Examples

Sulfasalazine is a combination of salicylic acid (the active ingredient in aspirin) and an antibiotic, sulfapyridine.

How It Works

Sulfasalazine may reduce joint inflammation caused by juvenile idiopathic arthritis (JIA).

Why It Is Used

Sulfasalazine is considered a second-line treatment for JIA. Its use is reserved for children with JIA who do not respond to nonsteroidal anti-inflammatory drugs (NSAIDs) or methotrexate. Children who are allergic to sulfa medicines or salicylates cannot use this medicine.

How Well It Works

Some data indicate that the use of sulfasalazine is effective in the treatment of JIA, particularly children with polyarticular JIA and oligoarticular JIA.²

Side Effects

All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine your child takes. Side effects are also listed in the information that comes with the medicine.

Here are some important things to think about:

• Usually the benefits of the medicine are more important than any minor side effects.
• Side effects may go away after your child takes the medicine for a while.
• If side effects still bother your child and you wonder if he or she should keep taking the medicine, call your doctor. He or she may be able to lower the dose or change the medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.

Call 911 or other emergency services right away if your child has:

• Trouble breathing.
• Hives.
• Swelling of your face, lips, tongue, or throat.

Call your doctor right away if your child has:

• Aching joints.
• A continuing headache.
• Itching or a rash.

Common side effects of this medicine include:

• Skin sensitivity to sunlight.
• Stomach pain, nausea, loss of appetite.
• Diarrhea.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

What To Think About

Children with systemic JIA are most likely to experience severe side effects, so they are not treated with sulfasalazine.¹

Positive effects from sulfasalazine treatment can take 1 to 3 months to become apparent, which is faster than some other second-line medicines.¹

Sulfasalazine is considered safer, but is generally less effective, than methotrexate. A child who can't take or hasn't responded to first-line NSAID treatment or to methotrexate may be given sulfasalazine.
