Indications 

Patanol is an ophthalmic medication prescribed for managing the signs and symptoms of allergic conjunctivitis, such as inflammation, itching, watering, and burning in the eyes. 

Classified as an antihistamine, Patanol works by lowering the levels of histamine, a naturally occurring chemical in the body that triggers allergic reactions. 

Uses and Dosage 

Before using Patanol, and with each prescription refill, carefully review its medication guide and patient information leaflet. Consult your physician or pharmacist if you have any queries or uncertainties. 

Patanol is for ophthalmic use only and should not be injected or taken orally. 

The usual dosage of Patanol is one drop in each affected eye, twice daily, with a 6 to 8 -hour gap between doses. 

To properly administer this eye drop, follow these steps: 

1. Begin by washing your hands thoroughly. 
2. To prevent contamination, avoid touching the dropper tip or allowing it to come into contact with your eye or any other surface. 
3. If wearing contact lenses, remove them before applying the eye drops. Wait at least 10 minutes before putting them back. 
4. Tilt your head back and look upward. Use your fingers to gently pull down the lower eyelid, creating a small pouch. 
5. Position the dropper above the eye and carefully place one drop into the pouch. 
6. Look downward and gently close your eyes. Place one finger on your tear duct and apply gentle pressure for 1 to 2 minutes to prevent the medication from draining out. 
7. Avoid blinking or rubbing your eye during this time. 
8. If instructed to use the medication in both eyes, repeat the above steps for the other eye. 
9. Do not rinse the dropper. Replace the dropper cap securely after each use. 

Allow at least 5 minutes between applying different eye medications, such as drops or ointments. Prioritize using eye drops before eye ointments to ensure effective absorption.  

For optimal results, use Patanol at a regular time daily. Administer it exactly as directed; do not alter the number of drops or use it more frequently than prescribed by your doctor.
