Medication Options for Crohn’s Disease



Successful medical treatment allows your intestinal tissue to heal and it helps relieve symptoms such as fever, diarrhea, and abdominal pain.

There are several groups of drugs used to treat Crohn’s disease. Some of these options are used to get your symptoms under control, which is known as inducing remission. Medical therapy, also called maintaining remission or maintenance, is used to decrease the frequency of Crohn’s flares.


You and your health care provider are partners in your health. This list of common Crohn’s medications can help you begin an informed discussion with your doctor. Visit our IBD Medication Guide to view a comprehensive listing of all available medications for Crohn's disease.

Aminosalicylates (5-ASA)

These include medications that contain 5-aminosalicylic acid (5-ASA). These drugs are not specifically approved by the Food and Drug Administration (FDA) for use in Crohn’s, yet they can work to decrease inflammation in the lining of the GI tract.


Aminosalicylates are thought to be effective in treating mild-to-moderate episodes of Crohn’s disease and useful as a maintenance treatment in preventing relapses of the disease. They work best in the colon and are not particularly effective if the disease is limited to the small intestine.



  • Sulfasalazine

  • Mesalamine

  • Olsalazine

  • Balsalazide

Treating IBD: Aminosalicylates Aminosalicylates are compounds that contain 5-aminosalicylic acid (5-ASA) and reduce inflammation in the lining of the intestine. Watch this video to learn more.



Corticosteroids suppress the immune system and are used to treat moderate to severely active Crohn's disease. These drugs work non-specifically, meaning that they suppress the entire immune response, rather than targeting specific parts of the immune system that cause inflammation.


Corticosteroids have significant short- and long-term side effects and should not be used as a maintenance medication. If you cannot come off steroids without suffering a relapse of your symptoms, your doctor may need to prescribe other medications to help manage your disease.



These medications are available orally and rectally.

  • Prednisone

  • Methylprednisolone

Corticosteroids for IBD

Corticosteroids for IBD Corticosteroids are powerful and fast-acting anti-inflammatory drugs that have been frequently used in the treatment of acute flare-ups of IBD. Watch this video to learn more.



This class of medications modulates or suppresses the body’s immune system response so it cannot cause ongoing inflammation. Immunomodulators, which may take several months to begin working, are generally used when aminosalicylates and corticosteroids haven’t been effective, or have been only partially effective.


These medications may be useful in reducing or eliminating the need for corticosteroids, and in maintaining remission in people who haven’t responded to other medications given for this purpose.



  • Azathioprine

  • 6-mercaptopurine

  • Cyclosporine

  • Tacrolimus

Immunomodulators for IBD

Immunomodulators for IBD Immunomodulators weaken or modulate the activity of the immune system. And are medications often used to treat people with IBD. Watch this video to learn more.


Antibiotics may be to treat bacterial infections in the GI tract. Infections in Crohn’s disease can include abscesses and fistulas around the anal canal and vagina.



  • Metronidazole

  • Ampicillin

  • Ciprofloxacin

Biologic/Biosimilar Therapies

These medications are the latest class of therapy for people with Crohn's disease who have not responded well to conventional therapy. Biologics are antibodies grown in the laboratory that stop certain proteins in the body from causing inflammation.



  • Adalimumab

  • Certolizumab pegol

  • Infliximab (branded or unbranded)

  • Infliximab-dyyb

  • Natalizumab

  • Risankizumab-rzaa

  • Ustekinumab

  • Vedolizumab

Biologics for IBD

Video Length 00:01:21

Biologics for IBD Biologics are antibodies grown in the laboratory that stop specific proteins in the body from causing inflammation. Their mechanisms of action are more precisely targeted to the factors responsible for IBD.

Biosimilars are nearly identical copies of other already approved biologic therapies. They have the same effectiveness and safety as the originally approved biological therapy, in the target patient population.



  • Infliximab-abda

  • Infliximab-axxq

  • Infliximab-dyyb

  • Adalimumab-atto

  • Adalimumab-adbm

  • Adalimumab-aqvh

  • Adalimumab-adaz

  • Adalimumab-bwwd

  • Adalimumab-aaty

  • Adalimumab-aacf

  • Adalimumab-fkjp

  • Ustekinumab-auub



Targeted Synthetic Small Molecules


Targeted synthetic small molecules are medications that help reduce inflammation by specifically targeting parts of the immune system. The targets of these medications can play a role in intestinal inflammation. These medications are taken by mouth and are indicated for adults with moderately to severely active Crohn's disease who have had an inadequate response or intolerance to one or more TNF blockers.



  • Upadacitinib
  • Tofacitinib
  • Etrasimod
  • Ozanimod
