Warnings

You should not be treated with Dextenza if you:

• are allergic to dexamethasone, or 
• have an infection in or around your eye.

Dexamethasone can worsen or reactivate an eye infection you already have or have recently had (including herpes infection of the eyes).

Before using this medicine

Tell your doctor if you have ever had:

• glaucoma;
• a detached retina;
• cataracts (unless you are receiving this medicine as part of cataract surgery); or
• herpes infection of the eyes.

Tell your doctor if you are pregnant or breastfeeding.

How is Dextenza given?

Dextenza will be inserted into your eyelid by a healthcare professional in a clinic setting.

The doctor will use a medicine to numb your eye before inserting the implant.

After this medicine has been given, you will be watched closely for any swelling, inflammation, or increased pressure in your eye.

You may need medication or other treatments to keep the increased pressure in your eye from getting too high. Follow your doctor's instructions.
