Commonly reported side effects of cidofovir include: decreased creatinine clearance, hypotony of eye, increased serum creatinine, nephrotoxicity, neutropenia, and proteinuria. Other side effects include: decreased serum bicarbonate. See below for a comprehensive list of adverse effects.
Applies to cidofovir: intravenous solution
Intravenous route (Solution)
Acute renal failure resulting in dialysis or contributing to death has been reported. Use intravenous prehydration with normal saline and administration of probenecid with each cidofovir infusion to reduce nephrotoxicity. Monitor renal function within 48 hours prior to each dose and adjust dose as appropriate. Cidofovir is contraindicated in patients who are receiving other nephrotoxic agents. Neutropenia has been observed; monitor neutrophil counts during therapy. Cidofovir was carcinogenic, teratogenic, and caused hypospermia in animal studies.
Along with its needed effects, cidofovir may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Medicines like cidofovir can sometimes cause serious side effects such as blood problems and kidney problems; these are described below. Cidofovir has also been found to cause cancer in animals, and there is a chance it could cause cancer in humans as well. Discuss these possible side effects with your doctor.
Check with your doctor immediately if any of the following side effects occur while taking cidofovir:

Some side effects of cidofovir may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
Applies to cidofovir: intravenous solution
The most commonly reported adverse events include proteinuria, increased serum creatinine, neutropenia, decreased serum bicarbonate, decreased intraocular pressure, fever, and infection.
Very common (10% or more): Proteinuria (up to 88%), elevated creatinine (up to 24%), nephrotoxicity (up to 59%)
Frequency not reported: Increased BUN
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.
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. Patients should be monitored for signs and symptoms of these complications and if they develop, treatment with topical corticosteroids with or without topical cycloplegic agents may be useful.
