Based on NIH | Does metoprolol increase the risk of sexual side effects like erectile dysfunction or reduced libido, and how common are these problems compared with other beta blockers?

Metoprolol can be associated with sexual side effects such as erectile dysfunction (ED) and reduced libido, but the risk appears to be modest and may be lower than with some older, non‑selective beta blockers. ^[1] In practical terms, sexual problems are reported with many blood pressure medicines, and beta blockers as a class especially older agents like propranolol have been more often linked to sexual side effects than some newer, more selective options. ^[2] That said, not everyone experiences these issues, and factors like underlying cardiovascular disease and expectation/anxiety can also play a role. ^[3]

What the evidence shows

• Official prescribing and clinical references list erectile dysfunction, decreased sexual interest, and reduced sexual performance as possible adverse effects of metoprolol. ^[1] Similar sexual side effects are listed for other beta blockers (for example, betaxolol) and are recognized as a class effect. ^[4]
• Authoritative patient guidance notes that beta blockers, particularly older ones such as propranolol, are “often linked” with sexual problems compared with some other antihypertensive classes. ^[2]
• A controlled study comparing several beta blockers (atenolol, metoprolol, pindolol, propranolol) found hormonal changes across agents, with non‑selective drugs (pindolol, propranolol) showing greater testosterone reductions than selective agents like metoprolol; clinical erectile function results were inconclusive in the short term. ^[5]
• In newly diagnosed hypertensive men started on metoprolol, reported ED varied widely depending on how much they were told about this potential side effect (32% when fully warned vs 8% when not told), suggesting a strong nocebo/expectation effect rather than a large direct pharmacologic effect. ^[3]

How common is ED with metoprolol?

Exact, uniform percentages are hard to pin down because studies use different designs, durations, and patient populations, and expectations can influence reporting. ^[3] Still, metoprolol is recognized to possibly cause decreased libido and ED, but its risk appears comparable to other cardioselective beta blockers and likely lower than older, non‑selective agents like propranolol. ^{[1] [5]} As a broader context, beta blockers as a group are flagged more often for sexual side effects than some other antihypertensive classes, although not everyone is affected. ^[2]

Comparison within beta blockers

• Non‑selective beta blockers (e.g., propranolol) have historically been more often associated with sexual dysfunction. ^{[2] [5]}
• Cardioselective beta blockers (e.g., metoprolol, atenolol) still can cause ED or reduced libido, but the signal appears smaller and more variable, with expectation and underlying cardiovascular status contributing to reported rates. ^{[1] [5] [3]}
• Product labeling across beta blockers commonly includes ED, reduced libido, or “impotence” among potential adverse effects, reflecting a class tendency rather than a metoprolol‑only issue. ^[4]

Practical takeaways

• If you notice new or worsening sexual symptoms after starting metoprolol, it could be related, but other contributors such as high blood pressure itself, vascular health, stress, anxiety, sleep issues, alcohol, and other medications often play a role. ^{[2] [3]}
• Adjusting the dose, switching to a different beta blocker or another antihypertensive class, or addressing modifiable factors may help, guided by your clinician. ^[2]
• For individuals who develop ED while on metoprolol and need treatment, phosphodiesterase‑5 inhibitors (like tadalafil) can generally be used cautiously; interactions with metoprolol have shown only small average blood pressure drops (about 5/3 mmHg with tadalafil 10 mg), but monitoring for dizziness or low blood pressure is sensible. ^{[6] [7]}

Quick comparison table

Aspect	Metoprolol (cardioselective)	Older non‑selective beta blockers (e.g., propranolol)	Class note
Listed sexual side effects (ED, reduced libido)	Yes, included in official information. [1]	Yes; historically more often linked to sexual problems. [2]	Sexual dysfunction is a recognized class effect across beta blockers. [4]
Relative signal for hormonal changes in short‑term studies	Present but smaller than non‑selective agents. [5]	Greater reductions in testosterone noted vs selective agents. [5]	Short‑term clinical ED findings are mixed/inconclusive. [5]
Influence of expectation (nocebo) on reported ED	Large effect shown: 32% vs 8% depending on information given. [3]	Not specifically tested in that study, but expectation likely relevant across agents. [3]	Counseling and balanced information may reduce nocebo‑driven symptoms. [3]

Bottom line

• Metoprolol can contribute to ED or reduced libido, but the overall risk appears modest and possibly lower than with older, non‑selective beta blockers. ^{[1] [2] [5]}
• Reported “how common” can vary widely, and expectation and underlying heart/vascular health significantly affect symptoms. ^[3]
• If sexual side effects occur, there are reasonable strategies: dose review, switching medications, lifestyle optimization, and cautiously using ED therapies when appropriate. ^{[2] [6] [7]}
