Im told i need to take remicade, (infliximab) im worried about what the most common side effect is and is cancer somthing i should be concerned about getting ?

Mild: Cancer is unlikely. Data suggest that only risk of non-melanoma skin cancer is slightly increased from remicade (infliximab). Most common side effects are common infections, headache, abdominal pain and infusion reactions. Most are mild.

Possibly: Remicade (infliximab) increases infections, including sinus/respiratory infections and severe infections (fungus or tuberculosis.) allergic reaction during infusion is a common side effect. It also increases risk for cancer, particularly lymphomas (3-4x increased risk). Head and neck cancers are increased in people with copd. Really ask your doctor about this so you can balance your risks and benefits.
