This medication is used alone or with other medications to treat certain types of glaucoma and other eye conditions (e.g., accommodative esotropia, synechial formation). It is also used to test for certain eye conditions (e.g., accommodative esotropia). It works by causing the pupil to shrink, decreasing the amount of fluid within the eye, and affecting certain eye muscles.
Follow all directions supplied by the manufacturer for mixing the eye drops.
To apply eye drops, wash your hands first. To avoid contamination, be careful not to touch the dropper to any surface or let it touch your eye.
Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch. Let go of the eyelid and gently close your eyes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure for 1 to 2 minutes. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Repeat these steps for your other eye if so directed or if your dose is for more than 1 drop.
Remove extra solution around the eye with a tissue, and wash your hands to remove any medicine that may be on them. Do not rinse the dropper. Replace the dropper cap after each use.
If you are using another kind of eye medication (e.g., drops or ointments), wait at least 5 minutes before using the other medication. Use eye drops before ointments to allow the eye drops to enter the eye.
The dosage is based on your medical condition and response to therapy. Do not increase your dose or use more frequently than directed by your doctor. Doing so may increase the risk for serious side effects.
Temporary irritation/burning/stinging of the eye, temporary blurred vision, eyelid muscle twitching, poor vision in dim light, headache, or brow ache may occur. If any of these effects persist or worsen, contact your doctor or pharmacist promptly. (See also Precautions section.)
Tell your doctor immediately if any of these unlikely but serious side effects occur: eye pain, flushing, diarrhea, nausea, irregular heartbeat, stomach/abdominal pain or cramps, increased saliva, increased urination, unusual sweating, vision changes.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
