Patanol is a medication used to treat the signs and symptoms of allergic conjunctivitis, which is an inflammation of the eye due to pollens that causes an allergic response. It contains the active ingredient olopatadine hydrochloride and is available as a sterile ophthalmic solution in 0.1% concentration.

Olopatadine is a medication used to treat itching, redness, and swelling in the eyes caused by allergies. It works by reducing the effects of histamine, a natural chemical in the body that is released during an allergic reaction.

Uses and Dosage

Patanol comes in the form of eye drops and is usually applied twice a day. A doctor or healthcare professional should determine the usage and dosage.

To use Patanol (Olopatadine) 0.1% Eye Drops, follow these steps:

  1. Wash your hands thoroughly with soap and water.
  2. Tilt your head back and look up.
  3. Use your finger to gently pull down your lower eyelid and create a small pocket.
  4. Hold the dropper directly over the eye and place one drop into the pocket.
  5. Close your eye and gently press on the inner corner of your eye with your finger for 1 to 2 minutes. This helps to prevent the medication from draining out of your eye and into your tear duct.
  6. If your doctor has prescribed more than one drop per eye or if you need to use the drops in both eyes, repeat the process for the other eye(s).

Use Patanol exactly as prescribed by your doctor. Do not use more or less of the medication than directed, and do not use it for longer than prescribed. If you have any questions about how to use Patanol or if you experience any side effects, contact your doctor or pharmacist for further guidance.
