This pill is about 1 across with A-24 imprinted on the top ## I am looking for the same thing. I was told it was tylonel and just wanted to make sure. So if anyone knows that would be great. ## Comes from CVS it is for allergies. :) ## This is a 10mg Alavert (Loratadine) tablet that is used to treat allergies, as Jessica stated. (For details here is the NDC 00573-2620.) The FDA lists its typical side effects as possibly including nausea, dizziness, headache, and dry mouth. Are there any questions?
