Yes Remicade can cause hair loss as side effect. It also rarely (2%) of patients can get a lupus-like reaction to Remicade. This could cause hair loss, severe fatigue, joint pains, pleurisy, bad aching pain in extremities, etc. If you have any of these other symptoms, I would notify your Dr, and ask to get an ANA and anti-histone antibodies checked on blood. If positive, Remicade is usually stopped and something else done for the Crohn's.
