I have received my 2 weeks supply of erfa ( my last prescription from dr Skinner) . I used different pharmacy this time as old one had some delays. Anyway this new tablets do not have this distinctive smell and taste as it used to be the case with my previous supplies. I tried them and they don't give me this slight ' kick 'as usual , my temperature doesn't raise as it used to after taking the old tablets. Tablets are well in date but I am really worried that they Lost their potency, maybe the pharmacy exposed them to air or stored in a wrong temperature. I will call them on Monday but if that's the case I will have another setback. And then chasing for another prescription and looking for doctor who would prescribe. I am so tired of this hypothyroidism , sick of chasing ndt, I dont like getting them via post. I wish I could take levothyroxine and be done with it.
