What is the typical dosing per day for topical Ganciclovir (Zirgan)?

Explanation:
Ganciclovir ophthalmic gel needs to maintain antiviral levels on the corneal surface during the active healing phase, and tear turnover clears the drug quickly. Because of this, the dosing schedule is five instillations per day to keep inhibitory concentrations consistently in contact with the infected tissue as the virus replicates. This frequent dosing supports rapid epithelial healing, with a plan to taper once healing occurs.
