"Rainikanth, admitted to Sri Ramachandra Medical University on May 13 for respiratory and gastro intestinal problems for which he had undergone relevant investigations, is receiving appropriate and comprehensive treatment. His vital parameters are stable," an SRMU release said.
The 61-year-old actor is spending his time with his family members, it added.
The Enthiran star, who suffered from viral fever and exhaustion recently, was admitted to SRMU at suburban Porur days after he was discharged from another hospital where he was treated for allergic bronchitis and viral fever.
He had suffered from exhaustion on April 29, the first day of the shoot of his new period film Rana co-starring Deepika Padukone, which is being directed by K S Ravikumar. He was admitted to Isabel Hospital in Chennai and discharged the same day, only to be re-admitted on May 4 for allergic bronchitis and viral fever.
His family had last week dismissed reports that his health had deteriorated.
