Side Effects by Body System

General

In phase 3 clinical trials, ganciclovir was discontinued due to adverse effects in 9% of patients receiving maintenance treatment for CMV retinitis. Ganciclovir was discontinued 19.5% of AIDS patients receiving CMV prophylaxis due to adverse events, new or worsening intercurrent disease, or laboratory abnormalities (compared to 16% receiving placebo).

Hematologic

Bone marrow suppression is dose-related and usually occurs before a total dose of 200 mg/kg is reached. Sargramostim (GM-CSF) or filgrastim (G-CSF) have been used for the management of neutropenia due to ganciclovir.

Hematologic side effects have included neutropenia, anemia, and thrombocytopenia and are the major toxicity of ganciclovir. Leukopenia, pancytopenia, hemolytic anemia, hemolytic uremic syndrome, pure red blood cell aplasia, eosinophilia, and neutrophil dysplasia (with evidence of bone marrow hypoplasia) have also been reported. Coagulation disorder has been reported in pediatric patients.

Gastrointestinal

Gastrointestinal side effects have included diarrhea (41% to 48%), anorexia (14% to 19%), vomiting (13% to 14%), nausea, flatulence, abdominal pain, aphthous stomatitis, constipation, dyspepsia, eructation, intestinal ulceration, gastrointestinal perforation, pancreatitis, dysphasia, and cholelithiasis.

Renal

Renal side effects have included increased serum creatinine, kidney failure, abnormal kidney function, and renal tubular disorder. Abnormal kidney function has also been reported in pediatric patients.

Genitourinary

Genitourinary side effects have included urinary frequency, infertility, and testicular hypotrophy.

Hypersensitivity

Hypersensitivity side effects have included allergic reaction, anaphylactic reaction, exfoliative dermatitis, and Stevens-Johnson syndrome.

Ocular

Ocular side effects have included retinal detachment (8% to 11%) in patients with CMV retinitis, both before and after initiation of treatment. Abnormal vision, dry eyes, vitreous disorder, cataracts, and oculomotor nerve paralysis have also been reported.

Cardiovascular

Cases of ventricular tachycardia associated with ganciclovir infusions in patients with AIDS have been reported, although it is known that HIV infection is associated with myocarditis, decreased left ventricular function, and in some cases, nonsustained ventricular tachycardia.

Cardiovascular side effects have included hypertension, phlebitis, edema, vasodilatation, cardiac arrest, cardiac conduction abnormality, vasculitis, stroke, torsades de pointes, and ventricular tachycardia. Hypertension has been reported in pediatric patients.

Dermatologic

Dermatologic side effects have included pruritus (5% to 10%), alopecia, and dry skin. Interstitial granulomatous drug reaction has been reported in at least one patient.

Hepatic

Rare cases of hepatitis associated with ganciclovir have been reported, but in most cases, other potentially hepatotoxic drugs were coadministered.

Hepatic side effects have included increased SGOT and SGPT, cholestasis, hepatic failure, and hepatitis.

Nervous system

Nervous system side effects have included neuropathy (8% to 21%), abnormal dreams, anxiety, confusion, depression, dizziness, dry mouth, insomnia, seizures, somnolence, abnormal thinking, tremor, agitation, delirium, dysesthesia, encephalopathy, extrapyramidal reaction, facial palsy, hallucinations, intracranial hypertension, irritability, loss of memory, and myelopathy.
