Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

The coadministration of ganciclovir or its prodrug, valganciclovir, with zalcitabine may result in elevated plasma concentrations of ganciclovir. In 10 asymptomatic subjects with HIV and CMV coinfection, zalcitabine (0.75 mg orally every 8 hours) increased the peak plasma concentration and area under the concentration-time curve of ganciclovir (1000 mg orally every 8 hours) by an average of 22% and 18%, respectively, although only the former was statistically significant. The mechanism is unknown. Ganciclovir had minimal effect on the pharmacokinetics of zalcitabine. This interaction is unlikely to be of clinical significance.
