We're glad you found us.

National DRESS Syndrome Day is July 16! Join us in building awareness.


DRESS Syndrome is a severe, cutaneous, adverse, delayed reaction from primarily taking one of over 50 medications. This life-threatening condition can cause major organ dysfunction and may result in long-term complications.

DRESS stands for Drug Reaction with Eosinophilia and Systemic Symptoms. The condition also goes by the name Drug-Induced Hypersensitivity Syndrome (DIHS).

The first symptoms of DRESS Syndrome are usually a fever followed by a rash and, often, facial swelling. DRESS symptoms can progress to severely affect multiple organs, including the liver, kidneys, lungs, and heart. Some of these symptoms can emerge weeks to months after the first signs of DRESS show, meaning doctors should monitor patients for a long time.

Is DRESS Syndrome rare?

While currently thought of as a "rare" condition, it is under-diagnosed and under-reported, and many doctors have never treated a DRESS patient. To date, 1 in 1,000 to 1 in 10,000 people may develop DRESS Syndrome. Many patients have been in and out of the ER, are hospitalized, and undergo many tests before receiving a DRESS diagnosis.

Fortunately, you can find a way forward.

We understand what you're going through.

You are not alone.
