I have just got around to joining this online community, so greetings to everyone
I was diagnosed hypothyroid 20 years ago, and have never been well since, on treatment. I am on liquid thyroxine after some problems with tablet quality a year or two ago. My blood results became stable on the liquid. In February, I began splitting the dose into morning and evening, and it immediately felt more natural; I no longer had hyper symptoms along with the hypo ones. I am still in a phase of reaching for good health, and getting the dose to the most advantageous.
BUT, since the hot weather in summer, I have twice strongly suspected that my liquid has been under potent, degraded by the heat. I think it is happening again now with the bottle I am on. I know from official documents (at MHRA mhra.gov.uk/home/groups/pl-... and, I think the American equivalent?) that levothyroxine sodium is heat sensitive and unstable. TEVA (the label on one of the bottles in question -- not the manufacturer) are analysing a sample, and I am waiting -- and waiting .. for the result of that lab test, so I can know for sure whether or not the medicine is the cause of that health dip. The pharmacy, their wholesaler and TEVA have all been exceptionally kind and helpful.
I have been more unwell than usual most autumns that I have been on thyroxine, and wonder whether there could be a general problem with medication which has been in the supply chain through a heatwave.
What I'd like to ask on this forum is: has anyone else noticed health dips in autumn? And, has anyone been aware of a drop in thyroxine quality following heatwaves?
And I'd just like to say that autumn used to be my favourite season!
