The military did a nice test of this. Most tablets maintain >90% potency even 10 years after expiration. Medications that are liquid or require refrigeration are the ones that don't last.
If you keep them dry, solid powdered drugs are probably fine decades after you buy them.
How i deal with the expiration date is to ignore it and take the meds anyway

Quote from PocketsThick :
I have yet to take this generic Claritin (allerclear), I have it but haven't opened it. I instead tried the more expensive aller-fex from Costco (generic Allegra) and I don't get any drowsy symptoms. I stopped taking generic Zyrtec and it's close cousin Xyzal because I get so drowsy taking it. Like once I go to sleep it's a struggle wanting to leave the bed.

People taking allergy meds probably want to try sampling several varieties to see what works best. The downside to Allegra is the price and the size of the pills. If you don't need 24 hours of relief you can split the pills in half to get about 12 hours of allergy relief.

You are correct. My (seasonal) allergies began out of the blue about 15 years ago and it took 2-3 years to get into a rhythm with the correct meds. Then it seems every handful of years, I'll get side effects I never had previously. for example I had been taking Zyrtec (or generic equiv) for 4-5 years then one year all of a sudden it would make me really drowsy. I started with Claritin, then to Zyrtec and now on Allegra (in addition to flonase and pataday). Good thing these are all now OTC and generics are available - pataday used to be $150/mo Rx and now you can get 3 bottles for $20 laugh out loud

Not so fast there…I took some Theraflu a year past its expiration date, unknowingly at the time, and I had the worst diarrhea ever. A good 27 times in a 10 hr period. You've been warned.
Theraflu comes in pill form?

Last time I ordered these, the expiration date was less than a year. These are daily, 365 in the container. They should at least be good a year. Buying 5 I guess is fine if you are giving the other 4 to someone else.

Not to my knowledge, I was commenting on the powdered drugs reference. I did not take solid powdered drugs to be pills, though I concede the point.

In Europe it does. It has both powder and a pill form.

Claritin should not be taken for more then a month at a time , Allegra can be and is also non drowsy
Curious, why can't you take claritin more than a month at a time? Any evidence to support this or is it just anecdotal?

So, you had the flu, and you got diarrhea.

And you're blaming something else, and not...you know...the flu?

Works for Kirkland Signature Acid Controller (Pepcid) as well! Definitely one of the better Costco deals as of late.
This one? https://www.costco.com/kirkland-s...22594.html

Because it appears to be out of stock.

Pharmacist here. Space this apart from other meds where you can. It interacts with quite a few because it occupied multiple commonly used enzymatic pathways in the body (2D6 and 3A4). 2-4 hour gap should be enough. If you don't want to deal with timing adjustments, desloratadine is better

Not that you were asking me, but I've been taking Claritin for years (4-5 years at least?) and I found it wasn't working anymore. Assuming I gained some kind of tolerance for it? Changed to Zyrtec and its like a new me. Just ordered some of the kirkland allegra based on user comments here (used to take allegra when it was prescription only, then when it became OTC it got expensive to take).

This deal on top of using HSA account is a winner for sure!

That's the one that was in stock when this was first posted. If you want something stronger, you can get Omeprazole instead. It works better, than Pepcid but for me, I prefer Famotidine since it isn't as powerful.

30 years ago I think I was paying $50 for a small number of allegra, and it was so worth it to finally have some relief! Now I keep the aller-clear and aller-tec both on hand, and I only need 2-3 per week during the spring and fall. I switch back and forth with what I take, and my pollen allergies are not bad at all.

Gonna pass on this deal because what I have now will last several years, but it's well worth the price if you need them.

I was waiting for that one. It's for cold And flu.

Thanks for sharing this advice!

A separate question: Do you have feedback on whether it's important to periodically switch up the antihistamine we take, so that it doesn't become less effective as our body adapts to it over time?
