What is Astelin?

Astelin (azelastine) is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Astelin nasal spray is used to treat sneezing, runny or stuffy nose, itching, and other nasal symptoms of allergies, in adults and children who are at least 5 years old.

Astelin is also used to treat ongoing nasal symptoms (runny or stuffy nose, sneezing, itching) that are not caused by allergies, in adults and children who are at least 12 years old.

Important Information

Astelin may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Before using Astelin, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by azelastine.

Drinking alcohol can increase certain side effects of azelastine. Call your doctor if your symptoms do not improve, or if they get worse while using Astelin. Stop using this medicine and call your doctor at once if you have fast or uneven heartbeats, tightness in your chest, or if you feel short of breath.

Before taking this medicine

Before using Astelin tell your doctor about all your medical conditions or allergies.

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Using Astelin while you are breast-feeding may cause your breast milk to taste bitter. If you breast-feed while using this medicine, watch for signs that your baby is not nursing as well. Talk to your doctor about the best way to feed your baby.

How should I use Astelin?

Before you use Astelin Nasal Spray for the first time, you will need to prime the bottle.

Remove the blue dust cover over the tip of the pump and the blue safety clip just under the "shoulders" of the pump.

  • Hold the bottle upright with 2 fingers on the shoulders of the spray pump unit and put your thumb on the bottom of the bottle. Press upward with your thumb and release for the pumping action. Repeat this until you see a fine mist

  • To get a fine mist you must pump the spray fast and use firm pressure against the bottom of the bottle. If you see a stream of liquid, the pump is not working correctly and you may have nasal discomfort

  • This should happen in 4 sprays or less.

Now your pump is primed and ready to use.
