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 cause no withdrawal syndrome. You can stop at any time without tapering. What happens to your erectile function after stopping depends entirely on why you were taking the medication.
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 are not physically addictive and do not cause physical dependence. There is no withdrawal syndrome, no rebound phenomenon, and no requirement 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 required; simply discontinue. Tadalafil has a half-life of approximately 17.5 hours and takes 3–5 days to clear from the body after stopping daily dosing
Reasons Men Consider Stopping
Side effects
Headache, flushing, nasal congestion, or back pain (more common with tadalafil) may be unpleasant enough to consider stopping. Before discontinuing, discuss with your prescriber: reducing the dose often significantly reduces side effects while maintaining efficacy, and switching between PDE5 inhibitors can avoid specific side effects.
ED has resolved
For men who started ED medication for a predominantly psychological reason — performance anxiety, stress, relationship tension — and who have since addressed the underlying issue, the ED may genuinely no longer be present. A trial without medication in a relaxed, low-pressure situation is entirely appropriate.
Lifestyle changes
Significant weight loss, improved cardiovascular fitness, better-controlled diabetes, or stopping smoking can address underlying physical causes. If lifestyle has improved substantially, a trial without medication is reasonable.
Relationship or personal reasons
A relationship ending, periods of celibacy, or a personal decision to pause sexual activity are all valid reasons to stop. Simply stop taking the medication. If you need it again, a prescriber review will be straightforward.
What Happens When You Stop ED Medication
When you stop a PDE5 inhibitor, the direct pharmacological effect ends 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 has not 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 (dose needing to increase 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 with physical causes of ED that are not reversible. Regular prescriber review is recommended — not for safety concerns, but to ensure the dose remains appropriate as your health status changes over time.
If ED Returns After Stopping
If ED returns after you stop, this is not a failure — it simply means the underlying cause is still present. Options:
- Resume the same medication at the same dose
- Reassess with a prescriber if your health has changed since your last consultation
- Consider addressing underlying causes more actively — lifestyle changes, psychological support, 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 are not 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.
