A penile implant gives a firm erection on demand, so many men understandably ask: do I still need erection tablets such as sildenafil (Viagra) or tadalafil (Cialis) afterwards? The short answer is no — the implant itself does the work of the erection. But there are a few specific situations where a PDE5 inhibitor may still add something. Here is a balanced, expert view.
Quick answer: For the erection itself, you do not need Viagra or Cialis after a penile implant — the device provides rigidity mechanically. A PDE5 inhibitor is optional and is considered only to improve fullness of the glans (head) or sensation in selected men, and only when your doctor confirms it is safe for you.
Why the implant makes erection tablets unnecessary
PDE5 inhibitors (phosphodiesterase type 5 inhibitors) work by improving blood flow into the erection chambers of the penis. After a penile implant, rigidity no longer depends on blood flow — the device provides it mechanically:
- A malleable (semi-rigid) implant keeps the penis permanently firm, ready for intercourse.
- An inflatable penile prosthesis (IPP) is inflated on demand for an erection and deflated afterwards.
So for the erection itself, tablets are not needed. This is exactly why the implant is chosen — usually after erection medicines have either stopped working or could not be tolerated. Removing the need for daily or on-demand pills is one of the main advantages of an implant.
When a PDE5 inhibitor may still help
A small number of men may still benefit from a PDE5 inhibitor for reasons unrelated to rigidity:
- Glans (head) engorgement. An implant firms the shaft but does not support the far tip — roughly the distal third of the glans is not held by the device. This can leave the head feeling softer or cooler than the shaft, a pattern sometimes called floppy glans syndrome. Because the glans still fills with natural blood flow, a PDE5 inhibitor can improve that flow and help the head feel fuller. Published studies report that adding a PDE5 inhibitor after an implant can improve glans engorgement and overall satisfaction for both the man and his partner.
- Sensation and overall experience. Some men report improved sensation or a more complete feeling of arousal.
- Selected clinical reasons. A uroandrologist may occasionally recommend a short, individualised course for specific reasons after assessment.
Benefits vs. considerations
| Potential benefits | Things to consider |
| Fuller, warmer glans (head) for men who notice a soft tip | Prescription-only medicines with possible side effects — headache, facial flushing, nasal congestion, indigestion |
| Possibly improved sensation and satisfaction for some men | Not safe with nitrate heart medicines — the combination can cause a dangerous drop in blood pressure |
| A non-surgical add-on when the implant alone leaves the glans soft | Added cost; the benefit is individual, not universal |
| They do not change the implant’s rigidity |
The expert view
For most men, a penile implant removes the need for erection tablets entirely — that is precisely why they chose it. PDE5 inhibitors after an implant are optional and individualised, considered mainly to improve glans fullness or sensation in men who want it, and only when it is medically safe. They should never be started without your doctor’s advice, especially if you have heart disease or take nitrates. The right approach is a personalised discussion with your uroandrologist about whether they would add anything for you.
Frequently Asked Questions
Do I need Viagra or Cialis after a penile implant? Not for the erection itself — the implant provides that. Some men use a PDE5 inhibitor only to improve fullness of the glans (head) or sensation, and only if their doctor confirms it is safe for them.
Will Viagra or Cialis make my implant firmer? No. These tablets do not change the implant’s rigidity. Their only possible effect is on the natural blood flow to the glans and surrounding tissue, which in some cases can add a little fullness to the head over the implant.
Can everyone take these tablets after an implant? No. PDE5 inhibitors are unsafe with nitrate heart medicines and are not suitable for everyone. Always check with your uroandrologist before taking them.
Why does the head of my penis feel soft after a penile implant? The implant supports the shaft but not the far tip of the glans, so the head can feel softer or cooler. This is sometimes called floppy glans. A PDE5 inhibitor may improve natural blood flow to the glans; other options exist too, so it is worth discussing with your surgeon.
How soon after implant surgery can I consider a PDE5 inhibitor? Only when your surgeon says healing is complete and it is appropriate for you. Timing and suitability are individual decisions made after review.
Are there side effects of taking Viagra or Cialis after an implant? Possible side effects include headache, facial flushing, a blocked or runny nose and indigestion. They must not be combined with nitrates. Your doctor will weigh the benefit against these risks for you.
