    Question warfarin and antihistamines

    Allergy season has arrived and I'm wondering anyone knows of an antihistamine that does not affect INR levels unduly?

    Thumbs up

    I take Benedryl and, if thing get really bad, Claritin. No problems with either one.

    A doctor told me Claritin D will have no effect on my INR.
    Havn't tried it yet so I can't be sure.

    The antihistamines are all pretty safe with warfarin.

    Hi Ross,

    The one I was thinking of is Aerius. However there are a lot of good suggestions here so most of them will probably be all right.

    Thanks

    I've taken Allegra 180, Claritin, Zyrtec and Benedryl with nothing to report as of yet. Aerius is the same as our Clarinex, so you should be fine.
