Treatment comparison
P-Shot vs Viagra for Erectile Dysfunction
Quick answer
Viagra (sildenafil) is a PDE5 inhibitor with established evidence and guideline support as first-line ED therapy for many men. PRP is an experimental injected treatment with inconsistent evidence. A P-Shot should not be presented as a proven replacement for Viagra.
Key fact: PDE5 inhibitors are guideline-supported first-line therapy for many men with erectile dysfunction, unless contraindicated. (European Association of Urology, 2026; page updated )

Key takeaways
- PDE5 inhibitors such as sildenafil (Viagra) are first-line in EAU guidance for many men; PRP evidence is insufficient for a clinical recommendation.
- Sildenafil has known dosing, contraindications and interactions; PRP protocols are not standardised.
- Sildenafil must not be combined with nitrates or nitric-oxide donors.
How they differ
- Sildenafil enhances the nitric-oxide pathway during sexual stimulation; it does not create an automatic erection.
- PRP is injected into penile tissue with the proposed aim of influencing biological repair pathways, but clinical benefit is not established.
- Sildenafil has known dosing, contraindications and drug interactions. PRP protocols are not standardised.
- Sildenafil must not be combined with nitrates or nitric-oxide donors because of dangerous blood-pressure effects.
If tablets seem not to work
A clinician should first check the likely ED cause, dose, timing, sexual stimulation, meal effects, medication authenticity and contraindications. Apparent non-response can sometimes reflect incorrect use or an untreated contributor rather than failure of the drug class.
A fair decision framework
Compare expected benefit, evidence quality, side effects, convenience, cost and alternatives. If PRP is considered, it should be framed as experimental and not as a permanent or root-cause cure.

Frequently asked questions
Is the P-Shot better than Viagra?
No evidence shows that. Viagra (sildenafil) has established evidence and guideline support as first-line therapy for many men, while PRP is experimental with inconsistent evidence.
What if Viagra does not seem to work?
A clinician should check the likely cause, dose, timing, sexual stimulation, meal effects, medication authenticity and contraindications, because apparent non-response can reflect incorrect use or an untreated contributor.
Can I take Viagra with nitrates?
No. Sildenafil must not be combined with nitrates or nitric-oxide donors because of dangerous blood-pressure effects.
