Overview: Apraclonidine is an eye drop used to lower pressure inside the eye. An over-the-counter (OTC) form is also available to relieve eye redness. The strength of medicine is different between the OTC and the prescription products. Do not use the prescription product for eye redness or the OTC product to lower eye pressure. The most common side effects are dizziness, sleepiness, and dry mouth. Before using apraclonidine, tell your health care provider about any health conditions and any medicines you use or have recently taken. Talk with your health care provider right away if you have symptoms of an allergic reaction.
Uses
What is apraclonidine used for?
Apraclonidine is commonly used for lowering pressure inside the eye (intraocular pressure). It is also used to control or prevent increased eye pressure after certain eye surgeries for glaucoma or cataracts.
A lower strength (0.125%) over-the-counter (OTC) form of apraclonidine is commonly used to relieve redness of the eye caused by mild eye irritation.
Apraclonidine may also be used for other conditions as determined by your health care provider.
How does apraclonidine work (mechanism of action)?
High pressure inside the eye can lead to nerve damage and vision loss. Prescription apraclonidine works by reducing the amount of fluid in the eye, which helps to lower eye pressure.
OTC apraclonidine helps relieve redness by narrowing or constricting the tiny blood vessels in the eye. This reduces blood flow to the surface of the eye, which makes the whites of your eyes look less red.
