Earlier in April .she was diagnosed with thyroid ...then tsh was >100 ...and she gained 4  kg weight ...thought normal weight gain.but she had facial swell and fingers swollen...then immediately met doctor .and found hypothyroidism...after 6 weeks of medication tsh is 10.85 ..t3t4normal. Now the doubt is to continue 75 mcg thyroxine or increase the dose to 100 mcg ?...how long it takes to come to normal tsh level? Even after coming to normal sholud medicine be continued?
