My father started taking thyroxine 25mcg (1-0-0) when his TSH detected around 14 six months ago and continued same dosage and around 3 months ago, his TSH came down to 5.83 and continued taking the same medicine in same dosage and now his TSH is slightly increased to 6.8, so any change in dosage or what??? I want his TSH to reduce to around 2. So kindly suggest thyroxine dosage. Apart from thyroxine, any other options to reduce and manage the same??? Your genuine responses will highly be appreciated. Thanks in advance
