Treating Crohn's With Biologics: Drugs at a Glance
Biologic drugs can be a good option to help make your
Crohn's symptoms go away and prevent new flare-ups. To do this, they attack enzymes or proteins that inflame your intestine.
Biologics don't suppress your whole immune system, as steroids tend to, so they are less likely to cause major side effects.

There are four biologic drugs approved to treat
Crohn's disease. Three of them are in the class of drugs known as TNF-blockers:
Tysabri ( natalizumab), the fourth biologic drug, is in the drug class known as monoclonal antibodies.
Cimzia. This drug is given as a shot. After your first shot, you get injections at 2 and 4 weeks. After that you get a shot every 4 weeks.
Humira. This is also given as a shot. You'll need to take a shot every 2 weeks.
