General

The most commonly reported adverse events include proteinuria, increased serum creatinine, neutropenia, decreased serum bicarbonate, decreased intraocular pressure, fever, and infection.[Ref]

Renal

Very common (10% or more): Proteinuria (up to 88%), elevated creatinine (up to 24%), nephrotoxicity (up to 59%)

Nephrotoxicity may be irreversible. Renal impairment, including cases of acute renal failure resulting in dialysis and/or contributing to death, has occurred with as few as one or two doses of the drug. Proteinuria (greater than 2+), reduced creatinine clearance (less than or equal to 55 mL/min), and/or elevations of serum creatinine concentration (greater than 0.4 mg/dL) occurred in about 59% of patients receiving a maintenance dose of 5 mg/kg every other week. Toxic nephropathy has also been reported.[Ref]

Ocular

The risk of ocular hypotony may be increased in patients with diabetes mellitus.

Uveitis or iritis was reported in 15 (11%) of 135 patients who were administered the 5 mg/kg maintenance dose.
