Beyoncé’s younger sister, Solange Knowles, was admitted to a hospital after suffering from an adverse reaction to Vicks NyQuil pills onboard a flight from New York on Tuesday, intouchweekly.com reports.

The incident unfolded in front of fans’ eyes as she posted throughout the trip on her twitter.com page. “I think maybe I’m getting high off it because I’m not sleeping,” said Solange. “I didn’t know Nyquil could do this to you.” After an unsuccessful attempt to sleep, she added, “think I’m certified loosing it.”

Soon, the R&B singer did get to close her eyes, but not in the way she expected: She passed out in baggage claim, the website reports. “How’d I end up in the hospital? ... Guess I passed out!” Solange was then hooked up to an IV due to dehydration and low blood pressure. “I’m like still in shock. I’ve never passed out before.”
