Contact your doctor immediately if you notice any decrease in vision or an increase in "floaters" in your visual field. Rarely, carbachol ophthalmic may cause retinal detachment. Retinal detachment can lead to blind spots, floaters in your visual field, and even blindness. Your doctor will want to check your retina before you use this medicine to determine if you have an increased risk of retinal detachment.

Do not touch the dropper to any surface, including the eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in the eye.

Apply light pressure to the inside corner of the eye (near the nose) after each drop to prevent the fluid from draining down the tear duct.

Use caution when driving, operating machinery, or performing other hazardous activities. Carbachol ophthalmic may cause decreased vision at night. If you experience decreased vision, avoid these activities.

Carbachol ophthalmic reduces the pressure in the eye by increasing the amount of fluid that drains from the eye. Carbachol ophthalmic also causes the pupil to become smaller and reduces its response to light or dark conditions.

Carbachol ophthalmic is used to treat glaucoma by lowering the pressure inside the eye.

Carbachol ophthalmic may also be used for purposes other than those listed in this medication guide.

Rarely, carbachol ophthalmic may cause retinal detachment. Tell your doctor if you have any type of retinal disease, if you have had a retinal tear, if you are nearsighted, or if you have had cataract surgery. These conditions may increase the risk of retinal detachment.

If you wear contact lenses, remove them before applying carbachol ophthalmic. Ask your doctor if contact lenses can be reinserted after application of the medication. Carbachol ophthalmic may contain a preservative (benzalkonium chloride), which may cause discoloration of contact lenses.

To apply the eye drops:

• Tilt the head back slightly and pull down on the lower eyelid. Position the dropper above the eye. Look up and away from the dropper. Squeeze out a drop and close the eye. Apply gentle pressure to the inside corner of the eye (near the nose) for about 1 minute to prevent the liquid from draining down the tear duct. If you are using more than 1 drop in the same eye, repeat the process with about 5 minutes between drops. Repeat the process in the other eye if needed.

Do not touch the dropper to any surface, including the eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in the eye.

Do not use any eye drop that is discolored or has particles in it.

Seek emergency medical attention if an overdose is suspected or if the drops have been ingested.
