Prescription RequiredQuick Facts
What Is Enidin Used For?
Enidin eye drops contain brimonidine tartrate and are specifically designed to treat eye conditions involving increased pressure.
Primary Uses
Enidin is used to lower raised pressure in the eye(s) and to treat glaucoma. It can be used alone or together with other eye drops or medicines to control eye pressure.
How It Works
Enidin works by decreasing the fluid produced in the eye and helping the flow of fluid out of the eye chamber, which reduces pressure. It belongs to a family of medicines called alpha-adrenergic agonists.
Good to know: Although Enidin helps control your glaucoma, it does not cure it. Continued use as prescribed is important for maintaining eye health.
How to Take Enidin
Enidin eye drops should be used exactly as prescribed by your doctor. Proper technique is important for effectiveness and safety.
Dosage Instructions
The usual dosage is one drop in the affected eye(s) two times a day, approximately every 12 hours. Use at the same time each day for best results. If using other eye drops, wait at least 5 to 10 minutes after using Enidin before applying other drops. Remove soft contact lenses before use and wait 15 minutes before replacing them.
What If You Miss a Dose?
If you forget a dose and it’s almost time for your next dose, skip the missed dose and continue with your regular schedule. If you remember soon after missing a dose, use it as soon as you remember, then return to your normal schedule.
Important: Never take a double dose to make up for a missed dose. Do not touch the dropper tip to your eye, eyelid, or any surface to avoid contamination.
