Best Allergy Medicine of 2025

"I've repurchased this because it works so well and is much more affordable than the name brand. Buying in bulk is great since I take it every day. I save smaller bottles to transfer from the bigger one, which is really a time and space saver. This bottle is simple, and I get a year's worth of my allergy meds for much less money. I highly recommend it!"

"I just started using these and they are working really well. The savings are a big plus too!"

"This is a great generic alternative to Zyrtec and the price is fantastic. I would definitely buy it again!"

“This is just like the Benadryl you get from the store, but at a fraction of the price. I’ve tried both the name brand and the generic, and honestly, there’s no difference in effectiveness. I’ll definitely be sticking with this option in the future.”

“I really like this product because it is comparable to Benadryl allergy tablets and works well.”

“This works just as well as Claritin and is a fraction of the price for way more tablets. It cleared up my stuffy nose within 30-ish minutes with no other issues.”

"I have seasonal hay fever and found this A2Z brand on Amazon. BINGO! A small pill at a much better price. I can't believe I got nearly a FULL YEAR'S WORTH of 24-hour pills for less than $12! They work as well as the costly brand-name pills!"

"We've reordered this product multiple times. It works for us! Living in a multi-pet household, we need effective allergy meds, and this one does the job. Economical and convenient—definitely a yes from me!"

"This product is performing just as well as other generic brands I've tried, but the price is significantly better. I'm satisfied with my choice!"

"My doctor recommended purchasing Zyrtec and Cetirizine together. The price difference is astounding—12 pills of Zyrtec cost twice as much as 300 pills of Cetirizine. It's essentially the same product, and I take it daily."

"I've found this product to be an excellent value compared to the name brand. It performs just as well, and I tell everyone about the significant savings they can enjoy by choosing this brand!"

"These pills seem to work just as effectively as any other cetirizine or Zyrtec I've tried. The price is fantastic, but I did take off a star because the pills are rectangular. It's a bit unusual, but it hasn't caused any issues for me so far."

"I've struggled with itchy hands for over 40 years. This antihistamine works just as well as Zyrtec to keep me itch-free. I'm happy with the price point."

"These allergy pills are fantastic! I only need to take one every 24 hours. With 365 pills, it's a year's supply and cheaper than Walmart. My doctor even suggested I order from Amazon for better prices. Shopping around really helps, especially on a limited income."

"I've been using this medication for years and had it on subscribe and save, but last month the price jumped from $12 to over $50. I was shocked to see the price go from $12 to $52 overnight. I had to cancel my order. The product itself deserves 5 stars, but the pricing issue is disappointing."

"This allergy med works just like Claritin, but it's much more affordable. I would definitely recommend it."

"I find this allergy medicine to be great. There is no difference between this and the name brand, plus it's more affordable and still HSA/FSA eligible, which is fantastic."

"I've been using this alongside Zyrtec. While it's not as effective as Zyrtec, it does just fine and has no side effects."

"I used to rely on Zyrtec, but it stopped working for me. I’m so glad I gave this a try; now I have zero allergy symptoms and it’s incredibly affordable!"

"The quality of these pills is always great. I can easily order when my supply is running low and I don’t have to worry about forgetting them during grocery shopping."

"I take a lot of pills, so I appreciate getting lots of them for a low price. I trust that they are doing their job."

“I needed something for an incredible rash itching. Benadryl didn’t work, but this did the trick—no more itching. Great price too.”

“This works best for me, but my doctor says I should cycle through it for only 6 months to maintain potency.”

“I have used this product for years. It works perfectly for what I need.”

"I've been using Allegra for a while now, and I find that the price for quantity is much better than Walmart. It consistently helps me manage my allergies."

"Allegra is my go-to when it comes to allergies. I usually take it a few hours before traveling to avoid allergy issues, and I've found that taking it at night works best for me. I experience little to no allergic reactions during the day. Although it's on the pricier side, it definitely does the job."

"These are prescribed by my doctor, and I take them daily alongside my other allergy medications. I love the convenience and lower price from Amazon; they arrive quickly, ensuring I never miss a dose."

"I’ve been using Zyrtec for over 10 years. The recent generic options don’t work for me at all. If you suffer from severe allergies like I do, this is the medicine you need. I prefer the gel caps as they are easier to swallow, especially with age."

"This product is a very effective antihistamine that definitely gets the job done at a reasonable price."

"I really prefer the liquid form of Zyrtec. It seems to act faster and provides longer-lasting relief."
