Cefdinir
"I took this medication on Christmas Eve in 2015. Twenty minutes after taking a single pill, I don't remember the dosage, I completely blacked out. My face had gotten extremely red and I had dropped an entire plate of hot food on myself. My mother changed my clothes and I woke up an hour later, not knowing what had happened, and wondering why I was wearing different clothes. One half of my tongue was numb for about a week and a half. It was an absolutely terrifying experience."
