Stevens-Johnson Syndrome (SJS) Stevens-Johnson syndrome, also called SJS, is a rare but serious problem. Most often, it's a severe reaction to a medicine you've taken. It causes your skin to blister and peel off. It affects your mucus membranes, too. Blisters also form inside your body, making it hard to eat, swallow, even pee.

Getting treated right away helps protect your skin and other organs from lasting damage.

Symptoms

SJS usually starts with a fever and feeling like you have the flu. A few days later, other symptoms appear, including:

• Painful red or purple skin that looks burned and peels off
• Blisters on your skin, mouth, nose, and genitals
• Red, painful, watery eyes

SJS is dangerous. If you have these symptoms, go to the emergency room.

Causes of SJS

More than 100 drugs can cause SJS. Some of the most common are:

• Medicines for gout, a painful form of arthritis -- especially allopurinol (Aloprim, Zyloprim)
• Pain relievers such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), and naproxen sodium (Aleve)
• Sulfa antibiotics, a kind of drug that fights infections (including Bactrim and Septra)
• Medicines that treat seizures or mental illness

The medicines most likely to cause problems in kids are sulfa antibiotics, Tylenol, and drugs that treat seizures, especially carbamazepine (Carbatrol, Tegretol).

If you're going to get SJS, it will most likely happen in the first 2 months you're taking a drug.

An infection, like pneumonia or the herpes virus that causes cold sores, can also trigger SJS. This happens more often with kids than adults.

You're more likely to get SJS if you have:

• HIV or other problems with your immune system
• Had SJS before
• Certain genes you inherit from your parents
• Radiation treatments

Treatment

You'll be treated for SJS in the hospital by a special team of doctors and nurses. Some people are treated in a burn center or intensive care unit.

The first thing doctors will do is to stop the medication or treat the infection that made you sick. They'll also try to relieve your symptoms, prevent infections, and support your healing.

Replace fluids and nutrients. Your body needs to stay hydrated, and your skin needs protein to rebuild. You'll probably get fluids from an IV at first, then be fed through a tube that goes into your stomach through your nose.
