The ultimatum follows rumours that plans to release a new record this year have been shelved after the singer pulled out of a recording session at the last moment.
Record execs have been forced to remind Winehouse "of her responsibilities".
A source revealed: "Unless she is clean she will not be allowed to release another album.
"She took notice when Lucian [Grainge, Universal Chairman and CEO] talked to her earlier in the year and agreed to go to rehab. But she didn’t take it seriously enough.
"They would never release her from her deal, they would just not put an album out."
Winehouse's last album, 2006's Back to Black, is currently at number seven in the UK album chart.
