I have been considering going back on either Erfa or Armour which I have a prescription for. The reason is that I feel that Thyroid-S has been weaker and more inconsistent lately, but that could be due to other things such as cortisol deficiency.
Also, more generally, I'm worried about what's happening to Thai NDT - one brand has already been discontinued, Thiroyd seems unavailable ATM as well, and I don't like relying on one single brand that may or may not continue to be available.
I have not been on prescription NDT since 2014. I took Armour from 2011-13, then it became unavailable and I switched to Erfa which I never found great. That was right after the STTM reported problems with it.
As far as I recall, I did OK on Armour, but probably never worked myself up to the dose I need for complete symptom-relief. I remember chewing the pills up to break down the cellulose (as recommended by STTM) and that may have helped as well. Anyway, I don't remember it being so disastrous as reported by STTM...to me, Erfa was worse. But that could be due to the fact that switching brands can mess you up, so not entirely sure that was all Erfa's fault...
I have been in touch with two Belgian pharmacies and they carry both brands.
My doctor claimed that Erfa has been reformulated to have lactose removed, and that's the reason the pills now look different. There are photos on the STTM showing two different pills, one (the "reformulated" one) looking more blotchy than the other ("old" Erfa), but removing lactose would make it work better, rather than worse...so not sure my doctor is right about that. She claimed the lactose is what made "old" Erfa white, and removing it made the pills more grayish.
Anyway, I'd be interested in input from those of you on either or Armour or Erfa (no other brand of NDT is available in Belgium). Is Armour working better now than right after the unappreciated 2009 reformulation (there is some anecdotal evidence it is although I don't understand why)? Is Erfa still problematic? I don't trust everything the STTM says (according to them, there seems to be a global conspiracy against NDT going on) but, given the price of prescription NDT, I'd like to hear about other patients' more recent experiences before I decide to try it again.
