What is demecarium bromide ophthalmic (Humorsol)?

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

Demecarium bromide ophthalmic is used to treat glaucoma by lowering the pressure inside the eye. Demecarium bromide ophthalmic is also used for other conditions that require increased fluid outflow from the eye, after surgical iridectomy, and for certain eye disorders involving eye accommodation (focusing).

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

What are the possible side effects of demecarium bromide ophthalmic (Humorsol)?

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

If you experience any of the following serious side effects, stop using demecarium bromide ophthalmic and seek emergency medical attention or contact your doctor immediately:

• an allergic reaction (shortness of breath; closing of the throat; swelling of the lips, face, or tongue; or hives);
• abdominal cramps or diarrhea;
• watering mouth;
• excessive sweating;
• urinary incontinence;
• muscle weakness;
• difficulty breathing; or
• an irregular heart beat.

Other, less serious side effects may be more likely to occur. Continue to use demecarium bromide ophthalmic and talk to your doctor if you experience

• burning, stinging, red, or tearing eyes;
• eyelid muscle twitches;
• headache or brow ache; or
• decreased vision in poor light.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

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 application to prevent the medicine from draining down the tear duct.

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