Alrex (generic name: loteprednol) is a
corticosteroid medication used to treat
seasonal allergic conjunctivitis, an inflammation of the conjunctiva caused by allergens. It works by suppressing the release of substances in the body that cause inflammation, such as prostaglandins and leukotrienes.
Alrex may also be used
off-label for mild cases of uveitis, but only under a doctor’s supervision. As a topical eye drop, it targets the affected area directly, reducing swelling, itching, and redness. This drug is part of the
ophthalmic corticosteroid class, offering a localized treatment option with minimal systemic effects.
Dosage
The typical dosage for Alrex is one to two drops in the affected eye(s) four times daily. Shake the bottle well before use. To maintain its efficacy, the medication must be administered at evenly spaced intervals. If a dose is missed, administer it as soon as remembered unless it is close to the next scheduled dose. In such cases, skip the missed dose and resume the regular schedule. Do not double-dose to make up for any that were missed.
Storage
Store Alrex at a controlled room temperature between 15°-25°C (59°-77°F). Keep the bottle tightly closed when not in use to avoid contamination. Do not freeze. Protect the medication from excessive heat and direct sunlight. Always check the expiration date before use and dispose of the product if it has expired. Get more advice about safe drug storage here.
