Beale, who has had a well-documented battle with alcohol, made the decision to seek professional help on Monday in a bid to resolve personal issues that have dogged him in recent times.
The 24-year-old was suspended in March after punching skipper Gareth Delve and team-mate Cooper Vuna on the team bus following a heavy loss in South Africa.
He sought counselling and was cleared to return for the Rebels a fortnight ago.
But Beale was suspended again last week after he violated an agreement with the club and Australian Rugby Union not to drink alcohol.
Beale's decision casts serious doubt over his availability for the three-Test series against the British and Irish Lions in June-July.
Coach Robbie Deans will name his initial 25-man squad on Sunday, with a further six players to be added on June 11.
The series will be staged over three consecutive Saturdays starting on June 22 in Brisbane.
Melbourne and Sydney are the venues for the second and third Tests.
Beale's Rebels and Wallabies team-mate James O'Connor confirmed he has spoken to his close friend and urged the former John Eales Medallist to put his own well being before rugby.
"Everyone wants to see him back on the field," O'Connor said on Monday.
"I have spoken to him to make sure he is all right and he is trying to stay positive.
"Number one is Kurtley's well being and looking after Kurtley and making sure he is right.
"He has got to look after his personal life first ... then rugby can come back into it."
