Never stop, pause, reduce, or change a prescribed medicine because of anything on this page. Some of the medicines listed here are dangerous to stop suddenly, and the condition being treated does not pause while you experiment. Everything here exists to make your next conversation with a prescriber more specific — not to replace it.
Sometimes reportedHeart and blood-pressure medicines
Beta-blockers and sexual side effects
Beta-blockers are the blood-pressure medicine most often blamed for erection difficulty, but trials where people did not know which drug they were taking show much smaller effects than trials where they did — expectation carries a lot of the reported burden. Older drugs in the class appear more implicated than newer ones such as nebivolol. Fatigue is a genuine and common effect and gets in the way in its own right.
What the rating means: Sexual effects turn up in the reporting for this class without being the typical experience. Worth knowing about, not worth expecting.
What is reported
Editorial categories, not percentages. Published rates vary enormously depending on study design and on whether anyone thought to ask the question.
Erections that are slower, softer, or do not hold. Because this depends on blood vessels and nerves, it can also be an early signal of something cardiovascular — which is why it is worth a clinical conversation rather than only a product.
Wanting sex less often, or losing the spontaneous interest that used to arrive on its own. This is the effect people most often assume is psychological and most often is not only psychological.
Timing and reversibility
Usually noticed in the first weeks. Beta-blockers should never be stopped abruptly — sudden withdrawal can cause a rebound in heart rate and blood pressure that is dangerous for anyone with heart disease.
Each of these has its own sexual effects, separate from the medicine’s. Working out which half you are dealing with is usually the whole question.
DiabetesDamages the small blood vessels and nerves that arousal depends on.
Thyroid conditionsOne of the most testable and most missed causes of low desire and fatigue.
High blood pressureDamages the vessels arousal depends on — before any treatment does.
Heart diseaseFear of the effort is usually a bigger obstacle than the effort.
Anxiety disordersArousal and anxiety compete for the same nervous system.
What to ask the person who prescribed it
Is the drug I am on one of the ones more associated with this?
Is my blood pressure controlled well enough that a review is reasonable?
Should the erection difficulty itself be looked at as a cardiovascular sign?
Things that help without touching the prescription
Erection difficulty can be an early cardiovascular signal in its own right, so treat it as a reason to have the heart conversation rather than a reason to avoid it.
Care signal
New erection difficulty in someone on heart or blood-pressure medicines deserves a cardiovascular assessment, not only a prescription review — the blood vessels involved are the same ones.

Which sexual side effects are most reported with beta-blockers?
The effects reported most often are fatigue or sedation getting in the way. Reported does not mean guaranteed — plenty of people take these medicines with no change at all, and published rates vary widely depending on whether anyone asked the question.
How soon would beta-blockers cause a change, and does it reverse?
Usually noticed in the first weeks. Beta-blockers should never be stopped abruptly — sudden withdrawal can cause a rebound in heart rate and blood pressure that is dangerous for anyone with heart disease.
What should I do if I notice this while taking beta-blockers?
No. Never stop, pause, or reduce a prescribed medicine on your own because of a side effect — several medicines on this site are dangerous to stop suddenly, and the condition being treated does not pause while you experiment. Bring the observation to the person who prescribed it; a dose review, a different preparation, or a different approach may all be options, and only they can weigh them against what the medicine is doing for you.
What should I ask about beta-blockers at my appointment?
A specific question gets a better answer than a general one. For this class: Is the drug I am on one of the ones more associated with this? Is my blood pressure controlled well enough that a review is reasonable? Should the erection difficulty itself be looked at as a cardiovascular sign?
When is this worth an appointment rather than a wait-and-see?
New erection difficulty in someone on heart or blood-pressure medicines deserves a cardiovascular assessment, not only a prescription review — the blood vessels involved are the same ones.
Educational information about categories of medicine only — not medical advice, not a diagnosis, and not a statement about your prescription. It does not cover doses, interactions between medicines, or alternatives, and it cannot know what else is going on with your health. Sexual symptoms often have more than one cause at once. Pain, bleeding, or a symptom that is new and unexplained always deserves assessment.
