Sonia Whyte-Croasdaile

​Founder / President

Sonia Whyte-Croasdaile RPN, RSW, is a wife, mother, nurse, Registered Social Worker, trained Relaxation/Life Coach, and the Founder and President of Stevens-Johnson Syndrome Canada. She is experienced in community-based work, support group development and facilitation, and couples, individual, and group counselling. Like many other professionals, Sonia aspired to maintain her professional career of over 25 years until she was ready for retirement. However, in 2011, she battled and survived Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN), a debilitating skin condition that has since completely transformed and rearranged her life.

For approximately six weeks in 2011, Sonia fought for her life in the Intensive Care Unit and Burn Unit alike in the hospital. After being discharged from the hospital, she stated that she felt like she had become a stranger to her own body. The body she once knew was now unrecognizable and painfully falling apart due to the burning of her skin and other membranes because of the disease. Sonia desperately and passionately searched for community resources to support her challenging recovery journey but found none. She realized then that community support for patients like her was non-existent in Canada. Having survived this life-changing ordeal, it has become her mission to create a Canadian-based organization to assist others on their journey with SJS/TEN. To fill that void, Sonia founded Stevens-Johnson Syndrome Canada with the help of her supportive family, friends, and medical experts in the field.

Sonia Whyte-Croasdaile frequently shares her story with the medical fraternity as well as and the general community to inspire hope, bring awareness, educate, and support within and outside of the SJS/TEN patient community. Through her efforts, the organization has reached and supported numerous individuals from all over the world. Her primary goal is to help this organization improve the lives of those affected by Stevens-Johnson Syndrome.  Please join us in supporting the cause of SJS Canada in its fight to bring awareness to and possible find a cure to this life-threatening disease, through your generous monetary donation, or offering your time to help the organization in its efforts to spread the word, solicits funds, or in any other way you can.

Jeremy Falk

Patient Representative

My name is Jeremy Falk and I live in Los Angeles. In 2005 I had a bacteria staph infection.  After taking two weeks of a 21-day supply of Bactrim (a Sulfa-based antibiotic), my eyes and throat started to feel inflamed and irritated. I went to the hospital and was told I had an eye infection and was giving sulfa eye drops in addition to the oral sulfa antibiotics that I was already taking. Later that day I developed bumps on my body, my face began to swell and the skin around my face started peeling and flaking. I took a picture and sent it to my dad and brother.  My brother’s pharmacist friend told him I was having a severe allergic reaction while my dad and I read up on the possible side effects of Bactrim. Everyone agreed I need to go to the ER now.

By the time I was admitted to the hospital, my eyes were swelled shut, my skin was peeling and raw from my scalp to torso. During my 13-day week stay in a quarantined hospital room, they stitched amniotic membrane to underside of my eyes lids in the hopes that I would not lose my vision. My family took me home and helped me recover.

After one month without sight, they removed the stitches from my eyes and I was able to see, thank goodness. However, my tear ducts no longer worked and I could barely open my eyes. They were extremely photosensitive and dry.

Years later In 2012, while working with the incredible team at USC Roski Eye Institute in Los Angeles I met Dr. Gloria Chiu. Dr Chiu specializes in caring for patients with extreme eye conditions, like my SJS-effected eyes. She introduced me to PROSE contacts, and that changed everything for my eyes and me. These custom-made prosthetic lenses allowed me to open my eyes more and drastically reduced the photosensitivity. PROSE also helps to decrease the irritation and redness of my eyes.

In 2020 I began the process of cataract surgery in both eyes. The healing process has proven to be tricky due to the dryness of my eyes. I am still healing due to accidental scratches during healing.

Other than my cataract surgery woes I am in good shape. Although my nailbeds are damaged and fragile from SJS and my finger nails don’t work very well, I am very grateful that I’m healthy and was able to resume my full life of continuing my career as an Apple Consultant, running regularly (including two marathons), and all the travel and activities I enjoy and love, including attending Burning Man!

In June 2020, I found and joined the SJS Canada group and have been delighted by the support that the group provides for each other.  Sonia’s care and attention to the members of this group is greatly appreciated, her leadership has helped gain awareness and momentum for the SJS community.  It has been a pleasure to be a part of this group. Thank you.

Dr. Bruce Carleton

Professor and Chair

Division of Translational Therapeutics, Department of Pediatrics

Faculty of Medicine

University of British Columbia


Pharmaceutical Outcomes Programme

BC Children’s Hospital

Senior Clinician Scientist

BC Children’s Hospital Research Institute Vancouver

Dr. Bruce Carleton has over 30 years of experience in clinical pharmacology and investigating the safety and effectiveness of drugs used in both children and adults. He is the founder and CEO of the Canadian Pharmacogenomics Network for Drug Safety (CPNDS), established in 2004 and based in Vancouver, BC. One of the overarching goals of the CPNDS is to prevent adverse drug reactions (ADRs) by identifying predictive genomic markers for specific ADRs through active surveillance. These markers are incorporated into diagnostic tools used to predict and prevent ADRs through specific dosing and alternative therapeutic recommendations for commonly used drugs. The CPNDS has established extensive collaborations within the province of BC, across Canada and internationally, to conduct patient-oriented research and disseminate findings to help patients.


One of the specific areas, where Dr. Carleton is a recognized leader whose scientific accomplishments have been acknowledged internationally, is in Severe Cutaneous Adverse Reactions (SCAR). His work has identified genetic variants that cause a variety of ADRs including carbamazepine-induced hypersensitivity reactions e.g., Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN), phenytoin-induced maculopapular exanthema, and the development of clinical practice guidelines for predictive pharmacogenetic testing.


In 2017, Dr. Carleton was invited and asked to speak at the SJS/TEN 2017: Building Multidisciplinary Networks to Drive Science and Translation Meeting, the second in a series of biennial meetings of experts to take place in North America. Dr. Carleton also hosted and chaired the organizing committee for the SJS/TEN 2019: From Science to Translation Meeting which successfully engaged 164 participants, including 43 SJS/TEN patients and their families from six continents. Establishing international network meetings is a significant component in advancing the science to understand these rare, severe ADRs as well as showcasing the latest innovations for treating SJS/TEN. Attendees are then able to further enhance the support systems and technologies to improve care for patients. Dr. Carleton continued his involvement and participation at the SJS/TEN 2021: Collaboration, Innovation and Community Meeting held virtually during the COVID-19 pandemic.


Dr. Carleton is currently investigating genomic causes of antibiotic-induced severe cutaneous adverse reactions in pediatric and adult patients, as well as common genetic traits for all drug-induced serious cutaneous adverse reactions.

Dr. Elizabeth Phillips is a physician-scientist clinically trained in infectious diseases, immunology, and clinical pharmacology who has established new clinical and research programs in drug hypersensitivity, pharmacogenomics, and personalized immunology across different healthcare systems. She has published over 350 peer-reviewed articles and book chapters on hypersensitivity reactions to drugs and vaccines.

For over 25 years, Dr. Phillips has led research programs in Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) and other severe immune-mediated adverse drug reactions across different medical systems. She is recognized for elucidating mechanisms and genetic determinants of drug hypersensitivity, which have transformed research, clinical practice, and training in the United States and internationally. Her discovery through a translation pipeline continues to pioneer strategies to prevent, diagnose, and mitigate harm from true drug hypersensitivity. She is also applying novel technologies to understand the single-cell pathology of drug hypersensitivity at the site of tissue damage, leading to the identification of new therapeutic targets. Additionally, Dr. Phillips is a principal investigator on National Institutes of Health (NIH) funded research to define genetic and other markers that can lead to the prediction, prevention, and earlier diagnosis of SCARs, including the North American Therapeutics In Epidermal Necrolysis Syndrome (NATIENS) study to determine the most effective treatment for SJS/TEN.

Dr. Phillips has also led the development of clinical guidance and practices related to the care of drug hypersensitivity in patients. She presently dedicates her clinical outpatient practice to drug hypersensitivity at VUMC and her clinics have acted as a model for others within the United States and abroad, and her efforts have transformed care across multiple disciplines.

An additional passion of Dr. Phillips is advocating for members of the community with severe cutaneous adverse drug reactions and working alongside patients and foundations to advance education, awareness, and science of drug hypersensitivity. She founded and led SJS/TEN 2017, 2019, 2021, and 2023 meetings and the DRESS 2022 meeting to unite science with the community. These meetings have provided a diversity of scientific information to an international audience. The SJS/TEN 2023 meeting, for example, drew an overall attendance of 428 individuals from 57 countries, including 72 representatives of the SJS/TEN community and 356 members of the scientific community.
