In an interview for Richard Herring's Leicester Square Theatre Podcast, Fry said: "I took a huge number of pills and a huge [amount] of vodka."
The actor revealed his producer found him in an "unconscious state".
Fry, who has bipolar disorder, has discussed his struggle with mental health issues in the past.
During the recording with Herring, in front of a live audience at the central London theatre, Fry said it was the first time he had said in public that he is "not always happy".
"I am the victim of my own moods, more than most people are perhaps, in as much as I have a condition which requires me to take medication so that I don't get either too hyper or too depressed to the point of suicide."
