What Is Isopto Carpine Used For?

Isopto Carpine is an eye drop medication that helps treat glaucoma, a serious eye condition that can damage your vision if left untreated.

Primary Uses

Isopto Carpine is used to treat glaucoma, an eye condition that damages the optic nerve. Glaucoma is usually caused by a buildup of fluid in the eye, often associated with increased eye pressure that damages the optic nerve.

How It Works

Isopto Carpine eye drops help lower increased eye pressure by increasing the amount of fluid that drains from the eye, reducing the pressure that can damage your optic nerve.

How to Take Isopto Carpine

Follow your doctor’s instructions carefully when using these eye drops. Proper technique is important for the medication to work effectively.

Dosage Instructions

Use 1-2 drops in the affected eye(s) 3-4 times daily. Remove contact lenses before use and wait 15 minutes before putting them back in. Wash hands thoroughly, shake bottle well, tilt head back, pull down lower eyelid to form a pouch, place tip close to eye without touching, release one drop, close eye gently, and press finger against inside corner of eye for 2 minutes. Wait at least 5 minutes before using other eye drops. Discard 4 weeks after opening.

What If You Miss a Dose?

If you miss a dose, use it as soon as you remember, then return to your normal schedule. If it’s almost time for your next dose, skip the missed dose and continue with your regular timing.

Important: Do not take a double dose to make up for a missed dose. Do not touch the dropper tip to any surface to avoid contamination.
