Opticrom (cromolyn sodium) is a medication commonly used in the treatment of allergic eye conditions, such as conjunctivitis. It functions as a mast cell stabilizer, which helps to prevent the release of substances in the body that cause inflammation and allergic symptoms. Opticrom is typically administered in the form of eye drops and works by reducing itching, redness, and swelling associated with eye allergies. It is often recommended for use during allergy season or in response to known allergens. As a preventative treatment, Opticrom is most effective when used regularly during the period of allergen exposure. It is generally well-tolerated, with minimal side effects, making it a suitable option for many individuals, including those with sensitive eyes.
