Does Lisinopril Lower Your Sex Drive?

Lisinopril can cause a temporary dip in sexual activity when you first start taking it, but the effect tends to fade with continued use. In a crossover trial comparing lisinopril to the beta-blocker atenolol, only about 3% of men on lisinopril reported lasting sexual dysfunction symptoms, compared to 17% on atenolol.¹ Among blood pressure medications, ACE inhibitors like lisinopril sit squarely in the “better tolerated” camp when it comes to sexual side effects, though the picture is more layered than a simple yes or no.

The First Month Is the Rough Patch

The most detailed look at lisinopril’s effect on sexual function comes from a study that tracked sexual activity in men with high blood pressure who were randomly assigned to either lisinopril or atenolol, with a placebo period for comparison. During the first month on lisinopril, the average number of sexual intercourse episodes per month dropped from about 7 to 5, a statistically meaningful decline compared to placebo. That sounds concerning on its own, but what happened next matters more: with ongoing treatment, sexual activity bounced back to roughly 7.7 episodes per month, which was no longer different from placebo.¹

Atenolol, by contrast, drove sexual activity down in the first month and kept it there. Men on atenolol averaged about 4.2 episodes per month even after continued treatment, and the difference between the two drugs was highly significant. The researchers described lisinopril’s effect as a “temporary decline” and atenolol’s as a “chronic worsening.” If you have just started lisinopril and noticed a change in your sex drive or performance in the first few weeks, the evidence suggests patience is warranted before blaming the drug long-term.

How Lisinopril Compares to Other Blood Pressure Medications

Blood pressure drugs are not all alike when it comes to sexual side effects. Older classes of medication, particularly beta-blockers and some diuretics, have the worst reputation. Newer classes, including ACE inhibitors like lisinopril, calcium channel blockers, and angiotensin receptor blockers (ARBs), tend to fare much better. A review of the evidence found that ACE inhibitors and ARBs have “neutral or even positive” effects on erectile function, while beta-blockers remain the class most often linked to erectile difficulties.² A proposed management algorithm for clinicians dealing with drug-related sexual dysfunction similarly categorized ACE inhibitors as having a neutral effect, placing them in the same favorable tier as calcium channel blockers.³

A large network meta-analysis added a more cautious note. When researchers pooled data across studies and compared all the major drug classes head-to-head, no single class showed a statistically significant difference from placebo in terms of erectile function.⁴ That doesn’t mean beta-blockers are harmless. It means the differences between drug classes, while real in some head-to-head studies, may be smaller across the board than many patients and doctors assume. Still, when there is a choice to be made, lisinopril and similar ACE inhibitors are consistently placed in the safer column.

High Blood Pressure Itself Is the Bigger Problem

One of the most important and most overlooked aspects of this question is that high blood pressure, all by itself, damages sexual function. It does this by harming blood vessels over time, and the blood supply to the genitals is no exception. A review of the relationship between aging, hypertension, and sexual problems found that vascular disease tied to high blood pressure, diabetes, and atherosclerosis is likely the primary contributor to sexual dysfunction in these populations.⁵ Researchers have proposed that erectile dysfunction may simply be another manifestation of the same atherosclerotic vascular disease that causes heart attacks and strokes.⁶

This creates a frustrating paradox. You start taking a blood pressure medication, and around the same time you notice changes in your sex life. It’s natural to blame the new pill. But the underlying condition you’re treating was already chipping away at the same blood vessels that sustain sexual arousal. Stopping the medication to “fix” the problem can leave you worse off, because uncontrolled blood pressure accelerates the very vascular damage that causes sexual dysfunction in the first place. If you notice a change after starting lisinopril, it’s worth having a frank conversation with your doctor, but stopping treatment on your own is one of the worst things you can do for both your cardiovascular health and your long-term sexual function.

What Lisinopril Does to Hormones

Beyond the vascular picture, there’s a hormonal angle that gets less attention. A small study of male patients with hypertension found that lisinopril lowered free testosterone levels by a meaningful amount, from an average of about 13.8 pg/mL to about 9.9 pg/mL, while total testosterone and estradiol remained unchanged.⁷ Free testosterone is the fraction that’s biologically active, and a drop like that could plausibly affect libido in some men.

A separate, larger study looked at ACE inhibitors as a class (not lisinopril specifically) and found that older men using ACE inhibitors had lower levels of DHEA, a precursor hormone the body converts into both testosterone and estrogen, compared to non-users with similar blood pressure histories.⁸ Testosterone itself wasn’t significantly changed in that study, which creates some ambiguity. The honest answer here is that these hormonal shifts have been observed, but the research is preliminary and small. Whether they translate into meaningful libido changes for most people taking lisinopril is not yet clear.

The practical takeaway: if you’ve been on lisinopril for several months and your sex drive feels genuinely different, it may be worth asking your doctor about checking your hormone levels, particularly free testosterone. A simple blood test can rule this in or out as a contributor.

The Power of Expectation

Here’s something that might surprise you: just being told that a medication can cause sexual side effects makes you more likely to experience them. This is the nocebo effect, which is essentially a placebo effect in reverse. Research on nocebo responses has shown that disclosing potential side effects can itself contribute to producing those adverse effects, and the way information is presented to patients influences how strongly the effect takes hold.⁹

This is directly relevant to lisinopril and sexual function. Many package inserts, pharmacy handouts, and internet searches will tell you that “ACE inhibitors can cause sexual dysfunction.” Reading that warning primes your brain to monitor for the problem and interpret normal fluctuations in desire or performance as drug side effects. Clinical trials have shown this consistently: groups of patients told a drug may cause sexual issues report much higher rates of those issues than groups taking the same drug who are not told, even when the pill is a placebo. That doesn’t mean your experience isn’t real if you notice a change. It means the brain’s role in sexual function is enormous, and anxiety about a side effect can become a self-fulfilling prophecy.

What About Women?

Almost all the lisinopril-specific sexual function research was done in men, which is a common gap across cardiology research. The broader question of how blood pressure drugs affect women’s sexual function is genuinely understudied. A review of the available evidence found that female sexual dysfunction in hypertension is poorly understood and that the impact of antihypertensive agents on women has not been clearly defined.¹⁰ The one consistent finding is that beta-blockers have the strongest evidence of harming female sexual function, while ARBs appear relatively beneficial. ACE inhibitors weren’t singled out either way for women in that review.

The lisinopril-specific hormone study mentioned earlier did note an effect in women: lisinopril increased sex hormone binding globulin (SHBG), a protein that essentially ties up hormones and makes them less available.⁷ Elevated SHBG has been linked to lower sexual desire in women in other contexts, but whether the amount of increase caused by lisinopril is large enough to matter hasn’t been studied. If you’re a woman taking lisinopril and noticing changes in desire or arousal, you’re navigating a genuine blind spot in the medical literature. Your concern is valid, but the data to guide your doctor is thin.

Using Erectile Dysfunction Medications with Lisinopril

A common worry for men who develop erectile problems on any blood pressure drug is whether it’s safe to take medications like sildenafil (Viagra) or similar drugs at the same time. The evidence here is reassuring. A large safety analysis covering nearly 4,000 men across 18 controlled studies found that the rate of side effects for men taking sildenafil alongside antihypertensive medication, including ACE inhibitors, was similar to the rate in men taking sildenafil alone. The incidence of potentially blood-pressure-related events like dizziness, low blood pressure, or fainting was not increased, even in men taking multiple blood pressure drugs from different classes.¹¹

There is one important exception the study didn’t cover: nitrate medications, like nitroglycerin, used for chest pain. The combination of a PDE5 inhibitor (the class that includes sildenafil) with nitrates can cause a dangerous drop in blood pressure and is contraindicated. But lisinopril is not a nitrate, and combining it with sildenafil doesn’t carry that risk. If erectile issues persist despite continued lisinopril use, asking your doctor about adding an erectile dysfunction medication is a medically sound option for most men.

When to Talk to Your Doctor About Switching

The research consistently places ACE inhibitors near the top of the list for sexual tolerability among blood pressure drugs. But “near the top” isn’t the same as “zero risk for everyone.” If you’ve been on lisinopril for more than a couple months, the initial adjustment dip should have resolved, and any persistent sexual dysfunction deserves a real evaluation. Your doctor might consider a few angles:

Other medications: If you’re also taking a beta-blocker, a diuretic, or an antidepressant, those drugs are far more likely culprits than lisinopril.
Underlying vascular disease: Erectile dysfunction can be an early warning sign of cardiovascular disease independent of any medication. Reporting it honestly could lead to important diagnostic workups.
Switching within the class: ARBs (like losartan or valsartan) are closely related to ACE inhibitors and have preliminary evidence suggesting they may mildly benefit sexual function. Switching from an ACE inhibitor to an ARB is common for other reasons (like a persistent cough) and might be worth trying if sexual side effects are a concern.
Dose adjustment: Though the available lisinopril research didn’t isolate a clear dose-response relationship with sexual dysfunction, lower doses produce fewer side effects in general.

The worst outcome is skipping your medication entirely. Blood pressure drugs rank among the medications with the highest rates of non-adherence, and sexual side effects are one of the most common reasons people stop taking them. Untreated high blood pressure will, over years, do far more damage to your sexual function than lisinopril ever could.

The Difference Between Libido and Erectile Function

These two things get tangled together in conversation, but they are distinct. Libido refers to desire, the psychological drive toward sexual activity. Erectile function refers to the physical ability to achieve and maintain an erection. Most research on blood pressure drugs and sexual function focuses on erectile function because it’s easier to measure, but what people often mean when they say a drug “killed their sex drive” is actually a drop in desire.

Lisinopril’s hormonal effects, specifically the drop in free testosterone, could plausibly affect libido more than the physical mechanics of erection. Meanwhile, the vascular effects of high blood pressure itself tend to affect erectile function more directly, because adequate blood flow is the mechanical basis of an erection. This distinction matters when troubleshooting: if your desire is fine but erections are unreliable, the issue might be vascular and worth exploring with your cardiologist. If desire itself has tanked, hormonal factors or the nocebo effect become more relevant to investigate. Separating the two gives both you and your doctor a better starting point for figuring out what’s actually going on.
