Summary
Trifluridine is used to treat eye infections caused by the herpes simplex virus, which is a virus that can cause sores and infections in the eyes. It helps reduce symptoms like redness, pain, and swelling in the affected eye.
Trifluridine works by inhibiting the replication of the herpes simplex virus, which means it stops the virus from multiplying. This action helps to clear the infection and reduce symptoms like redness, pain, and swelling.
Trifluridine is usually applied as an eye drop. The typical dose for adults is one drop in the affected eye every 2 hours while awake, up to 9 times a day. Once the ulcer has healed, the frequency is reduced to one drop every 4 hours while awake, up to 5 times a day.
Common side effects of trifluridine include mild eye irritation, burning, or stinging, which are usually temporary. Serious adverse effects are rare but can include severe eye irritation or vision changes. If you notice any new or worsening symptoms, contact your doctor.
Trifluridine should not be used for longer than prescribed, as prolonged use can lead to eye irritation or other complications. If you experience severe eye irritation, swelling, or vision changes, contact your doctor immediately. Do not use trifluridine if you're allergic to it or any of its ingredients.
