Taylor's spokesman Dick Guttman said that the 77-year-old entered the facility as a matter of routine and insisted that she was well enough to inform fans about her progress via Twitter.
Guttman confirmed that the star would return home "soon" but failed to provide details of why she had required medical attention.
In an interview with People magazine, he dismissed recent reports claiming that Taylor was in ill health as "dramatic, overstated and untrue" and added that she was "living her life" and "having dinner with friends".
Taylor has the brittle bone disease osteoporosis as a result of breaking her back five times. She underwent a hip replacement in 1995 and had surgery to remove a brain tumour in 1997.
The actress, who was appointed Dame Commander of the Order of the British Empire in 1999, has won Oscars for her roles in both Butterfield 8 and Who's Afraid of Virginia Woolf?.
