The University of South Florida and Tampa General Hospital have joined onto a nationwide study to look at existing medications as possible treatments for COVID-19 infections. 

According to the ACTIV-6 study website, the Duke Clinical Research Institute is coordinating the study along with Vanderbilt University Medical Center.

To be eligible for the study, an individual must be at least 30 years old, have tested positive for COVID-19 within the past 10 days and have at least two symptoms, which include fatigue, difficulty breathing, fever, couch, and nausea, among others. 

ACTIV-6 is a nationwide double-blind study that is expected to eventually have nearly 15,000 participants. People can participate from any part of the United States via the study's website or by calling 833-385-1880.

Medications currently being studies include fluvoxamine, a selective serotonin reuptake inhibitor; fluticasone, an inhaled steroid; and ivermectin, which is used to treat parasitic infections.

USF's Dr. Jason Wilson said participants will not have to leave their homes to be a part of the study.

"If you decide to take part in our study, our team reaches out to you. We have a conversation and get you medicine delivered the next day to your house in the mail," he said. "So, really, all the encounters will happen by phone and by mail, and you'll always have that research team available to answer your questions."
