Joe Rogan announced on Instagram that he tested positive for COVID-19 and felt "run down."
The podcast host and MMA commentator said he separated from his family after he started feeling sick Saturday night.
"Throughout the night I got fevers and sweats and I knew what was going on," Rogan said.
Rogan got tested for COVID-19 the next morning, and got a positive result, he said.
He said he tried a variety of treatments including monoclonal antibodies and ivermectin.
The Food and Drug Administration (FDA) warns against using ivermectin, an antiparasitic, to treat COVID-19.
"Taking large doses of this drug is dangerous and can cause serious harm," the FDA says.
Rogan said he is now feeling good.
"Crazy times we’re living in, but a wonderful, heartfelt thank you to modern medicine for pulling us out so quickly and easily," Rogan said.
Rogan has faced criticism for his controversial remarks about COVID-19. In the past, he said young, healthy people did not need to get the COVID-19 vaccine. He also said "vaccine passports" were a step toward dictatorship.
Dr. Anthony Fauci, White House chief medical advisor, was asked on NBC's Todayabout Rogan's comments. He said young, healthy individuals do not live in a vacuum and "are propagating the outbreak" if they don't get vaccinated.
