Lee Burdick, the mayor's chief of staff, said Filner began the program early because of the media firestorm, KGTV in San Diego reported. Burdick said the mayor would be back in the city but did not say if he would be back at work.
Fourteen women have accused Filner of making unwanted sexual advances to them, including propositions and groping.
Also Friday, U.S. Sen. Barbara Boxer, D-Calif., sent Filner an open letter urging him to step down. She said he should get the help he needs "as a private citizen."
Boxer said she has previously called for Filner's resignation, speaking as a senator. She said in the letter she was speaking as someone who has known Filner for years.
"But now I must say this directly to you: Bob, you must resign because you have betrayed the trust of the women you have victimized, the San Diegans you represent and the people you have worked with throughout your decades in public life," Boxer said.
