Actual Use Trial of Tadalafil 5 mg
Investigating the Use of an Investigational Medication for Erectile Dysfunction
Study Overview
The purpose of this actual use trial (AUT) is to evaluate if participants can appropriately select and use the study product [Cialis over the counter (OTC)] using the labeling and the mandatory health survey assessment (HSA) for duration of 4-months.
Study Details
This will be an open-label 4-month AUT of tadalafil 5 mg tablet in men who are interested in an OTC treatment for erectile dysfunction. The open-label study will enroll approximately 2,250 participants who qualify for treatment based on the data they enter into the HSA of which an estimated 1000 participants will ultimately proceed to the use phase.

You may be eligible for this study if you meet the following criteria:
- Conditions: Erectile Dysfunction

Inclusion Criteria:
Participants will be included in Part II (enrolment phase) if they are:

This study investigates the use of an investigational medication for erectile dysfunction. Erectile dysfunction is when someone has trouble getting or keeping an erection. The study will look at whether participants can properly choose and use the medication by following the instructions on the label and completing a health survey. It will involve around 2,250 participants, but only about 1,000 will move on to actually using the medication.
Participants will first fill out a health survey to see if they qualify. Those who qualify will buy the investigational medication and use it as directed. The study will involve taking a 5 mg tablet of the investigational medication. Participants must record their experiences in an electronic diary, which is a digital way to keep track of how they feel and any side effects they may have.
- Who can participate: Participants must be 16 years or older and live in the US. For the use phase, participants must be male, at least 18 years old, and complete a health survey with a purchase code for the investigational medication.
- Study details: Participants will purchase the investigational medication after completing a health survey. They will take the medication and record their experiences in an electronic diary. A placebo is not used in this study.
- Study Timelines: The study will last 4 months.
