How does the Jetrea medication work? What will it do for me?
This medication belongs to the class of medications called proteolytic enzymes. It is used to treat an eye condition called symptomatic vitreomacular adhesion or VMA. VMA is caused by the jelly-like material (vitreous gel) in the eye sticking to the inner surface at the back of the eye (the macula). This causes reduced vision. If the condition is not treated, it may result in a hole in the macula, causing permanent vision damage. Ocriplamsin works by separating the vitreous gel from the macula.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications.

What other drugs could interact with the Jetrea medication?
Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Tell your doctor if you have had an injection of any medicine into the eye recently. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
