.

Unexplained weight loss can be a symptom of liver damage, a very rare but potentially serious side effect of lisinopril. In most cases, weight loss occurs with other symptoms of liver damage. These symptoms can include:

Unexplained weight gain can be a symptom of angioedema, a very rare but potentially serious side effect of lisinopril. Angioedema is the severe, sudden swelling that forms under your skin due to an allergic reaction to lisinopril. Symptoms can include:

  • swelling of the face or mouth
  • shortness of breath
  • abdominal (belly) pain

If you’re concerned about weight changes during your lisinopril treatment, talk with your doctor or pharmacist.

How quickly will lisinopril lower my blood pressure?

Lisinopril begins working to lower your blood pressure after you take your first dose, but you may not notice the drug working in your body. This is because high blood pressure rarely causes symptoms.

In clinical studies, some people had lower blood pressure within 24 hours after taking their first dose. But it may take longer for lisinopril to work for you.

If you have questions about what to expect with your lisinopril treatment, talk with your doctor or pharmacist.

Will lisinopril lower my heart rate?

No, lisinopril should not lower your heart rate. This effect wasn’t seen in clinical studies.

Depending on the condition you’re using lisinopril to treat, other medications you take with lisinopril may lower your heart rate. For example, people with heart failure are usually also prescribed a beta-blocker, which are medications that lower your heart rate.

If you have questions or concerns about how your treatment may affect your heart rate, talk with your doctor or pharmacist.

Can lisinopril interact with grapefruit?

No, lisinopril doesn’t interact with grapefruit.

Depending on the condition you’re using lisinopril to treat, other drugs you take with lisinopril may interact with grapefruit. For example, after a heart attack, most people are also prescribed a statin, which is a medication that lowers your cholesterol. Some statins interact with grapefruit. Your doctor or pharmacist can check for any interactions between the statin you’re prescribed and grapefruit.

If you have other questions about whether grapefruit interacts with any medications you take, talk with your doctor or pharmacist.

Does lisinopril increase the risk of cancer?

It’s not known. More studies are needed to determine whether ACE inhibitors such as lisinopril increase the risk of cancer.

The evidence linking ACE inhibitors to cancer is conflicting. Smaller studies have shown both an increased and a decreased risk of cancer with the use of ACE inhibitors.

If you have concerns about your risk for cancer with lisinopril or any of your other medications, talk with your doctor or pharmacist.

There are no known interactions between lisinopril oral tablets and alcohol.

However, excessive alcohol use can make hypertension (high blood pressure) harder to treat. This is because drinking too much alcohol may raise your blood pressure.

The American Heart Association (AHA) recommends limiting yourself to no more than:

  • one drink per day, in females*
  • two drinks per day, in males*

Although red wine may have some health benefits (including for your heart), it can raise your blood pressure with excessive use. If you drink alcohol, talk with your doctor about how much may be safe for you to drink with your condition and treatment plan.

* Sex and gender exist on spectrums. Use of the terms “male” and “female” in this article refers to sex assigned at birth.

Lisinopril oral tablet can interact with several other medications. It can also interact with certain supplements.

Different interactions can cause different effects. For instance, some interactions can interfere with how well a drug works. Other interactions can increase side effects or make them more severe.

Lisinopril oral tablet and other medications

Below is a list of medications that can interact with lisinopril oral tablet. This list does not contain all drugs that may interact with lisinopril oral tablet.

Before taking lisinopril oral tablet, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and supplements you use. Sharing this information can help you avoid potential interactions.

If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.

You should not take lisinopril with the drug sacubitril, which is found in sacubitril/valsartan (Entresto). Taking sacubitril/valsartan with lisinopril may raise your risk for angioedema, which is severe, sudden swelling that forms under your skin. (To learn more about the risk of angioedema, see the “Allergic reaction and angioedema” section above.)

People taking lisinopril who have diabetes should not take aliskiren with lisinopril. Taking these drugs together raises your risk for side effects from either drug, especially in people with diabetes.

Medications that can interact with lisinopril include:

Lisinopril oral tablet and herbs and supplements

There are no herbs or supplements that have been specifically reported to interact with lisinopril oral tablet. However, you should still check with your doctor or pharmacist before using any of these products while taking lisinopril oral tablet.

Lisinopril oral tablet and foods

There are no foods that have been specifically reported to interact with lisinopril or foods you need to avoid while taking the drug. If you have any questions about eating certain foods with lisinopril, talk with your doctor.

The Food and Drug Administration (FDA) approves prescription drugs such as lisinopril oral tablet to treat certain conditions. Lisinopril may also be used off-label for other conditions. Off-label drug use means using a drug for a purpose other than what it’s been approved for by the FDA.

Lisinopril oral tablet for high blood pressure

Lisinopril is prescribed to treat hypertension (high blood pressure) in adults and in children ages 6 years and older.

Your heart needs a constant supply of blood and oxygen to work correctly. The nutrients your heart needs are supplied by blood vessels, which can stretch and tighten to accommodate more or less fluid.

When your blood vessels tighten, your blood pressure can increase. A hormone made by your body, called angiotensin II, sends signals telling your blood vessels to tighten. In addition, angiotensin II causes your body to hold on to more water and salt, which also raises your blood pressure.

Lisinopril treats high blood pressure by blocking the action of a protein called angiotensin converting enzyme (ACE). By blocking ACE, lisinopril reduces the amount of angiotensin II (a hormone) that your body makes. This can help lower your blood pressure.

Effectiveness for high blood pressure

Clinical studies have found lisinopril to be effective for treating high blood pressure in adults. However, the studies have shown that lisinopril may be less effective at lowering blood pressure in people who are Black.*

If you have questions about how well lisinopril may work for you, talk with your doctor.

For more information on how the drug performed in studies, see lisinopril’s prescribing information.

According to clinical guidelines, ACE inhibitors such as lisinopril are one of four preferred drug classes for treating high blood pressure in most adults. Your doctor can determine which medication will work best for you based on your needs.

* Research has shown that Black people tend to have lower levels of renin, which is an enzyme that helps regulate blood pressure. Lisinopril is an ACE inhibitor. This type of drug helps lower blood pressure by preventing the hormone angiotensin I from being made into another hormone called angiotensin II. Angiotensin I is made by renin, so people with less renin have less angiotensin I to block. As a result, lisinopril may not be as effective at lowering their blood pressure.

Lisinopril oral tablet for adjuvant treatment of heart failure

Lisinopril is approved for use as an adjuvant (add-on) treatment for heart failure in adults.

With heart failure, your heart is no longer able to pump enough blood to supply to your body. When this occurs, your heart may have to work harder to try to pump more blood. This can cause further damage to your heart and make heart failure worse.

Symptoms of heart failure can include:

  • a cough that doesn’t go away
  • shortness of breath
  • swelling in your ankles, abdomen (belly), or legs
  • fatigue (lack of energy)
  • loss of appetite
  • sudden or unexplained weight gain

Lisinopril treats heart failure by widening your blood vessels. This makes it easier for your heart to pump blood through your body. Over time, this can help prevent your heart from working too hard and becoming stiff or enlarged.

Effectiveness for adjuvant treatment of heart failure

Clinical studies have found lisinopril to be effective as an adjuvant treatment of heart failure. For more information on how the drug performed in these studies, see lisinopril’s prescribing information.

Clinical guidelines recommend treatment with an ACE inhibitor such as lisinopril for adults with heart failure. According to these guidelines, using an ACE inhibitor can lower your risk for hospital stays if you have heart failure. In some cases, ACE inhibitors can also lower your risk for death from heart failure.

Lisinopril oral tablet for heart attack

Lisinopril is approved to reduce the risk in adults for dying after a heart attack.

When you have a heart attack, blood flow to certain areas of the heart is cut off. A lack of blood flow can damage your heart, making it weaker and unable to work properly.

Symptoms of a heart attack may include:

  • pain, pressure, or tightness in your chest
  • pain that spreads into your arms, back, neck, or jaw
  • shortness of breath or trouble breathing
  • nausea

Lisinopril works to widen your blood vessels. This means your heart doesn’t have to work as hard to pump blood through your body.

Effectiveness for heart attack

Clinical studies have found lisinopril to be effective for reducing the risk of dying after a heart attack. For more information on how the drug performed in these studies, see lisinopril’s prescribing information.

In addition, clinical guidelines recommend the use of an ACE inhibitor, such as lisinopril, to help reduce the risk of dying after a heart attack.

Lisinopril oral tablet and children

Lisinopril is approved to treat high blood pressure in children ages 6 years and older. Clinical studies have found lisinopril to be effective for this use. For more information on how the drug performed in these studies, see lisinopril’s prescribing information.

Depending on the condition it’s prescribed to treat, you may use lisinopril alone or with other drugs.

For example, for treating hypertension (high blood pressure), you may take lisinopril alone. But in some cases, your doctor may also prescribe another blood pressure medication that works differently than lisinopril, such as hydrochlorothiazide. For some people, using more than one drug works better to treat high blood pressure.

For treating heart failure and for reducing the risk of dying after a heart attack, lisinopril is used with other drugs. Medications commonly used with lisinopril for treating heart failure include beta-blockers, and diuretics. Medications commonly used with lisinopril after a heart attack include beta-blockers, statins, and blood thinners.

If you have questions about using lisinopril with other drugs, talk with your doctor.

Lisinopril is approved by the Food and Drug Administration (FDA) to:

  • treat hypertension (high blood pressure) in adults and in children ages 6 years and older. Lisinopril may be used alone or with other medications for this condition.
  • treat heart failure in adults. For this purpose, lisinopril is given as an add-on treatment with other drugs.
  • reduce the risk in adults for dying after a heart attack. Lisinopril is taken with other drugs for this use.

Lisinopril for high blood pressure

When your blood vessels tighten, your blood pressure can increase. A hormone made by your body, called angiotensin II, sends signals telling your blood vessels to tighten. In addition, angiotensin II causes your body to hold on to more water and salt, which also raises your blood pressure.

Lisinopril’s mechanism of action (the way it works) for treating high blood pressure is that it blocks the action of a protein called angiotensin converting enzyme (ACE). By blocking ACE, lisinopril reduces the amount of angiotensin II your body makes. This can help lower your blood pressure.

Lisinopril for heart failure

With heart failure, your heart is no longer able to pump enough blood to supply to your body. Sometimes, this happens because the heart muscles have become stiff and hard. This can mean that blood flow to the heart may be reduced or even blocked. In other cases of heart failure, the heart may not pump enough blood to support other organs in your body.

When your heart can’t pump enough blood to support your body, it may have to work harder. This can make heart failure worse.

Symptoms of heart failure can include:

  • a cough that doesn’t go away
  • trouble breathing or shortness of breath
  • swelling in your ankles, abdomen (belly), or legs
  • fatigue (lack of energy)
  • loss of appetite
  • sudden or unexplained weight gain

Lisinopril works to treat heart failure by widening your blood vessels. This makes it easier for your heart to pump blood through your body. Over time, this can help prevent your heart from working too hard and becoming stiff or enlarged.

With a heart attack, blood flow to certain areas of the heart is cut off. A lack of blood flow can damage your heart, making it weaker and unable to work properly.

Symptoms of a heart attack may include:

  • pain, pressure, or tightness, in your chest
  • pain that spreads into your arms, back, neck, or jaw
  • shortness of breath or difficulty breathing
  • nausea

Lisinopril works to widen your blood vessels. This means your heart doesn’t have to work as hard to pump blood through your body. This helps your heart heal after a heart attack and prevents it from working too hard.

How long does it take to work?

Lisinopril begins working as soon as you take your first dose, but you may not notice the drug working in your body. This is because high blood pressure rarely causes symptoms.

For treating high blood pressure, many people in clinical studies had their blood pressure lowered within 1 hour of taking their first dose.

When used after a heart attack, studies have shown that ACE inhibitors such lisinopril reduce the risk of dying as soon as 24 hours after the first dose.

If you have other questions about how long it takes lisinopril to work, talk with your doctor or pharmacist.

How long does it stay in your system?

Lisinopril stays in your system for about 48 to 60 hours.

Lisinopril’s half-life is about 12 hours. (A drug’s half-life is the amount of time it takes for your body to remove half a dose from your system.) The half-life may be longer in people with kidney problems. Normally a drug is cleared from your system in four to five half-lives.

Other drugs are available that can treat your condition. Some may be a better fit for you than others. If you’re interested in finding an alternative to lisinopril oral tablets, talk with your doctor. They can tell you about other medications that may work well for you.

Note: Some of the drugs listed here are used off-label to treat these specific conditions. Off-label drug use means using a drug for a purpose other than what it’s been approved for by the FDA.

Alternatives for high blood pressure

Examples of other drugs that may be used to treat hypertension (high blood pressure) include:

Alternatives for treatment of heart failure

Examples of other drugs that may be used as treatment for heart failure include:

  • another ACE inhibitor, such as ramipril (Altace)
  • an ARB, such as losartan (Cozaar) or valsartan (Diovan)
  • certain beta-blockers, including:
    • carvedilol (Coreg)
    • metoprolol succinate (Toprol XL)
  • an aldosterone receptor antagonist, such as spironolactone (Aldactone) or eplerenone (Inspra)
  • dapagliflozin (Farxiga)
  • ivabradine (Corlanor)
  • sacubitril/valsartan (Entresto)
  • digoxin (Lanoxin)
  • hydralazine/isosorbide dinitrate

Alternatives for heart attack

Examples of other drugs that may be used after a heart attack include:

  • another ACE inhibitor, such as ramipril (Altace)
  • an ARB, such as losartan (Cozaar) or valsartan (Diovan)
  • certain beta-blockers, including:
    • bisoprolol
    • carvedilol (Coreg)
    • metoprolol succinate (Toprol XL)
  • drugs to prevent blood clots, such as aspirin or clopidogrel (Plavix)

You should take lisinopril oral tablets according to the instructions your doctor or other healthcare professional gives you.

Lisinopril oral tablets are taken by mouth.

When to take

Regardless of the condition it’s used to treat, lisinopril is typically taken once per day. There is no best time to take lisinopril. You can take your dose at any time of day. But it may be helpful to take lisinopril around the same time each day (for example, with breakfast) to make it part of your daily routine.

To help make sure you do not miss a dose, try using a medication reminder. This can include setting an alarm or timer on your phone or downloading a reminder app. A kitchen timer can work, too.

Taking lisinopril oral tablets with food

You may take lisinopril with or without food.

Can lisinopril oral tablets be crushed, split, or chewed?

It depends. In most cases, the tablets may be crushed, split, or chewed.

But there are several manufacturers of lisinopril oral tablets. To make sure the lisinopril tablets you’re prescribed can be crushed, split, or chewed, talk with your pharmacist or doctor first.

If your tablets can’t be crushed, split, or chewed, your doctor or pharmacist can recommend other treatments that may be easier for you to take. This may include other forms of lisinopril.

Do not use more Lisinopril oral tablet than your doctor recommends. For some drugs, doing so may lead to unwanted side effects or overdose, such as hypotension (low blood pressure).

What to do in case you take too much lisinopril oral tablet

If you think you’ve taken too much of this drug, call your doctor. You can also call the American Association of Poison Control Centers at 800-222-1222 or use their online tool. But if your symptoms are severe, call 911 or your local emergency number, or go to the nearest emergency room right away.

This drug comes with several precautions.

FDA warning: Risks if used during pregnancy

Lisinopril has a boxed warning. This is the most serious warning from the Food and Drug Administration (FDA). A boxed warning alerts doctors and patients about drug effects that may be dangerous.

Risks if used during pregnancy. Drugs such as lisinopril can cause harm to a fetus or miscarriage if used during pregnancy. For this reason, you should not take lisinopril while pregnant, and you should stop taking lisinopril if you become pregnant during your treatment. If you’re pregnant or planning to become pregnant, talk with your doctor about safer options for treating your condition.

If you become pregnant while taking lisinopril, it’s very important that you tell your doctor right away. They’ll have you stop taking the drug, and they can recommend other treatments instead.

Contraindications to lisinopril oral tablet

Lisinopril oral tablets also have some contraindications (conditions or factors that would prevent you from taking the medication). Contraindications for lisinopril include:

If you have any of these factors, you should not use lisinopril. Ask your doctor about other treatment options that might work well for you.

Other precautions

Before taking Lisinopril oral tablets, talk with your doctor about your health history. Lisinopril may not be right for you if you have certain medical conditions or other factors affecting your health. These include:

  • Heart problems. Before you take lisinopril, tell your doctor about any heart problems you may have. Although lisinopril is used to treat some heart problems, other heart problems could raise your risk for side effects from lisinopril. Examples of these side effects include low blood pressure and low sodium levels. Your doctor can determine if lisinopril is safe for you to take.
