I take Singulair every day, & I just rotate through the OTC allergy meds when I feel they stop working or aren't cutting it. Right now I'm not really taking anything OTC daily, but when I do take something, it's the Mucinex Allergy med (which is really just Allegra, if you ask me). Usually I take loratadine. A long time ago Alavert used to be a godsend for me, but at that time, I couldn't afford it anymore, so I switched to generic Benadryl, which is usually super cheap.
