The version of the Jupiter, Florida, Police Department report made public Friday after a request by the Golf Channel contained material redacted from the version released to media last week.
A breathalyzer test showed no alcohol in his system, and the 14-time major golf champion has said an "unexpected reaction to prescribed medications" led to the incident.
Xanax can be prescribed to treat anxiety and depression as well as insomnia.
In the report originally released by authorities, Xanax was not among the drugs listed on a line for "medical conditions" which did include the pain reliever Vicodin and the anti-inflammatory Vioxx -- although Woods indicated he hadn't used Vioxx for a year.
Woods announced in May that he had undergone a fourth back surgery that would keep him off the course for the rest of the 2017 season.
He attempted a comeback after more than a year away from the game late in 2016, but played in just three tournaments.
He is scheduled to be arraigned in Palm Beach County Court on July 5.
