DRESS Syndrome (Drug Reaction with Eosinophilia and Systemic Symptoms) — also known as Drug-Induced Hypersensitivity Syndrome (DIHS) — is a potentially life-threatening delayed drug reaction that can appear weeks after starting a medication. DRESS can affect multiple organs and cause a wide range of body responses, often making it difficult to recognize and diagnose.

It is estimated to occur in 1 in 1,000 to 1 in 10,000 exposures to certain high-risk medications.

Currently, there are very few large databases that collect information about DRESS cases. By registering your case with us, you help improve understanding of DRESS — including the drugs that can cause it and the complications patients may experience.
+
We work with medical researchers studying the genetic, immune, and other aspects of DRESS to learn more about the condition and its long-term effects. With your permission, we may contact you about a study that could be relevant to your case.
+
Your privacy matters.
+
We never share any personally identifiable information — including with researchers — without your explicit permission. If a relevant study becomes available, the DRESS Syndrome Foundation will contact you first to ask whether you’d like to participate or be connected with the research team.
+
To advance research on DRESS and keep our community informed, we may share summary data or non-identifying details with researchers or, when appropriate, with the public.

Thank you for helping to expand knowledge of DRESS Syndrome and improve care for those affected by it.
