It is unlikely that meropenom will reduce the effectiveness of remicade. However, meropenom is a potent antibiotic and as all antibiotics may sometimes produce side effects, such as diarrhea.

Also, you should keep in mind that remicade as well as methotrexate both suppress the immune response (in fact, that's why they alleviate auto-immune diseases, such as ankylosing spondilitis), and thus increase susceptibility to infections, including UTI.
