Works Fast and Long Lasting

[This review was collected as part of a promotion.] This is the only thing that works for my allergies! Doesn't make me tired and sleepy. Works quickly and it only takes one tablet to last for 24 hour allergy relief! Allegra is the best for indoor/outdoor allergies!

Great allergy relief

[This review was collected as part of a promotion.] I have terrible allergies all year round. I have tried just about every allergy medicine on the market and this one seems to be most effective. I took it at night before bed since I typically wake up all stuffed up. But after taking this, I wake up refreshed and almost normal! I still have some congestion after taking this but that’s probably due to year round congestion that seems to never go away for me.

Allegra

[This review was collected as part of a promotion.] Just one pill a day give me full-day allergy control. I appreciate the once-a-day simplicity. It cures my symptoms & doesn’t make me drowsy. I prefer it over all other products out there. It’s a must have for both me and my family.

All day is the way

[This review was collected as part of a promotion.] These seem to really do the all day trick with my summer allergy nonsense! My itchy eyes are maintained all day after taking one of these tablets. I did not experience and negative side effects nor did I experience any drowsiness. Pill is easy to take and pack is easy to open and travel with. Also easy to store. I wish ingredients were more naturally based and I wish the price point was a little more fair.

Sweet Relief!

[This review was collected as part of a promotion.] I struggle with allergies and have never tried a simple OTC medication to help with it and I was SHOCKED at the difference I felt and it was almost immediate. I absolutely would recommend this to my close friends and family.

Allegra works

[This review was collected as part of a promotion.] Allegra 24Hr has worked amazingly great for my allergies. Living in the south during pollen season is the worst for anyone with allergies. Allegra has helped take the edge off and makes it feel like I can function again.

Great for 6 hrs not 24.

[This review was collected as part of a promotion.] Works really well for about 6 hours. It to me isn't worth paying more for a product that does not last 24 hours like it claims. I was very excited when the sniffling and battery eyes went away. Then greatly let down when it only lasted 6 or so hours.

Solved

[This review was collected as part of a promotion.] I’m always satisfied with products from this brand. I have awful seasonal allergies and this was very effective for me. Packaging is eye catching making it easy to find in aisles and aisles of various medications.

Very Effective

[This review was collected as part of a promotion.] I suffer from allergies in the Spring and Summer, it’s unbearable. I have found that Allegra really works the best at helping with the sneezing and constant eye itching. The non-drowsy pill is perfect and the best part is that it lasts all day so I don’t have to keep taking pills throughout the day. Easy to swallow and not too chalky. Allegra for the win!
