Miley Cyrus is postponing her U.S. tour while she recovers from an allergic reaction to antibiotics, but will resume her performances in August.

Cyrus' representative tells The Associated Press on Friday that the singer will resume the U.S. tour Aug. 1 in Uniondale, N.Y. The new dates will include seven rescheduled shows and two additional stops.

The European leg of the tour is still scheduled to kick off May 2 in Amsterdam.

Cyrus' rep says the singer suffered from a sinus infection last week during her "Bangerz" tour and had "an extreme allergic reaction" to the antibiotic cephalexin on Tuesday. Cyrus canceled several shows this week as a result.

Existing tickets for the 21-year-old singer's U.S. tour will be honored at the new date.
