How does Jetrea 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.

How should I use Jetrea?

The recommended dose is 0.125 mg (0.1 mL of the diluted solution) injected into the vitreous gel of the eye, by a qualified health care professional. It is always given under the supervision of a doctor in a hospital or similar setting with access to sterile equipment for preparation and injection.

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

Are there any other precautions or warnings for Jetrea?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Eye problems: Ocriplasmin can cause eye problems such as infection of the inside part of the eye, pain or redness, detachment or tear of the retina, or increased pressure inside the eyes. Contact your doctor immediately if you experience eye pain, increased eye discomfort, worsening eye redness, blurred or reduced vision, increased sensitivity of the eyes to light, or an increase in the number of small particles in your vision.

Vision problems: This medication can cause temporary vision problems that may affect your ability to drive or operate machines. If you experience vision problems, do not drive or operate machines until your vision returns to normal.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: It is not known if ocriplasmin passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

What other drugs could interact with Jetrea?

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.
