The following sections explain in detail the potentially negative interactions that can occur when Rituxan is combined with any of the drugs listed above.
If you have taken abciximab in the past, you may be at a higher risk for certain Rituxan side effects (and vice versa as well -- if you have taken Rituxan before, you might be at a higher risk for certain abciximab side effects). This is due to the formation of antibodies to certain types of monoclonal medications. Your healthcare provider will need to monitor you more closely in this case.
