    Your personal physician is the best source on this issue, but I don’t believe antihistamines are a problem, even for those of us who still have our thyroids. Cold medicines — which typically contain chemical “uppers” are what we are warned about while hyperthyroid. But the best thing to do is check with your doctor. Failing that, a pharmacist might be able to provide the necessary information for you.
