This is an eye drop containing trifluridine that is used to fight viral infections of the eye, such as in herpetic eye disease. While effective, the drop can be a little harsh on the ocular surface with prolonged use.  Sadly, there aren’t many antiviral alternatives available in this country. Zirgan is a new antiviral ointment that may be better tolerated as it requires less frequent dosing.
