Miley Cyrus reportedly spent several days in the hospital because of an allergic reaction to an antibiotic drug. However, it has now been revealed that the pop star was hospitalized because she actually needed a detox program to cleanse her system of an excess of drugs she had previously consumed.

Cyrus' official statement released by her PR agency claimed that the "Adore You" singer was prescribed the antibiotic Cephalexin, which apparently reacted extremely allergic to her body, simply to treat her sinus. "This type of extreme reaction can last from five to 27 days in these types of cases," the statement read.

However, a recent report claimed, if the 21-year-old singer had really been hospitalized for an allergic reaction to Cephalexin, it would just have been a stay of maximum 24 hours rather than several days, quoting Wikipedia as source: "A period of in-hospital observation for between 2 and 24 hours is recommended for people once they have returned to normal due to concerns of biphasic anaphylaxis."

"Anyone who has ever had a medication induced allergic reaction will tell you that treatment usually includes a heavy duty steroid and at worst an IV filled with meds to offset the reaction — hospitalization for a week is kind of unheard of," the source said.

Miley Cyrus' friends also said that the "Wrecking Ball" singer's "hard-partying lifestyle" is what caused her body to inevitably collapse. She apparently had taken too many drugs to the point that she had to stay at the hospital for detoxing.
