I still feel I have developed allergy to my Thyroxine medication.Feel a slight swelling on my top lip, especially when I take 75 mcg Went to Doc and he changed it to Oroxine,as the chemist said,it is still the same. Same machine,same ingredients . Can I take antihistamine all the time with my Oroxine.Am going to specialst on 5th.Was supposed to go today but he had a bereavement in the family.Why would this start after all these years,have been on thyroxine 30 years.Anyone know the solution to my problem.? I am a bit anaemic,taking spatone every day to correct it, also Vit d tablets,fish oil and magnesium asparte. Still taking Atenonlol,did cut down but BP went sky high,so will still take it for the time being.
