Pink eye caused by allergies can be relieved with ophthlamic azelastine. The drug azelastine belongs to the antihistamine drug class. Histamine, a chemical in the body that causes allergy reactions, is blocked in order for it to function.

Ophthalmic azelastine is available as a liquid solution that is injected into the eye. Usually, it is injected into the afflicted eye(s) twice daily. Use azelastine at roughly the same time each day to aid in memory. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. As directed, take azelastine. Use it only as directed by your doctor, neither more nor less often.

Follow these steps to administer the eye drops:

1. Use soap and water to thoroughly wash your hands.
2. Make sure the dropper tip is not cracked or chipped by inspecting it.
3. Eye drops and droppers must be kept clean; avoid contacting the dropper tip to your eye or anything else.
4. Pull your lower eyelid down to create a pocket with your index finger while cocking your head back.
5. With your other hand, place the dropper as near to your eye as you can without touching it, tip down.
6. Place the hand’s remaining fingers to your face.
7. Squeeze the dropper gently while looking up so that a single drop falls into the lower eyelid’s pocket. Your index finger should be taken off the lower eyelid.
8. Tip your head down so that you are looking at the floor while closing your eyes for two to three minutes. Avoid blinking or squeezing your eyelids.
9. Give the tear duct a gentle squeeze with your finger.
10. Use a tissue to remove any extra liquid from your face.
11. Wait at least 5 minutes before administering the subsequent drop if you need to use more than one in the same eye.
12. Replace and secure the dropper bottle’s cap. Never rinse or clean the dropper tip.
13. To get rid of any medication, wash your hands.

Ask your doctor or pharmacist for more details if you believe this medication should be used for something else.

Before using azelastine eye drops,

• If you have a reaction to azelastine or any other medication, tell your doctor and pharmacist right away.
• Inform your physician and pharmacist about all prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are taking.
• Inform your doctor if you are expecting, intend to get pregnant, or are nursing a baby. Call your doctor if you become pregnant while taking azelastine.
• If your eye(s) are red, you should be aware that you shouldn’t wear contact lenses. If you wear contact lenses and your eye is not red, you should be aware that azelastine solution contains benzalkonium chloride, which soft contact lenses can absorb. Before administering azelastine, take out your contact lenses, and then replace them after waiting 10 minutes.

Keep eating normally unless your doctor instructs you otherwise.

The missed dose should be administered as soon as you remember. If the next dose is soon due, skip the missed one and carry on with your regular dosing plan. To make up for a missed dose, do not administer a second dose.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
