Prescription only Patanol Eye Drops (olopatadine 0.1%) have been discontinued in the United States. In February 2020 Patanol was rebranded Pataday Twice Daily Relief (olopatadine 0.1%) and is now available over-the-counter (OTC).

What is Patanol?

Patanol (olopatadine) is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of itching or watery eyes.

Patanol eye drops are used to treat eye itching caused by allergies.

Patanol may also be used for purposes not listed in this medication guide.

Warnings

Before using Patanol, tell your doctor if you have any type of infection in your eye.

Do not use the eye drops while you are wearing contact lenses. The eyes drops may contain a preservative that can be absorbed by soft contact lenses. Wait at least 10 minutes after using Patanol before putting your contact lenses in.

Avoid wearing contact lenses while your eyes are red or irritated.

Do not allow the Patanol dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.

Do not use the eye drops if the liquid has changed colors or has particles in it.

Stop using Patanol and call your doctor at once if you have severe redness, swelling, burning, stinging, drainage, crusting, or other irritation when using the eye drops.

Before taking this medicine

You should not use Patanol if you are allergic to olopatadine.

Ask a doctor or pharmacist if Patanol is safe to use if you have any type of eye infection.

Tell your doctor if you are pregnant or breastfeeding.

Patanol eye drops are not approved for use by anyone younger than 2 years old.

How should I use Patanol?

Use Patanol eye drops exactly as directed on the label, or as prescribed by your doctor.

Do not use while wearing soft contact lenses. A preservative in this medicine could permanently stain the lenses. Use the medicine at least 15 minutes before inserting your contact lenses.

Wash your hands before using eye medication.

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 and squeeze a drop into this pocket. Close your eyes for 1 or 2 minutes.

  • Wait at least 10 minutes before using any other eye drops your doctor has prescribed.

Use only the number of drops recommended on the medicine label.

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 looks cloudy or has changed colors.

Store at room temperature away from moisture and heat. Do not freeze. Keep the bottle tightly closed when not in use.
