What is Patanase Nasal Spray or generic Olopatadine HCL?

Patanase Nasal Spray, or generic Olopatadine HCL, is a steroid-free prescription antihistamine. Also known as a selective H1-receptor antagonist, it blocks histamine receptors so histamine messages cannot be received.

Patanase Nasal Spray or Patanase generic may be prescribed to adults and children aged six years and older who deal with seasonal allergic rhinitis, better known as hay fever. This nasal spray can reduce symptoms of stuffy, runny, or itchy nose, and sneezing most commonly caused by pollen present in the spring and summer months and even into early fall.

The generic alternative is not manufactured by the company that makes the brand product.

Conditions treated by Patanase Nasal Spray or generic Olopatadine HCL

Patanase Nasal Spray or generic Olopatadine HCL may be prescribed to people dealing with seasonal allergic rhinitis, also known as hay fever. For many people, inhaling pollen triggers the immune system to produce histamine in order to flush out the intruding substance. Tiny capillaries become more permeable and white blood cells move into them, which creates the fluid that leads to an itchy, runny nose, watery eyes, and sneezing. Patanase Nasal Spray doesn't stop the production of histamine, but rather blocks the effects of histamine so symptoms lessen in as little as 30 minutes.

Patanase Nasal Spray or generic Olopatadine HCL FAQs

What is the proper dosage of Patanase Nasal Spray or generic Olopatadine HCL?

The proper Patanase Nasal Spray dose depends on the patient, so it's important to carefully follow your doctor's instructions. The number of doses you take each day, as well as the time between each dose is also dependent on the individual. For adults and children 12 years and older, the typical dose is two sprays in each nostril twice daily. For children between 6 and 11 years old, that dose decreases to one spray per nostril twice daily. If you miss a dose, take it as soon as possible unless it is close to the time for your next dose (in which case you can skip the missed dose). Do not double dose.
