In older patients or in lupus patients who already have kidney or blood pressure problems, commonly seen side effects include fluid retention, high blood pressure and reduced kidney function. In young, otherwise healthy people, these side effects are not common. Patients with lupus nephritis often have some reduction in kidney function. Patients with active lupus appear to be especially susceptible to this side effect.
