For me relief doesn't last 24 hours but it does get me through the day so I am not constantly sneezing at work.

without it I would be teary eyed and have a runny nose and cough. Easy to take and reduces congestion

Works great to relieve allergy symptoms. Non drowsy, easy to swallow, good packaging, good potency, great value for your money, light weight. Easy to store or take with you. Well designed. Highly recommend!

When the weather is friendly I give one to my daughter and it relieves her allergy quantity, the effect has a duration of at least 8 hours. The size of the pill is perfect to take.

These are more than double the strength as the original, but work for all day relief. These are easy to take. The bottle is a smaller sized bottle which is easy to tote or take on trips. If you have allergies I highly recommend these

What I like is that they don't make me feel drowsy, so I can take them in the morning and still function normally, even on busy days. They kick in pretty quickly for me, usually within an hour, and I can get through the day without constantly sneezing or dealing with itchy, watery eyes. The tablets are small enough to swallow easily, and I don't notice any weird aftertaste. They seem to work consistently whether my allergies are flaring from pollen in the spring or dust at home. I still need to pair them with a nasal spray sometimes for full relief, but on their own, they make a huge difference. They're not the most exciting product, but when your allergies are miserable, you just want something that works, and these do. It's a dependable fix that I trust to get me through high-allergy days without knocking me out.

I use this product often, but if I'm going somewhere where I know that my allergies will really bother me then it doesn't work as well, but for general allergies around the house and at work then it does the job and especially if I forget to take it because it's 24 hours, It works fine.

[This review was collected as part of a promotion.] I’ve struggled with seasonal allergies for years—runny nose, itchy eyes, sneezing fits, the works. I’ve tried a bunch of over-the-counter meds, but Allegra 24 Hour has honestly worked the best for me. What I really appreciate is that it actually lasts all day. I just take one in the morning, and I’m good to go. Plus, it doesn’t make me feel drowsy at all, which was a big issue with other allergy meds I’ve tried. I can stay focused at work without feeling foggy or out of it. Most importantly, it’s fast‑acting and provides non‑drowsy relief! If you're looking for something reliable that won’t mess with your energy levels, I’d definitely recommend giving Allegra 24‑Hour a shot.
