Thank you for asking on HCM! Remicade (infliximab) & Humira (adalimumab) belongs to the same drug class and both of them are effective in Crohn s disease, because they reduce inflammation of bowel. Most common side effects of Remicade are: Abdominal or stomach pain cough dizziness fainting flushing of the face headache itching muscle pain nasal congestion vomiting, etc. While some people using Humira have developed a rare fast-growing type of lymphoma (cancer that affects the liver, spleen, and bone marrow, and it can be fatal), I recommend to use Remicade. Call your doctor at once if you have: -signs of infection (fever, chills, flu symptoms, confusion, or pain, warmth, or redness of your skin); -signs of tuberculosis (fever, cough, night sweats, loss of appetite, weight loss, feeling constantly tired); -chest pain, ongoing cough, coughing up mucus or blood. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
