Crohn’s Disease

The main treatment for Crohn’s disease is medicine to stop the inflammation in the intestine and medicine to prevent flare-ups and keep you in remission. A few people have severe, persistent symptoms or complications that may require a stronger medicine, a combination of medicines, or surgery. The type of symptoms you have and how bad they are will determine the treatment you need.

Initial treatment

Your doctor will most likely start with the traditional first-line treatment for Crohn’s disease. He or she will then add or change medicines if you are not getting better.

Mild symptoms may respond to an antidiarrheal medicine such as loperamide (Imodium, for example), which slows or stops the painful spasms in your intestines that cause symptoms.

For mild to moderate symptoms, your doctor will probably have you take:

  • Aminosalicylates (such as sulfasalazine or mesalamine). These medicines help manage symptoms for many people who have Crohn’s disease.
  • Antibiotics (such as ciprofloxacin ormetronidazole). These may be tried if aminosalicylates are not helping. They are also used to treat fistulas and abscesses.
  • Corticosteroids (such as budesonide orprednisone). These may be given by mouth for a few weeks or months to control inflammation. But corticosteroids have serious side effects, such as high blood pressure, osteoporosis, and increased risk of infection.
  • Medicines that suppress the immune system (called immunomodulator medicines), such as azathioprine or mercaptopurine. You may take these if the medicines listed above do not work, if your symptoms come back when you stop taking corticosteroids, or if your symptoms come back often, even with treatment.
  • Biologics (such as infliximab or adalimumab). Your doctor may have you try these medicines if you have not had success with other medicines for Crohn’s disease. In some cases, these medicines are tried before some of the other medicines that are listed above. They are also used to treat fistulas.

Severe symptoms may be treated with corticosteroids given through a vein (intravenous, IV) or biologics. With severe symptoms, the first step is to control the disease. When your symptoms are gone, your doctor will probably have you start taking one of the medicines listed above to keep you symptom-free (in remission).

Ongoing Treatment

Ongoing treatment is designed to find a medicine or combination of medicines that keeps Crohn’s disease in remission.

If aminosalicylates or immune system suppressors keep your disease in remission, you will continue taking the medicines. Your doctor will want to see you about every 6 months if your condition is stable or more frequently if you have flare-ups. You may have lab tests every 2 to 3 months.

Corticosteroids may be given to stop inflammation if you have flare-ups of symptoms. If you need to take corticosteroids for an extended time, you also may receive calcium, vitamin D, and prescription medicine to prevent osteoporosis.

Biologics are also used as maintenance medicines.

Treatment If the Condition Gets Worse

If you have a very bad flare-up of Crohn’s disease, you will most likely need IV corticosteroids (like hydrocortisone) to get the disease under control.

Some severe cases of Crohn’s disease need to be treated in the hospital where you would receive supplemental nutrition through a tube placed in your nose and down into the stomach (enteral nutrition). In other cases, the bowel may need to rest, and you will be fed liquid nutrients in a vein (total parenteral nutrition, TPN). Supplemental nutrition may be needed if you are malnourished because of severe Crohn’s disease in the small intestine. Nutritional support is especially important for children who are not growing normally because of severe disease.

Surgery may be needed if no medicine is effective, if you have serious side effects from medicine, if your symptoms can be controlled only with long-term use of corticosteroids, or if you develop complications such as fistulas, abscesses, or bowel obstructions. Surgery involves removing the affected portion of the intestines, preserving as much of the intestines as possible to maintain normal function. Crohn’s disease tends to return to other areas of the intestines after surgery.
