How should I use lotilaner ophthalmic?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Lotilaner ophthalmic is used twice per day, about 12 hours apart, for 6 weeks.

Tell your doctor if you have a planned eye surgery.

Wash your hands before using eye medication.

Do not use while wearing soft contact lenses. A preservative in lotilaner ophthalmic could permanently stain the lenses. Wait at least 15 minutes before inserting your contact lenses.

To apply the eye drops: Pull down your lower eyelid to create a small pocket and squeeze a drop into this pocket. Close your eyes for 1 or 2 minutes.

Use only the prescribed number of drops.

Wait at least 5 minutes before using any other eye drops.

Do not touch the dropper tip or place it directly on your eye. A contaminated dropper can infect your eye and lead to serious vision problems.
