Proven relief under high pollen conditions

Just how powerful is Allegra?
Powerful enough to still provide relief even when the pollen levels are off the charts.

To prove it, we did a clinical study and placed patients in a pollen chamber where ragweed pollen levels were maintained at 4800 +/- 600 grains/cubic meter. That’s 8x higher than the normal “high” level!

Even at this high pollen level, Allegra provided clinically important relief* of allergy symptoms in 1 hour.

* Clinically important relief was defined as 3 consecutive study measurements of “slight” to “complete” relief. Symptoms include itchy watery eyes, itchy nose or throat, rhinorrhea, and sneezing. In controlled environmental studies using ragweed pollen.

When alertness really counts, pilots can count on Allegra

The FAA has, under special conditions, medically qualified pilots and air traffic controllers who are using Allegra.*

Allegra is also approved for use by pilots in the US Air Force and the US Army.

* According to FAA guidelines, non-sedating antihistamines may be used while flying after adequate individual experience has determined that the medication is well tolerated without significant side effects.

A minimum of 72 hours is required as a ground trial at initiation of therapy to ensure adequate symptom control and to exclude idiosyncratic reaction.

Not all OTC antihistamines are created equal

Unlike some antihistamines, Allegra has no warnings on the package about drowsiness or important daily activities, such as driving or operating machinery.

In clinical trials, patients taking Zyrtec reported significantly more drowsiness or fatigue than patients taking Allegra.
