Hi all, new to this forum so firstly hello! I've been prescribed Eltroxin after a rollercoaster ride which has encompassed a Cushings diagnosis(now Dr says that was a mistake - I just have v high cortisol that won't supress), b12 and vitamin d deficiency diagnosis (currently on supplements), panic disporder (diazepam, antidepressants and psychiatric consultation). Finally I'm here with a hypothyroid diagnosis. TSH 8.9, T4 19, T3 5.6. dHEA 1.8. Having done a bit of research I asked my consultant about natural thyroid or T3 and he said he would not prescribe under any circumstances. So I now have a box of eltroxin and I feel terrible. I've been taking it for 3 weeks at 50 mcg with instructions to move up skiely until i was on 100. After a week I started to have palpitations, insomnia, feeling on edge and ready to snap and totally lost my appetite but also absolutely no energy to get out of bed. I've dropped down to 25 mcg after reading that some people need to titrate up and still I feel terrible. Exhausted and horrid. Am I allergic to Eltroxin? Do I just need to give it more time? Should I start taking more? Or stop it completely? My GP says he doesn't know and that I need to wait for my consultant app in 4 months! Please help - I feel awful!
