Azulfidine vs. Azulfidine EN-tabs

Both Azulfidine and Azulfidine EN-tabs come as oral tablets. Azulfidine EN-tabs are a delayed-release form of Azulfidine. “EN-tabs” stands for enteric-coated tablets. The coating delays the breakdown of the tablets until they reach your intestines. This allows the drug to be released into the body slowly throughout the day instead of all at once. To learn more, see the “Azulfidine and Azulfidine EN-tabs dosage” section below.

Azulfidine and Azulfidine EN-tabs contain the same active ingredient, sulfasalazine. They belong to a group of drugs called disease-modifying antirheumatic drugs (DMARDs). Both Azulfidine and Azulfidine EN-tabs are available in one strength: 500 milligrams (mg).

For information about the effectiveness of Azulfidine and Azulfidine EN-tabs, see the “Azulfidine and Azulfidine EN-tabs uses” section below.

Azulfidine and Azulfidine EN-tabs are brand-name drugs that contain the active drug sulfasalazine. This active drug is also available as a generic medication. A generic drug is an exact copy of the active drug in a brand-name medication.

Azulfidine is available in a generic form called sulfasalazine. Azulfidine EN-tabs are available in a generic form called sulfasalazine delayed-release.

The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Drug forms and strengths

Azulfidine and Azulfidine EN-tabs both come as oral tablets in one strength: 500 milligrams (mg).

Azulfidine EN-tabs are a delayed-release form of Azulfidine. “EN-tabs” stands for enteric-coated tablets. The coating delays the breakdown of the tablets until they reach your intestines. This allows the drug to be released into the body slowly throughout the day instead of all at once.

Azulfidine EN-tabs are recommended for people with ulcerative colitis who have taken Azulfidine and had side effects such as nausea and vomiting. Because Azulfidine EN-tabs are released more slowly than Azulfidine, they may cause fewer and less severe side effects.

Dosage for ulcerative colitis

The starting dosage of Azulfidine or Azulfidine EN-tabs for ulcerative colitis is a total of 3 grams (g) to 4 g per day. These doses are divided into multiple doses per day. For example, your doctor may have you first take 1,000 mg (1 g) every 6 hours. If you have side effects from the starting dose, they may decrease your dose.

Once your body builds a tolerance to the medication and your symptoms improve, your doctor may reduce your dose to a maintenance dose. Usually, the maintenance dosage for ulcerative colitis is a total of 2 grams per day, which may be split into multiple doses. For example, you may take 500 mg (0.5 g) every 6 hours.

Dosage for rheumatoid arthritis

When you first start taking Azulfidine EN-tabs for rheumatoid arthritis (RA), your doctor may recommend a low starting dose so your body can adjust to the medication. For example, they may recommend 500 mg once or twice daily to begin.

Once your body is used to Azulfidine EN-tabs, your doctor may increase your dose. The maintenance dosage of Azulfidine EN-tabs for RA is 2 grams (2,000 mg) per day, divided into two doses. So your doctor may recommend taking 1,000 mg twice per day.

This example of a dosing table shows how your doctor may recommend taking Azulfidine EN-tabs for RA:

Azulfidine is not approved to be used for RA.

Dosage for juvenile idiopathic arthritis

The dosage of Azulfidine EN-tabs for children ages 6 years and older with polyarticular* juvenile idiopathic arthritis (JIA) is based on body weight. The recommended dosage is 30 mg to 50 mg per kilogram (kg)† of body weight per day. This dose should be divided into two doses per day.

Here’s an example for a child who weighs 40 kg, which is about 88 pounds (lb). Their dosage would be between 1,200 mg and 2,000 mg per day. Their doctor may recommend a dose of 500 mg in the morning and 1,000 mg at night, or 1,000 mg twice per day.

The maximum dosage of Azulfidine EN-tabs in children with JIA is 2,000 mg per day.

Azulfidine is not approved to be used in children with JIA.

* Polyarticular arthritis affects five or more joints. † 1 kg is about 2.2 lb.

With an autoimmune condition, your immune system mistakenly attacks your own body and causes the symptoms you experience.

Will Azulfidine or Azulfidine EN-tabs cure my condition?

No, Azulfidine or Azulfidine EN-tabs will not cure ulcerative colitis, rheumatoid arthritis, or juvenile idiopathic arthritis (JIA). In fact, there are no cures for these conditions.

Azulfidine and Azulfidine EN-tabs should work to ease the symptoms of your condition. Your doctor can help determine if either drug is right for you.

Are Azulfidine and Azulfidine EN-tabs steroids?

Azulfidine and Azulfidine EN-tabs are not steroids. These two medications belong to a group of drugs called disease modifying anti-rheumatic drugs (DMARDs).

Both steroids and DMARDs may be used to treat autoimmune conditions.

It’s not known exactly how these medications work to treat ulcerative colitis, rheumatoid arthritis, or JIA. However, these conditions are all caused by your immune system mistakenly attacking your own body. It’s thought that Azulfidine and Azulfidine EN-tabs decrease the swelling that your immune system causes, which eases symptoms. In addition, the drug may weaken your immune system so that it doesn’t attack your body.

Steroid medications may also be used to treat autoimmune conditions. For example, you may take prednisone, which is a steroid. Steroids and DMARDs work in different ways to treat your condition.

Can I switch from Azulfidine to Azulfidine EN-tabs, or vice versa?

Yes, in most cases your doctor can switch you from Azulfidine to Azulfidine EN-tabs, or vice versa.

Both drugs contain the same active medication, sulfasalazine. The difference between the drugs is the way the medication releases in your body. Azulfidine releases as soon as you take your dose. However, Azulfidine EN-tabs are delayed-release, so the medication releases in your body slowly over time. This can decrease nausea and vomiting that you may experience from Azulfidine.
