What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is studying whether detergents in products like toothpaste can make the esophagus lining leaky and cause allergic reactions. It focuses on people who might have allergic inflammation in their esophagus due to these detergents.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, you must avoid using toothpaste with SLS (a common detergent) for 2 weeks before the study.

Is the treatment generally safe for humans?

Most people exposed to liquid laundry detergent capsules have no symptoms or only minor issues, but some can experience serious problems like breathing difficulties or eye injuries. Safety measures have been put in place to reduce risks, especially for children. ^{1 2 3 4 5}
