A member asked:

What happened to the allergy medicine 12 hour chlortrimeton, or any chlorpheniramine maleate 12 hour version? i'm asking in 2022?

It is a decades old popular antihistamine. I can find vendors for it on eBay and other online sources but some say it is out of stock due to high demand. Its use and value has been supplanted by other readily available antihistamines with fewer side effects.
