Story highlights An allergic reaction to an antibiotic sent Yaasmeen Castanada to a hospital burn unit 
 
 "It has just spiraled into a nightmare," her aunt told CNN affiliate KABC 
 
 A doctor says the teen's prognosis is good, but she's in critical condition 
 
 (CNN) It started with a sore throat on Thanksgiving and an antibiotic from a friend who wanted to help. 
 
 Now 19-year-old Yaasmeen Castanada is fighting for her life inside a California hospital's burn unit, suffering from an allergic reaction that's so severe she has large open wounds all over her body. 
 
 "It is heartbreaking, every day is a different look. Every day, she's like, shedding away. ... Overnight, it's a whole different person that you're looking at," Martha Hughes, Castanada's aunt, told CNN affiliate KABC. 
 
 Doctors diagnosed Castanada with Stevens-Johnson Syndrome, a rare disease that can be triggered by antibiotics or other medications. 
 
 "When she took the medication, she started having a hard time breathing, and she told her mom that her lips were burning, her throat, her eyes, they got so red that she couldn't talk. So she rushed her to the ER, and that's when they diagnosed her with the disease. And from there it has just spiraled to a nightmare," Hughes said. 
 
 Now Castanada, the mother of a 4-month-old, is in critical condition at the University of California, Irvine, burn center. 
 
 Her prognosis is good, even though the disease has a high mortality rate, according to Dr. Victor Joe, the center's director. 
 
 But the situation, Castanada's family says, has been devastating. 
 
 "Just unreal, just watching your daughter burn in front of you, literally, burn in front of you," her mother, Laura Corona, told KABC. "Every day, a new blister, a new burn, a new scar. And she's just, 'Mommy, I want to go home.' And I can't take her home. I can't put water on her lips." 
 
 Mom: 'Don't share medication' 
 
 On a website created to raise funds for Castanada's care, her mother said the harrowing ordeal began soon after her daughter took the medicine. 
 
 "A friend offered her an antibiotic pill that she had from a previous illness," Corona wrote. "She was thinking that it would help her. This would be the biggest mistake of her life." 
 
 Now, Corona says she's hoping to spread the word so others don't make the same mistake. 
 
 "Don't share medication. Don't give someone else your medication. Don't offer medication," she said. 
 
 She also advises parents to find out what their children are allergic to -- before it's too late. 
 
 Doctor: Reaction causing skin to separate 
 
 At first, doctors diagnosed Castanada with Stevens-Johnson Syndrome, which refers to a condition where between 10% and 30% of the skin on the body is affected, Joe said. Now she's experiencing Toxic Epidermal Necrolysis, the diagnosis when more than 30% of the body is affected. Joe estimates that 65% of Castaneda's skin and mucus membranes have been affected. 
 
 The allergic reaction is causing layers of Castaneda's skin to separate, Joe said, creating lesions that grow into large open wounds. 
 
 "Patients can experience problems with taste, swallowing, eyesight and sexual functions can be affected. In Yaasmeen's case, we are particularly concerned because her eyes have been affected. This can cause scarring of the corneas, which could lead to permanent blindness," he said. "We are trying to prevent that from happening." 
 
 Photos on the fundraising website show Castanada lying in a hospital bed, with openings for her eyes cut from the bandages that cover her. 
 
 As part of her treatment for the disease, doctors have wrapped her body in a special dressing, Joe said. 
 
 "We have chosen to place a dressing that adheres to the open wound, which allows her skin to heal without having to remove the bandages to wash the wounds," he said. 
 
 Mortality for those suffering from Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis can be as high as 25% in adults, but tends to be lower with early treatment, according to the Merck Manual. 
 
 Though it's uncommon, Joe said his hospital has treated around six cases in the past year, because the burn center has experience treating open wounds. 
 
 "This is very sobering. The fact that you can get a life-threatening situation from taking a medication. It can happen, and most people don't think twice about taking pills for things," Joe said. "In fact, most of the time you do have some sort of side reaction to medication, just not this severe." 
 
 After recovering from Stevens-Johnson Syndrome, patients usually only have minor issues with their skin, such as dryness, Joe said. 
 
 "Hopefully new skin will come in," Corona told KABC. "I'm just there watching. All I can tell her is, "Hang on, hang on. It's almost over.'" ||||| A young woman is in intensive care after having an allergic reaction to her friend's medication that has caused her body to burn from the inside out."Heartbreaking, just unreal.

 On Thanksgiving Yaasmeen was feeling ill. Common cold, sore throat. A friend offered her an antibiotic pill that her friend had from a previous illness. She was thinking that it would help her, but this would be the biggest mistake of her life. After taking the pill , Yaasmeen started experiencing burning in her throat, eyes and mouth. As the night went by, her eyes became blood shot red and the lining of her lips was already torn off. I rushed her to the ER . The dr's immediately diagnosed her with Stevens-Johnson Syndrome. Something I've never heard about. Immediately I googled Stevens Johnson's and I began to panic. In my mind I knew this couldn't happen to my baby, but deep down in the pit of my stomach was a terrible, terrible feeling. Within 4 days Yaasmeen's appearance was transformed. I watched my daughter's skin burn, blister, bubble, n peel off and there was nothing I could do about it. The pain and agony she was going through just tore my heart to pieces. She was transferred to UCIrvine's burn unit. On December 5th she has surgery to scrape the top portion of her body. She was wrapped in biobrane. 2days later the bottom portion of her body was scraped. As you can see in the photo, she was wrapped in bandages from hed to toe. My daughter was intubated so she couldn't communicate with me. i made sure i prayed over her daily, I spoke to her daily and reminded her that she had a daughter that loved her very much. Everyday i told her to fight for her life. Yaasmeens blood was infected and she has had 5 blood trasfusions. As we got closer to recovery, she had a set back. She was having a hard time breathing. After multiple exams of her trachea, they noticed her airway was closing so she had an emergency tracheotomy. she had her trach for 6months. There have been times where she had trouble breathing. She had another surgery in april to open her airway because it closed and the steriod injections didn't work. On my birthday June 18th she had surgery to reconstruct her trachea. She was able to sing happy birthday to me as soon as the anesthesia wore off. Best gift ever! Today 6/25 Yaasmeen had her stitches removed. Yay! Her left eye is very damaged, she will need a cornea transplant. Hopefully in 6-8 months when she is healthier we can face that surgery. As for now, she will just work on getting healthier and spending a lot of time with her daughter Khloe and return to CSULA! This whole expierence has taught me to never take my children for granted. I almost lost my daughter to 1 pill! She never smoke or drank, she is a good kid that was on the right path. I just can't understand why this happened the way it did. But we will not dwell in the past, She has goals and a bright future ahead of her. I thank all of you for your love, support and prayers for my daughter. *Please be careful with medications because an allergic reaction can happen to anyone. #prayforyaas

 Doctors at a Syracuse hospital came within inches of harvesting the organs of a live woman who woke on the operating table, despite previous reports by nurses indicating she was alive. 
 
 Doctors at St. Joseph's Hospital Health Center mistakenly ruled that Colleen S. Burns, 41, had suffered a cardiac death in October 2009, according to records published Sunday by the Syracuse Post-Standard behind a $22,000 fine issued by the state department of health. 
 
 The mother of three from North Syracuse had overdosed on Xanax, Benadryl and a muscle relaxant but had not died, only slipped into a deep coma, it would later be revealed. 
 
 She was mistakenly declared brain dead by hospital staff, with the tragic news presented to Burns' family who gave doctors permission to take her off life support and harvest her organs. 
 
 According to hospital records, one day before Burns' organs were to be removed, a nurse noticed something eerie about the patient, a sign someone without a medical degree may even jump to see. 
 
 Her toes curled from the simple reflex test of running a finger along her foot. 
 
 An investigation by the Health Department determined this and several other signs to come were shockingly ignored by doctors. 
 
 Then, just before surgery on Oct. 20, 2009, Burns' nostrils were seen flared as though she was breathing independent of her respirator. Her lips and tongue were seen moving as well. 
 
 Despite these signs, a nurse injected Burns with a sedative called Ativan just 20 minutes later, according to hospital records. 
 
 In contrast to these records, the doctor's notes show neither acknowledgement of Burns' movements nor the administration of Ativan. 
 
 Just when the surgery was to begin, Burns' eyes opened and gazed up at the bright lights hanging over her. It took that final sign to call it off. 
 
 Burns was later discharged from the hospital after a two-week stay. 
 
 Neither Burns nor her family filed a lawsuit against the hospital or doctors after the horrific incident. 
 
 Her mother, Lucille Kuss, explained her daughter was too depressed to care at that point in her life. 
 
 Tragically, Burns committed suicide 16 months later, dying of an overdose in January 2011. 
 
 Still, Kuss says the hospital never explained to them what went wrong in that dreadful first stay. 
 
 The Health Department would later find that hospital officials did not thoroughly investigate her near-death by their own hands until a surprise inspection in March 2010. 
 
 The day after, St Joe's issued a one-page report citing "perception differences" that did not include analysis of the cause of its mistake, according to the state's response obtained by The Post-Standard. 
 
 "The hospital did not undertake an intensive and critical review of the near catastrophic event in this case," the report said. 
 
 St. Joe's officials did not "identify the inadequate physician evaluations of (Burns) that occurred when nursing staff questioned possible signs of improving neurological function." 
 
 They further accused the hospital of insufficient brain scans, insufficient testing to determine if their patient was drug-free, failing to administer treatment that prevents a drug taken by a patient from being absorbed by the stomach and intestine, and ignoring a nurse's claims that Burns was not dead but improving. 
 
 The state fined the hospital $22,000 — $6,000 for Burns' case and $16,000 for an incident in 2011 where a patient received a head injury after being left unattended. 
 
 The state additionally ordered the hospital to hire a consultant to review the facility's quality assurance program, to implement that consultant's recommendations, and to hire a consulting neurologist to teach the staff how to accurately diagnose a brain death. 
 
 The hospital responded with a plan of action. 
 
 In a statement released by the hospital to the Daily News, St. Joe’s shared its grief over the terrifying mistake and said it contacted Burns' family to make matters rights. 
 
 The organization added that her family asked it not to publicly discuss what transpired. 
 
 "St. Joseph's provides compassionate care to more than 2,000 people every day throughout our system. Anytime something doesn't go right, we take it extremely seriously. In this case, we have made personnel and policy changes and re-examined everything we do related to quality," the hospital said.

– In a case both bizarre and horrifying, a 19-year-old California woman is burning from the inside out. How that's possible: an allergic reaction. Yaasmeen Castanada, a 19-year-old Cal State LA sophomore and mother to a 4-month-old, was battling a sore throat on Thanksgiving, so she took a friend's antibiotic, reports CNN. She rapidly "started having a hard time breathing, and she told her mom that her lips were burning, her throat, her eyes, they got so red that she couldn't talk," says her aunt. Within 24 hours she was hooked up to a ventilator; she's now at the University of California, Irvine, burn center. Her initial diagnosis was known as Stevens-Johnson Syndrome, an allergic reaction that caused her skin's layers to part, resulting in open wounds. "It can be considered a burn from the inside out," a dermatologist tells ABC7. But as burn center director Dr. Victor Joe tells CNN, that disease refers to a condition that affects up to a third of the skin; roughly two-thirds of Castanada's skin is affected, and her condition is now called Toxic Epidermal Necrolysis. Though the mortality rate for the diseases can reach as high as 25%, Joe believes she will survive. But he says "we are particularly concerned because her eyes have been affected. This can cause scarring of the corneas, which could lead to permanent blindness." Per a GoFundMe page set up by her family, Castanada has had surgeries since Friday on the top and bottom portions of her body in which skin was scraped to spur new growth. Joe calls the case "sobering" and notes that it's one of about half-a-dozen his unit has seen in the last year. (Last month, a peanut allergy killed a college student.)
