davecom Posted April 4, 2013 Report Share Posted April 4, 2013 Is it safe to take an antihistamine during this test or will it affect results? I can't find any info online. Can anyone point me to a resource online that states one way or the other? Quote Link to comment Share on other sites More sharing options...
Katybug Posted April 5, 2013 Report Share Posted April 5, 2013 If you take an antihistamine it will suppress histamine release and therefore invalidate the test results. I don't have a reference for you but that is my understanding of how that drug class works. Quote Link to comment Share on other sites More sharing options...

corina Posted April 5, 2013 Report Share Posted April 5, 2013 I agree with what is written above. In your personal situation however there may be reasons why you shouldn't stop the zantac, so I'd advice you to talk this over with your doctors to decide together what will be best for you. Good luck! Quote Link to comment Share on other sites More sharing options...
davecom Posted April 5, 2013 Author Report Share Posted April 5, 2013 Thanks for the replies everyone. It was very very helpful. I am avoiding Zantac last night and today. It is a challenge but hopefully these tests will be worth it. Quote Link to comment Share on other sites More sharing options...
