Consumer information for this interaction is not currently available.
MONITOR: Concomitant use of belimumab and rituximab may lead to an increase in the rate of severe adverse events and serious infections. Belimumab therapy alone has been associated with serious and sometimes fatal infections. In a double-blind, randomized, placebo-controlled, phase 3 trial in adults with systemic lupus erythematosus (SLE) receiving belimumab, the addition of rituximab was associated with serious adverse events in 22.2% and serious infections in 9% of patients, compared to 13.9% and 2.8% of patients, respectively, in the placebo add-on group. Clinical data are not available for other B-cell targeted therapies.
MANAGEMENT: According to the manufacturer of belimumab, available data do not support the coadministration of belimumab with rituximab in patients with SLE. Caution and monitoring for adverse reactions, particularly infections, is advised if concomitant use of belimumab with other biologic therapies with immunosuppressant effects, particularly B-cell targeted therapies including but not limited to ocrelizumab, ofatumumab, or obinutuzumab. Some authorities advise against their concomitant use.

Interferon beta-1b may cause liver problems, and using it with other medications that can also affect the liver such as ethanol may increase that risk. You should avoid or limit the use of alcohol while being treated with these medications. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark urine, pale stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Talk to your doctor or pharmacist if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
