Stopping ED Medication: What Happens and When It Makes Sense
Whether ED returns, long-term safety, when stopping is appropriate, and what to do if ED comes back.
Part of the Access Doctor Erectile Dysfunction guide.
Key fact: PDE5 inhibitors (sildenafil, tadalafil, vardenafil, avanafil) are not physically addictive and there's no withdrawal syndrome. You can stop at any time without tapering. What happens to your erectile function afterwards depends entirely on why you were taking the medication in the first place.
Resume or Change ED Treatment
If ED has returned or you want to change medication, Access Doctor’s GPhC-registered pharmacist independent prescribers can assess your situation via a confidential online consultation.
Start Consultation →Can You Just Stop Taking ED Medication?
Yes. PDE5 inhibitors aren't physically addictive and don't cause physical dependence. There's no withdrawal syndrome, no rebound effect, and no need to taper the dose before stopping.
- On-demand sildenafil or tadalafil — stopping is as simple as not taking the next tablet
- Daily tadalafil 5mg — no tapering needed; just stop. Tadalafil has a half-life of about 17.5 hours and clears from the body over 3–5 days after you stop daily dosing
Reasons Men Consider Stopping
Side effects
Headache, flushing, nasal congestion or back pain (more common with tadalafil) can be unpleasant enough to make you think about stopping. Before you do, talk to your prescriber: a lower dose often cuts side effects while keeping the benefit, and switching between PDE5 inhibitors can sidestep specific ones.
ED has resolved
If you started ED medication for a mainly psychological reason — performance anxiety, stress, relationship tension — and you've since worked through it, the ED may genuinely be gone. A trial without medication in a relaxed, low-pressure setting is entirely reasonable.
Lifestyle changes
Significant weight loss, better cardiovascular fitness, well-controlled diabetes or stopping smoking can all improve the underlying physical causes. If your lifestyle has changed substantially, a trial off medication makes sense.
Relationship or personal reasons
A relationship ending, a period of celibacy, or a personal decision to pause sexual activity are all valid reasons to stop. Simply stop taking the tablets. If you need them again later, a prescriber review is straightforward.
What Happens When You Stop ED Medication
When you stop a PDE5 inhibitor, the direct pharmacological effect wears off as the drug clears your system. What happens to erectile function after that depends on the underlying cause:
| Reason for original ED | Likely outcome after stopping |
|---|---|
| Psychological ED (anxiety, stress) that has been treated or resolved | ED may not return, or may return only mildly. Many men with resolved psychological causes stop successfully. |
| Psychological ED that hasn't been fully addressed | ED likely returns. Medication was managing the symptom, not the cause. |
| Lifestyle factors that have been addressed (weight, smoking, exercise) | May not return, or may return at lower severity. |
| Physical causes (diabetes, cardiovascular disease) that are ongoing | ED returns when medication is stopped. Long-term use is often appropriate. |
| Post-prostatectomy nerve damage | ED returns unless nerve recovery has occurred. Long-term use usually required. |
Is Long-Term Use of ED Medication Safe?
Yes. Sildenafil has been in clinical use since 1998 — nearly three decades of post-marketing safety data. There is:
- No evidence of harmful cumulative effects at prescribed doses
- No evidence of tolerance (needing a higher dose over time for the same effect)
- No organ toxicity associated with long-term use
- No physical dependence or addiction
Long-term use is entirely appropriate and commonly recommended for men whose ED has a physical cause that isn't reversible. Regular prescriber review is a good idea — not because of safety concerns, but to make sure the dose still fits as your health changes over time.
If ED Returns After Stopping
If ED comes back after you stop, it's not a failure — it just means the underlying cause is still there. Your options:
- Resume the same medication at the same dose
- Reassess with a prescriber if your health has changed since your last consultation
- Consider tackling the underlying causes more actively — lifestyle changes, psychological support, better management of diabetes or hypertension
- Consider switching from on-demand sildenafil to daily tadalafil for more convenient continuous coverage (see tadalafil vs sildenafil)

Frequently Asked Questions
Can I just stop taking sildenafil or tadalafil?
Yes. PDE5 inhibitors aren't addictive and cause no withdrawal. Stop on-demand medication by not taking the next tablet. Daily tadalafil needs no tapering — simply discontinue.
Will erectile dysfunction come back when I stop ED medication?
Depends on the cause. Psychological ED that has been addressed may not return. Physical causes (diabetes, cardiovascular disease) mean ED will return when medication stops. Long-term use is appropriate for these men.
Is it safe to take sildenafil or tadalafil long-term?
Yes. Nearly 30 years of post-marketing data shows no harmful cumulative effects, no tolerance, and no organ toxicity at prescribed doses.
Can I stop ED medication if I’ve made lifestyle changes?
Yes — a trial without medication is reasonable if lifestyle has substantially improved. Try in a relaxed, low-pressure situation and assess without expectation or pressure.
What should I do if ED returns after stopping medication?
Resume medication, reassess with a prescriber if your health has changed, and consider whether addressing underlying causes more actively might reduce future dependence.
Why might I want to stop ED medication?
Side effects (try dose reduction or switching), ED having resolved, lifestyle improvements, relationship changes, or cost and convenience.
