is secondary to amiodarone
intake. You have to take lethyroxine lifelong. Best tome to take it is early morning n empty stomach and not to take anything during nexr 1 hour. Second option is to take it late night before going to bed. Your dosage will have to be totrated to maintain TSH
in normal range. Your throat symptoms have nothing to do with hypothyroidism even though they manifested around the same time. I suggest you consult an ENT specialist
to see if everything is ok in your throat. Hypothyroidism is a pretty straight forward problem &when treatment is taken properly wouldnt lead to any other new issues. So in my view you continue 87.5 mcg &repeat TSH after 4 - 6 weeks to see if it is in normal range &consult an ENT specialist for your throat problem.
Hope this helps.
