The adverse effects of antiviral drugs are dose dependent and often reversible. The major side effects include influenza-like symptoms, hematologic abnormalities and neuropsychiatric symptoms. The influenza-like syndrome can be prevented by paracetamol taken at the time of the injection. Psychiatric adverse effects range from irritability to a severe depressive syndrome. Antidepressants, such as selective serotonin reuptake inhibitors, may be useful in the management. Adverse hematologic effects can occur very early during treatment. The platelet count often stabilizes rapidly, but neutropenia can deteriorate throughout treatment. In selected patients treatment with hematopoietic growth factor (filgrastim) may be useful. Ribavirin therapy may result in a dose-dependent reversible intravascular hemolytic anemia in 10% of patients. Adjunctive therapy with erythropoietin for ribavirin-induced anemia is currently under evaluation. Interferons and ribavirin are contraindicated in pregnancy. Contraception must be continued for 4 months (women) and 7 months (men) after ribavirin cessation. Lactic acidosis may be a rare complication of combination therapy in patients undergoing therapy for HIV and HCV. Any sign of mitochondrial DNA depletion syndrome calls for blood lactate measurement and, possibly, a modification of antiretroviral treatment. Lamivudine is well tolerated but the emergence of lamivudine-resistant (YMDD) HBV mutants is associated with the loss of clinical response. Adefovir dipivoxil effectively suppresses lamivudine-resistant HBV in chronic hepatitis B.
