Madonna’s hospital scare last week was even scarier than first thought. RadarOnline.com reported Thursday that the pop icon had to be revived with Narcan to combat septic shock. The 64-year-old was rushed to the hospital on June 24 after she was found unresponsive in New York. She had “developed a serious bacterial infection which led to a several day stay in the ICU,” her manager Guy Oseary said last week. That’s where she was reportedly revived with the Narcan and intubated for at least a night. While Narcan is typically used to reverse a drug overdose—there was no evidence of Madonna overdosing—its ability to rapidly raise a person’s blood pressure makes it a potentially effective treatment for septic shock. The medical scare led to Madonna’s “Celebration” tour being postponed after it was initially slated to start July 15.
