I read an article that said SOME allergy drops do. I'm on Pataday and I know I do NOT want a vasoconstrictor in it. I looked it up on google but couldn't find anything.
I don't think it does, the only ingredients in it were a mast cell stabilizer and an antihistimine. It definitely doesn't seem to shrink my blood vessels like vasoconstrictors do, either, but I thought I would see if anybody knows for sure. I don't want to be on something like that for long.
