Miley Cyrus was forced to cancel a couple of concert dates in Missouri this week due to a severe allergic reaction to antibiotics. Her camp has since shed more light on what exactly is bothering her.
A rep for Miley says in a statement the singer obtained a prescription for an antibiotic known as cephalexin to treat a sinus infection that was diagnosed last week. She subsequently suffered an allergic reaction to the drug. Cephalexin is also sold under the brand name Keflex.
The rep says such a reaction can last from five to 27 days. The statement adds, "She will remain hospitalized and is under a doctor's care until we see some improvement in her condition and is asking for your compassion and privacy at this time."
Miley was hospitalized in Kansas City on Tuesday. So far, she's cancelled dates in Kansas City and in St. Louis.
The allergic reaction occurred one week after Miley cancelled a concert in Charlotte, North Carolina, due to a bout with the flu.
