Tablet Thyronorm comes in a number of strengths. If I remember correctly your T3, T4 were normal but your TSH was high. Such patients are considered as Subclinical hypothyroidism. In this none of the features of hypothyroid are there but by biochemistry assessment the thyroid is working at suboptimal level. There is no hard and fast rule about whether 25 or 50 mcg. None of these can cause hyperthyroidism. Once the TSH level comes down we may reduce the dose and may even stop Thyronorm.

Both aur se medicine with the different dosage If you don't have 25 micrograms now use half of 50 mcg

U can continue the same dose as per doctor

Consult

The difference is dose n strength Ideally if ur planning pregnancy tsh shud be maintained less than 2.5 If not then less than 5 The dose of tan 25 or 50  will be based on the value of tsh

Dosage is different If your thyroid level is in control in whatever dose u are taking,u need to continue the same dose to remain euthyroid

Hello , Difference btw thyronorm 50 mcg and 25 mcg is the strength of the tablet . 50 mcg has 50 microgram of the component levothyroxin and 25 mcg has 25 mcg of levothyroxin. If ur thyroid levels are normal on 50 mcg , ur doctor will step down the amount of medication given so as to find the lowest and most effective strength of medication required to maintain the same  normal levels.
