Could cialis go over the counter? new study tests safe access without a prescription
NCT ID NCT06805513
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This study is testing whether men can safely use tadalafil 5 mg (Cialis) for erectile dysfunction without a prescription. Participants will use a digital health survey to check if the drug is right for them before buying it. The goal is to see if people follow dosing instructions and avoid using the drug when they have certain health conditions. If successful, this could lead to Cialis being sold over the counter.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tadalafil 5 mg (Cialis)
- What this could lead to
- If successful, this could make Cialis available over the counter, giving men easier access to treatment for erectile dysfunction without needing a doctor's visit.
- What could go wrong
- This is a real-world use study, not a test of effectiveness. Some men may still misuse the drug or ignore safety warnings, and the digital tool may not catch all risks.
