Uses for atropine sulfate
Atropine sulfate eye drops is used to dilate the pupil before eye exams. It is also used to treat an eye condition called amblyopia (lazy eyes) and other eye conditions (eg, cycloplegia). Atropine sulfate works by blocking the chemical acetylcholine, which relaxes the ciliary muscle of the eye and causes the pupil to dilate.
Atropine sulfate is available only with your doctor's prescription.

Proper use of atropine sulfate
Your eye doctor will tell you how much of atropine sulfate to use and how often. Do not use more medicine or use it more often than your doctor tells you to. Atropine sulfate is not for long-term use.
To use the eye drops:
- First, wash your hands. Tilt the head back and, pressing your finger gently on the skin just beneath the lower eyelid, pull the lower eyelid away from the eye to make a space. Drop the medicine into this space. Let go of the eyelid and gently close the eyes. Do not blink. Keep the eyes closed for 1 or 2 minutes to allow the medicine to be absorbed by the eye.
- Immediately after using the eye drops, wash your hands to remove any medicine that may be on them.
- If you think you did not get the drop of medicine into your eye properly, use another drop.
- To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, always keep the container tightly closed.
The dose of atropine sulfate will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of atropine sulfate. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
