A father was left in a coma with his skin peeling off due to an allergic reaction to an over-the-counter dose of Ibuprofen, the Daily Mail reports.

Jason Ryan, 28, suffered from a severe allergic reaction which is believed to have been sparked by taking over-the-counter Ibuprofen. His condition is known as Stevens Johnson Syndrome (SJS) and causes the cells in his skin to die before shedding - very much like that of a snake. SJS is said to affect only two people out of a million every year and may become fatal if left untreated.

Ryan, who works as a production worker at Nissan was simply suffering from flu-like symptoms in May of last year. He took Ibuprofen which he normally takes in the past and has not developed any allergic reactions. Thus, Jason and his wife, Claire, did not automatically link the sudden growth of blisters on his skin to the drug. "He already had this rash, like shingles, and he was taking ibuprofen every four hours. It was all over his legs and his back, I knew it wasn't a sweat rash. He was taking the ibuprofen and the next day his feet came up in blisters like tennis balls," said Claire.

Mrs. Ryan immediately called for an ambulance but was advised to just go to the nearest walk-in center. "We should have known then. We were then told to go to the hospital. We could see it progressing; his skin was blistering." The couple found out that there is no cure for the condition. "Jason's body looked like a horror show, wherever he moved more skin would fall off. He was screaming. It was so raw. Nobody could tell us what was happening because nobody knew."
