Before anything else: never stop or change a prescribed medication because you suspect it’s causing ED. Some medications, particularly for blood pressure, carry real risks if stopped abruptly. Raise it with the prescribing doctor, there’s very often an alternative that doesn’t carry the same side effect.
Medications that cause erectile dysfunction are more common than most men realise, an estimated one in four cases of ED has a medication contributing to it, which makes this one of the more overlooked causes simply because it hides in plain sight, in a pillbox most men don’t think to question. Here are four essential facts worth knowing.
1. Blood Pressure Medications Carry the Strongest Link
Diuretics (water tablets) and beta-blockers carry the strongest links to ED among blood pressure medications. Alpha-blockers and ACE inhibitors/ARBs are considerably less likely to cause it, and some evidence suggests certain blood pressure medications may even help erectile function by improving vascular health. According to WebMD, this matters because untreated high blood pressure itself causes ED, the goal isn’t avoiding treatment, it’s finding the right medication for you.
2. Antidepressants, Particularly SSRIs, Are a Recognised Cause
SSRIs (like fluoxetine and sertraline) are the antidepressant class most commonly linked to sexual side effects, working by affecting the same brain chemistry involved in arousal signalling. Not all antidepressants carry the same risk, and untreated depression itself is strongly linked to ED, so this is very much a conversation for a doctor to navigate, not a reason to stop treatment unsupervised.
3. Antihistamines and Several Other Categories Are Also Recognised
Some older, sedating antihistamines can contribute to ED, though this effect is generally milder than with blood pressure or antidepressant medications. Long-term opioid use can lower testosterone. Certain prostate medications (5-alpha-reductase inhibitors, used for enlarged prostate or hair loss) list it as a recognised side effect. Some Parkinson’s medications and certain hormone therapies used in prostate cancer treatment are also associated with it, if you’re on any of these, it’s worth mentioning specifically at your consultation.
4. Most Men Who Experience This Handle It the Wrong Way
Research on blood pressure medication specifically found that around 70% of men who experience side effects simply stop taking it, often without telling their doctor. That’s the risky pattern this article exists to head off. Stopping certain medications abruptly, especially for blood pressure, can carry real health risks well beyond erectile function.
What You Can Do Instead
List everything you’re currently taking, including over-the-counter medication, before your consultation. Note when your ED started in relation to when you started any new medication. Raise it with your prescribing doctor rather than stopping or reducing the dose yourself. Ask specifically whether an alternative with a lower ED risk exists for your condition. Keep treating the underlying condition as the priority, untreated, most of these also independently worsen ED.

Whatever your answers, a proper review of your medications with your doctor, alongside a naturopathic consultation, gives you the clearest picture.
Frequently Asked Questions
Should I just stop the medication I think is causing it?
No, please don’t, especially not without talking to your prescriber first. Some medications, particularly for blood pressure, carry real risks if stopped suddenly, and untreated conditions often cause more ED risk than the medication itself.
How do I know if it’s the medication or something else?
Timing is the biggest clue, ED that starts or clearly worsens shortly after beginning a new medication is worth discussing specifically. But other causes can coincide too, which is why a proper assessment matters more than guessing.
Can my doctor just switch me to a different medication?
Often, yes, many conditions have several treatment options with different side effect profiles. It’s a reasonable, common request to make.
Are natural supplements a safe way to counteract medication side effects?
Not automatically, some supplements interact with prescription medications. Always mention what you’re taking, including natural treatment, to whoever manages your prescriptions.
Is over-the-counter medication worth mentioning too?
Yes. Some antihistamines and other over-the-counter products are on the list of medications linked to ED, and they’re easy to overlook when listing what you take.
If it is the medication, will stopping it definitely fix the ED?
Often it helps, but not always completely, particularly if other contributing factors are also present. It’s usually one part of a fuller assessment rather than a guaranteed single fix.

Never stop or change a prescribed medication without speaking to the prescribing healthcare professional first, this is especially important for blood pressure and psychiatric medications, where abrupt discontinuation can carry real risks. This practice does not prescribe or adjust medication; where medication appears to be contributing to ED, the appropriate step is a conversation with the prescriber.
