Benlysta Disease Interactions

In clinical trials, depression and suicidality were reported in patients receiving belimumab. Before treatment with belimumab, the risk of depression and suicide should be assessed, considering the patient's medical history and current psychiatric status; patients should continue to be monitored during therapy. Patients receiving belimumab (and caregivers, if applicable) should be instructed to contact their health care provider if they experience new or worsening depression, suicidal thoughts or behaviors, or other mood changes. The risk and benefit of continued therapy should be considered for patients who develop such symptoms.

Serious and sometimes fatal infections have been reported in patients receiving immunosuppressive agents (including belimumab). Overall, while the incidence of serious infections in controlled trials was similar between belimumab and placebo, fatal infection occurred more often with belimumab. The risk and benefit should be considered before starting treatment with belimumab in patients with severe or chronic infections. Interruption of therapy should be considered in patients who develop a new infection while receiving belimumab and these patients should be monitored closely.

Cases of John Cunningham virus (JC virus)-associated progressive multifocal leukoencephalopathy (PML) resulting in neurological deficits (including fatal cases) have been reported in patients with systemic lupus erythematosus receiving immunosuppressants (including belimumab). Risk factors for PML include treatment with immunosuppressant therapies and impairment of immune function. The diagnosis of PML should be considered in any patient presenting with new-onset or deteriorating neurological signs/symptoms; a neurologist or other appropriate specialist should be consulted as clinically indicated. If PML is confirmed, belimumab should be discontinued.
