The eye drops are available by prescription only and are typically applied to the affected eye(s) four times daily. Side effects that may occur include eye discharge, dry eyes, and blurred vision.

How Does Alrex Work?

Alrex belongs to a group of allergy medications known as corticosteroids, or simply "steroids" for short. Steroids can have many different effects in the body, including anti-inflammatory effects. Steroids decrease inflammation by limiting the body's ability to produce an immune system reaction. They can be very effective for treating conditions such as allergies. However, long-term use of steroids can cause bothersome and sometimes serious side effects, and this limits the usefulness of many steroids. Because Alrex is an eye drop, its effects are generally limited to the eye. This helps prevent many of the long-term side effects of steroids.
