Patanase (olopatadine) is a nasal spray for the treatment of the symptoms of seasonal allergic rhinitis (seasonal allergies or hay fever) in patients ages 6 and older.

How are Patanase and olopatadine prescribed?
Patanase and generic olopatadine nasal sprays come in 30.5g containers, with 240 metered sprays per container. Each dose (spray) contains 665 mcg of the active ingredient, olopatadine.

The usual dose for adults ages 12 and older is 2 sprays in each nostril twice daily. For children ages 6 – 11, the usual dose is 1 spray in each nostril twice daily.

What kind of allergy medication is olopatadine?
Olopatadine is an antihistamine. Antihistamines work by blocking the release a substance known as histamine which can cause swelling, inflammation, or in this case the allergy symptoms associated with allergic rhinitis. This includes a stuffy, runny, or itchy nose, and sneezing.

What are the most common side effects?

The most common side effects of olopatadine include a bad or bitter taste in the mouth, headache, nose bleed.

Olopatadine can also make you feel sleepy—you should be cautious and not operate heavy machinery, drive, or participate in dangerous activities until you know how it will affect you.

Are there any similar alternative medciations to olopatadine?

Yes. Astepro and Astelin (both with the active ingredient azelastine) are also antihistamine nasal sprays.

There may be if your children need a nasal spray for allergies. Astelin is indicated for use in patients as young as 5 years old, while Astepro and Patanase aren’t recommended for anyone under the age of 6.

Additionally, Patanase (olopatadine) and Astelin (azelastine) now have generics available, while Astepro is still brand-name-only.
