Why is this medication prescribed?

Cromolyn ophthalmic is prescribed primarily for the treatment of allergic conjunctivitis. Allergic conjunctivitis is an inflammatory condition of the conjunctiva, which is the thin membrane covering the white part of the eye and lining the inside of the eyelids. This condition is caused by an allergic reaction to allergens such as pollen, pet dander, dust mites, or certain medications.

Cromolyn ophthalmic works by stabilizing mast cells in the eyes, which are cells involved in allergic reactions. By stabilizing these cells, Cromolyn prevents the release of histamines and other substances that cause inflammation, itching, redness, swelling, and watering of the eyes associated with allergic conjunctivitis.

How should this medicine be used?

Here’s how Cromolyn ophthalmic should typically be used:

• Dosage: Follow your doctor’s instructions carefully. Cromolyn ophthalmic is usually applied as eye drops. The usual dose is one drop in each affected eye four to six times a day at regular intervals.
• Application: Wash your hands thoroughly before using the eye drops. Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
• Administering the Drops: Hold the dropper directly over your eye and place one drop into the pocket you created. Blink gently and keep your eyes closed for 1-2 minutes to allow the medication to be absorbed. If you are using drops in both eyes, repeat the process for the other eye.
• Precautions: Do not touch the tip of the dropper to your eye or any other surface to avoid contamination. Replace the cap after each use. If you wear contact lenses, remove them before applying Cromolyn eye drops and wait at least 10 minutes before reinserting them.
• Consistency: Use Cromolyn ophthalmic regularly as prescribed, even if you do not have symptoms. It works best when there is a constant amount in the eyes.
• Duration: Continue using Cromolyn ophthalmic for the full prescribed duration, even if your symptoms improve. Do not stop using it without consulting your doctor.

Always consult your doctor or pharmacist if you have any questions or concerns about how to use Cromolyn ophthalmic properly. They can provide specific guidance based on your condition and medical history.
