How should I use trifluridine ophthalmic?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
The initial dose of this medicine is 1 drop into the affected eye every 2 hours while you are awake. Once your condition improves, you may need to keep using the medication 4 times daily for another 7 days. Follow your doctor's dosing instructions very carefully.
You may need eye exams to help your doctor determine how long to treat you with trifluridine. In most cases, you should not use this medicine for longer than 21 days.
Wash your hands before using the eye drops.
To apply the eye drops:
Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
Use only the number of drops your doctor has prescribed.
Wait at least 10 minutes before using any other eye drops your doctor has prescribed.
Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.
Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.
Call your doctor if your symptoms do not improve after 7 days of treatment with trifluridine ophthalmic.
Do not use trifluridine to treat any eye condition that has not been checked by your doctor. Trifluridine will not treat an infection caused by fungus or bacteria.
Store in the refrigerator, do not freeze. Keep the bottle tightly closed when not in use.
