What is Flarex?
Fluorometholone is a steroid medicine. It prevents the release of substances in the body that cause inflammation.
Flarex (for the eyes) is used to treat eye swelling caused by infections, injury, surgery, or other conditions.
Flarex may also be used for purposes not listed in this medication guide.
You should not use this medicine if you have any type of infection, especially a fungal or viral eye infection (such as ocular herpes), tuberculosis, or an untreated infection such as chickenpox in your eye or elsewhere.
Before taking this medicine
You should not use this medicine if you are allergic to fluorometholone or other steroid medications, or if you have any type of infection, especially:
a fungal eye infection;
any type of viral eye infection, such as ocular herpes;
an untreated infection in your eye or elsewhere, including chickenpox.
To make sure Flarex is safe for you, tell your doctor if you have:
a history of cataracts; or
a history of glaucoma or increased pressure inside your eyes.
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether Flarex passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Flarex should not be given to a child younger than 2 years old.
How should I use Flarex?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Do not use this medicine while wearing contact lenses. Flarex may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using this medicine before putting in your contact lenses.
Wash your hands before using eye medication.
Shake the eye drops well just before each use.
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 with the tip down. Look up and away from the dropper and squeeze out a drop.
Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops.
Wait at least 10 minutes before using any other eye drops your doctor has prescribed.
Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.
To apply the ointment:
Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the ointment tube with the tip pointing toward this pocket. Look up and away from the tip.
Squeeze out a ribbon of ointment into the lower eyelid pocket without touching the tip of the tube to your eye. Blink your eye gently and then keep it closed for 1 or 2 minutes.
Use a tissue to wipe excess ointment from your eyelashes.
After opening your eyes, you may have blurred vision for a short time. Avoid driving or doing anything that requires you to be able to see clearly.
Do not touch the tip of the eye dropper or ointment tube or place it directly on your eye. A contaminated applicator tip can infect your eye, which could lead to serious vision problems.
Call your doctor if your symptoms do not improve after 2 days of treatment with Flarex.
If you use Flarex for 10 days or longer, you may need frequent eye tests at your doctor's office.
Store at room temperature away from moisture and heat. Do not freeze. Store eye drops with the bottle upright. Keep the tube or bottle tightly closed when not in use.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
An overdose of Flarex is not expected to be dangerous. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.
What should I avoid while using Flarex?
Do not wear any contact lens that has not been approved by your doctor.
Do not share this medication with another person, even if they have the same symptoms you have.
Do not use other eye medications unless your doctor tells you to.
Fluorometholone can cause side effects that may impair your vision. Be careful if you drive or do anything that requires you to see clearly.

What other drugs will affect Flarex?
Tell your doctor about all your current medicines and any you start or stop using, especially an oral, nasal, inhaled, or injectable steroid medicine.

Tell each of your healthcare providers about all medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.
