I cant tell you what the shelf life is of synthetic thyroxin when not refridgerated.Maybe it just night be worth seeing if you need an increase?
i didnt think it would go badly that quickly either, but the nurse said it didnt seem like i was taking my meds at all...so i thought maybe my pills were bad In Australia, thyroxin is kept refridgerated and is discarded usually on the date of the box.But usually thyroid hormone (T4) expires after 12 months refridgerated.hi all, I've been slowly increasing my dose of levothyroxine for the last three months and every time I go back to get my TSH tested my numbers don't change much. i looked all over the bottle and there is nothing that says discard after or anything similar to that. I have tons of hypo symptoms like extreme fatigue, difficulty losing weight, cold all the time, daily headaches, mysteriously bruise easily and the bruises take forever to heal, etc.I was prescribed a 50mcg tablet back in November and had been cutting them in half and I had two 60 day supplies, so i am still using the same bottles. I don't think the levo will go bad that quickly; however, on the prescription label, there should be a "Discard After: Date"........
