The wicketkeeper-batter, 26, has been a key part of the England set-up since making her international debut in 2006.
She is England's third highest one-day international run-scorer and second only to Charlotte Edwards in T20 games.
In October last year, Sussex's Taylor, who took a four-month sabbatical in 2010, became the first woman to play in Australian first-grade cricket.
The England and Wales Cricket Board said Taylor could still feature in the one-day and Twenty20 series against Pakistan beginning on 20 June.
An ECB spokesperson said they were continuing to monitor the situation and that the board would "support her, keep in touch and talk with her prior to selection for the Pakistan series and the start of the Super League".
Taylor has scored 5,581 international runs in 190 appearances, claiming 114 catches and 88 stumpings, and is one of only seven women to play in 100 ODIs for England.
Last November, her Sussex team-mate Holly Colvin retired from international cricket to take up a role with the ICC in Dubai.
And last week, England captain and record run-scorer Charlotte Edwards announced her international retirement after being told coach Mark Robinson wanted to build a new team.
England's Sarah Taylor is taking an indefinite break from cricket for personal reasons.
