Does Lisinopril Cause ED?
Lisinopril is a medicine that doctors often give to people who have high blood pressure or heart problems. Many people wonder if it can cause erectile dysfunction (ED), which is when someone has trouble getting or keeping an erection. Most doctors and medical sources say that lisinopril usually doesn’t cause ED. In fact, it can actually help improve ED in people who have high blood pressure, because it helps blood flow better through the body, including to the penis. If someone does have ED after starting lisinopril, it usually goes away after a few weeks.
In rare cases, lisinopril might cause ED if it lowers a person’s blood pressure too much. When blood pressure gets too low, it can affect how well the body works during an erection. But compared to older blood pressure medicines like beta-blockers and water pills, lisinopril and other ACE inhibitors are less likely to cause ED. That’s why doctors often choose these kinds of medications for people who are worried about their sexual health.
Even though most reports say lisinopril doesn’t usually cause ED, some studies where patients answered questions showed a bit more sexual problems than doctors usually hear about. This means some cases might not get reported during regular check-ups. If someone notices a new or worse ED while taking lisinopril, it’s important to talk to a doctor. ED can happen for many reasons, other medicines, health problems, or even stress, and not just because of lisinopril.
The main benefit of lisinopril is that it helps control high blood pressure, which on its own can cause ED over time by damaging blood vessels. By helping blood vessels relax and improving blood flow, lisinopril may actually help ED in many people.
What Is Lisinopril and How Does It Work?
Lisinopril is a medicine in a group called ACE inhibitors. It’s mainly used to treat high blood pressure, help people who have heart failure, and support recovery after a heart attack.
Lisinopril works by blocking a chemical in the body called angiotensin-converting enzyme (ACE). This enzyme helps make another chemical that tightens blood vessels. When lisinopril blocks ACE, it helps blood vessels relax and get wider. This lowers blood pressure and lets more blood flow through the body.
Lisinopril also helps keep another chemical, called bradykinin, from breaking down too fast. Bradykinin helps the body make nitric oxide, which relaxes muscles in the penis to help with erections. Because of these effects, lisinopril can help the heart and blood flow. People usually take it once a day, as a tablet or liquid.
Erectile Dysfunction (ED): What It Is and How It Connects to High Blood Pressure?
Erectile dysfunction, or ED, means a person has trouble getting or keeping an erection strong enough for sexual activity. It’s very common, especially as men get older. In the United States, about 30 million men have ED. By the time men are between 40 and 70 years old, around half of them will experience some form of ED.
There is a strong connection between high blood pressure (also called hypertension) and ED. High blood pressure damages the inside walls of blood vessels and makes them stiff and narrow. This makes it harder for blood to flow properly, including to the penis. Blood flow is key for getting an erection, so if it’s blocked or reduced, ED can happen. Also, high blood pressure can make the muscles in the penis too stiff to relax and let blood in during sexual arousal.
In fact, ED is sometimes one of the first signs of heart problems, including high blood pressure. Studies show that 35% to 40% of men with high blood pressure also have ED. The arteries in the penis are very small, so they are often the first to be affected by health problems like high blood pressure. If these small arteries are damaged, it could mean bigger arteries, like the ones in the heart or brain, are also at risk.
That’s why when a man has ED, especially if he hasn’t had heart issues before, doctors should check his overall heart health. They might test his blood pressure, cholesterol, and blood sugar to find out if there are any hidden problems that need treatment.
Is ED a Usual Side Effect of Lisinopril?
Lisinopril is a common medicine used to treat high blood pressure. Most people taking lisinopril don’t have problems with their sexual health. In fact, lisinopril is usually thought to be safe in this area.
However, some official drug guides mention that lisinopril can cause a decrease in sexual desire or ability, including ED, but it doesn’t happen often. One trusted source says that about 1 out of 100 people taking lisinopril might get ED. If ED does happen, it usually gets better on its own after the first few weeks.
In a study that compared lisinopril with another blood pressure medicine called atenolol, both groups had less sexual activity at first. But the people taking lisinopril returned to normal over time, while those on atenolol didn’t. Only 3% of people on lisinopril had sexual problems in that study, compared to 17% on atenolol. These findings are important when weighing treatment options for ED, especially for those comparing outcomes from medications versus devices. Understanding what is better for ED: pills or pumps? can help guide patients toward choices that best suit their health profile and response to medications like lisinopril.
How Lisinopril Helps With Blood Flow to the Penis?
The main reason lisinopril can help with ED is because it lowers high blood pressure. When blood pressure is under control, there’s less damage to the small blood vessels in the body, including those in the penis. This helps improve blood flow, which is necessary for an erection.
Lisinopril works by lowering a chemical in the body that causes blood vessels to tighten. It also boosts another chemical that helps blood vessels relax. Together, these changes improve blood flow throughout the body.
That said, in rare cases, lisinopril might lower blood pressure too much. If that happens, the blood might not reach the penis properly, and ED could occur. That’s why doctors keep an eye on blood pressure when someone first starts the medicine or changes doses. Some studies also looked at whether lisinopril affects testosterone (a hormone linked to sexual function), but the results are mixed, and there’s no clear proof it causes major changes. For men already managing ED with medication, it’s also important to consider how multiple treatments interact, such as in cases where individuals explore whether it’s safe to combine drugs like Cialis and Viagra alongside other prescriptions like lisinopril.
What Studies Say?
Different studies from Sexual Function in Hypertensive Males Treated with Lisinopril or Atenolol have looked at whether lisinopril affects sexual health. One study of 90 men with high blood pressure showed that lisinopril didn’t hurt their sex lives long-term. Another study with over 400 patients found no big difference between lisinopril and other blood pressure drugs.
Research also says other medications, like valsartan, might work even better for sex drive. But that doesn’t mean lisinopril causes ED, it just means other options might have extra benefits.
One interesting point is that when people are directly asked in surveys, many more report sexual problems than when doctors rely on patients to bring it up. For example, a review showed that only about 25% of men said they had problems on their own, but over 66% said yes when asked through a questionnaire. In fact, the rate of sexual side effects with ACE inhibitors like lisinopril may be as high as 77.8% when asked in detail.
This shows that sexual side effects are often missed in regular doctor visits. Some patients might feel too embarrassed to talk about it, and some doctors may not ask. This means sexual health issues may be more common than we think.
For doctors, it’s important to ask about sexual health in a kind and open way, using tools like surveys that help patients feel comfortable. When doctors do this, patients are more likely to keep taking their medicine, feel better overall, and trust their healthcare provider more. It also helps keep track of possible side effects more accurately, which is important for improving care in the future.

How Lisinopril Compares to Other ACE Inhibitors?
Lisinopril is part of a group of medicines called ACE inhibitors, which are used to lower high blood pressure. These types of medicines usually don’t cause erectile dysfunction (ED), and some even help improve blood flow. Other ACE inhibitors you might hear about include benazepril (Lotensin), enalapril (Vasotec), and fosinopril (Monopril).
How Other Blood Pressure Medicines Affect ED?
Doctors don’t just pick a blood pressure medicine based on how well it lowers pressure. They also consider how it affects things like energy, mood, and sexual health. Some types of blood pressure meds are more likely to cause ED than others. Here’s how they compare:
- Angiotensin II Receptor Blockers (ARBs): These medicines, like valsartan (Diovan) and losartan (Cozaar), are usually good for sexual health. They work by relaxing blood vessels, helping blood flow better, including to the penis. Some studies show that ARBs may be even better than ACE inhibitors for maintaining sexual desire. In one review, only about 30% of people taking ARBs had serious sexual problems, compared to nearly 78% of ACE inhibitors.
- Beta-blockers: These medicines are often linked to ED. They can lower interest in sex and make it harder for the penis to relax. Examples include bisoprolol, atenolol, metoprolol, and carvedilol. In one study, 17% of men taking atenolol had sexual issues, but only 3% did on lisinopril. A newer beta-blocker, nebivolol, might cause fewer problems. On average, around 44% of people on beta-blockers had moderate to severe sexual issues.
- Diuretics (Water Pills): These drugs, like hydrochlorothiazide, chlorthalidone, and furosemide, can also cause ED, especially at high doses. People on these medicines often report less interest in sex and trouble ejaculating. About 43% of patients using diuretics had serious sexual side effects.
- Calcium Channel Blockers (CCBs): Medicines like amlodipine and diltiazem usually don’t affect sexual health much. They relax blood vessels to help lower pressure. In studies, about 40% of people on CCBs had serious sexual side effects, one of the lowest rates for blood pressure drugs.
- Alpha-blockers: Drugs like doxazosin (Cardura) are less likely to cause ED and may even help improve erections. These medicines are not used just to treat ED, but they can be helpful when someone has both high blood pressure and erection issues.
- Vasodilators: Some drugs, like alprostadil, are made to treat ED directly by boosting blood flow to the penis. But others, like nitroglycerin, should never be taken with ED pills like Viagra or Cialis because they can cause dangerous drops in blood pressure.
- PDE-5 Inhibitors: These are ED medications like sildenafil (Viagra) and tadalafil (Cialis). They help increase blood flow to the penis. It’s usually safe to take these with lisinopril, but because both lower blood pressure, doctors need to know if you’re taking both. Feeling dizzy or lightheaded could mean your blood pressure is too low, and you should call your doctor right away.
Why Does This Comparison Matters?
Choosing the right blood pressure medicine can make a big difference in how someone feels and lives their daily life. If a person is worried about ED or already has it, doctors may choose an ACE inhibitor like lisinopril or an ARB instead of a beta-blocker or water pill. The goal is to keep blood pressure under control while also protecting a person’s quality of life. It’s also important that patients and doctors talk openly about side effects, so they can choose a plan that works best for both health and well-being.
