Cromolyn Ophthalmic

Cromolyn ophthalmic is used to treat the symptoms of allergic conjunctivitis (a condition in which the eyes become itchy, swollen, red, and teary when they are exposed to certain substances) and keratitis (a condition that causes swelling of the cornea [tissue in the front of the eye] that causes eye redness, pain, and tearing and changes in vision) in adults and children 4 years of age and older. Cromolyn is in a class of medications called mast cell stabilizers. It works by preventing the release of substances that cause inflammation (swelling) of the eyes.

Cromolyn ophthalmic comes as a solution (liquid) to instill in the eyes. It is usually instilled into the affected eye(s) 4 to 6 times a day. Use cromolyn ophthalmic at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use cromolyn eye drops exactly as directed. Do not use them more or less of it or use it more often than prescribed by your doctor.

Your symptoms (eye itching, tearing, redness, and discharge) should improve within a few days, but may require up to 6 weeks of treatment. If your symptoms do not improve or if they worsen, call your doctor.

To instill the eye drops, follow these steps:

1. Wash your hands thoroughly with soap and water.
2. Check the dropper tip to make sure that it is not chipped or cracked.
3. Avoid touching the dropper tip against your eye or anything else; eye drops and droppers must be kept clean.
4. While tilting your head back, pull down the lower lid of your eye with your index finger to form a pocket.
5. Hold the dropper (tip down) with the other hand, as close to the eye as possible without touching it.
6. Brace the remaining fingers of that hand against your face.
7. While looking up, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. Remove your index finger from the lower eyelid.
8. Close your eye for 2 to 3 minutes and tip your head down as though looking at the floor. Try not to blink or squeeze your eyelids.
9. Place a finger on the tear duct and apply gentle pressure.
10. Wipe any excess liquid from your face with a tissue.
11. If you are to use more than one drop in the same eye, wait at least 5 minutes before instilling the next drop.
12. Replace and tighten the cap on the dropper bottle immediately after use. Do not wipe or rinse the dropper tip.
13. Wash your hands to remove any medication.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Before using cromolyn ophthalmic,

• tell your doctor and pharmacist if you are allergic to cromolyn, any other medications, or any of the ingredients in cromolyn ophthalmic. Ask your pharmacist for a list of the ingredients.
• tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following, especially other eye medications. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while using cromolyn ophthalmic, call your doctor.
• tell your doctor if you wear contact lenses. Do not wear contact lenses while you are using cromolyn eye drops.

Unless your doctor tells you otherwise, continue your normal diet.

Instill the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not instill a double dose to make up for a missed one.

Cromolyn ophthalmic may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

• stinging or burning of the eyes

Some side effects can be serious. If you experience any of these symptoms, call your doctor immediately:

• shortness of breath
• swelling
• rash

Cromolyn ophthalmic may cause other side effects. Call your doctor if you have any unusual problems while using this medication.

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from light, excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Keep all appointments with your doctor.

Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
