Charlie Sheen has admitted that he was briefly off his medications to treat HIV after trying a controversial but ultimately ineffective treatment in Mexico.  

The actor revealed while appearing on Dr. Oz Tuesday that he did travel to Mexico where he met with Dr. Samir Chachoua, who claims to know how to cure both AIDS and cancer, and went through a series of injections.  

"We did see some incredible results early on," Sheen said of the treatment. "Off the med cocktail that I was undetectable. And it stayed that way. I did an experiment I didn't have any faith in but I went along with it." 

Among the treatments wad Chachoua injecting himself with Sheen's blood, something Oz noted wasn't appropriate, but that Sheen said he found to be a mind-blowing experience. 

"Inappropriate and completely mind-blowing," he said. "I watched that happen when he felt so confident. He delivered that my blood would not be any risk to him." 

Sheen also admitted he didn't see it as a risky move at the time. 

"I didn't see it as Russian Roulette," he said. "I didn't see it as a complete dismissal of the conventional course that we had been on. I'm not recommending that anybody else do this. I'm presenting myself as some kind of a guinea pig." 

However, the beginning of the show saw a more somber Sheen as he admitted he had recently learned some devastating news that he was no longer testing as non-detectable, and that he would have to go back on the cocktail.  

"I'm a little off my game because right before I walked out here, I got some results I was disappointed about," he said. "I had been non-detectable, non-detectable and checking the blood every week and then found out the numbers are back up." 

"I'm going to take them [the medications] to take them on the flight home. What am I, an idiot?" he added.
