Joe Rogan has tested positive for COVID-19.
The podcaster, who is currently on tour, shared the news with fans on Instagram as he explained why he needs to reschedule Friday's show in Nashville.
The 54-year-old, who had previously sparked criticism for his remarks about vaccines, told fans he started feeling sick on Saturday.
"I got back from the road Saturday night feeling very weary," Rogan told his 13 million Instagram followers in a video on Wednesday, September 1.
"I had a headache, and I just felt just run down. Just to be cautious, I separated from my family, slept in a different part of the house, and throughout the night I got fevers and sweats and I knew what was going on. I got up in the morning, I got tested and it turns out I got COVID," he explained.
The UFC commentator said he immediately started "all kinds of meds," including ivermectin - a drug that is typically used to treat or prevent parasitic worms in animals.
The FDA has not approved ivermectin for use in treating or preventing COVID-19 in humans, per CNBC.
Rogan also mentioned using a monoclonal antibody treatment, Z-Pak, the steroid prednisone, NAD drip, and vitamin drip.
He explained: "We immediately threw the kitchen sink at it - all kinds of meds. Monoclonal antibodies, ivermectin, Z-pack, prednisone - everything."
"Crazy times we’re living in, but a wonderful, heartfelt thank you to modern medicine for pulling us out so quickly and easily," he added.
He went on: "Here we are on Wednesday and I feel great. I really only had one bad day, Sunday sucked. Today I feel good. I actually feel pretty f***ing good."
Rogan has not publicly said whether he is vaccinated, but he generated a storm of controversy back in April when he told listeners he didn’t believe young, healthy people needed to get the vaccine.
He has since clarified his stance on vaccines generally, saying he supports them.
"I'm not an anti-vax person," he explained on a later episode, per BBC News. "I believe they’re safe and encourage many people to take them."
