Usage
Dorzolamide Ophthalmic Solution should be applied as directed by your veterinarian. Please consult your veterinarian before making any changes to the prescribed dosing schedule.
For general ophthalmic use:
Wash your hands thoroughly with soap and water before and after application.
Pull your pet’s lower eyelid down gently, then apply the prescribed number of drops into the pocket between the eyelid and the eyeball.
Do NOT allow the tip of the tube to touch any surface, including your hands or your pet’s face and eyes, as this will contaminate the sterile surface.
If using multiple eye medications or products, separate dosing by at least 5 minutes. Eye drops should be used before eye ointments to allow for proper absorption.
Missed doses
Administer the dose as soon as possible. If it is almost time for the next dose, skip the missed dose and continue with the regular schedule. Do not apply two doses at once.
Storage
Store in a cool, dry place at a controlled room temperature (68 to 77°F). Keep tightly closed when not in use and out of the reach of children and pets. Store away from heat and direct sunlight. Do not store in the bathroom, near the kitchen sink, or in damp places. The medicine may break down if exposed to heat or moisture.
