Hello,
Levothyroxine is a medicine used for the treatment of
Hypothyroidism. There are different brands of levothyroxine available. (like
Euthyrox or
Synthroid for e.g).
It is true that different brands of this medicine have a different influence on your body and it is possible that you may need different dosis to have normal
TSH result with different brands.
As you mention, your maintenance dosis is 37,5 mcg Euthyrox. I want to underline that you should not stop taking thyroid medicine, it is vital for your body.
At the other side, it is very important to not change the dosis without talking with your treating doctor.
If you cannot find Euthyrox in your country and you do not prefer Levothyroxine, my advice is to ask the pharmacist for other brands of Levothyroxine.(Synthroid can be a possible solution).
I suggest repeating the TSH test 6 weeks after changing the brand of your thyroid medication because it can be necessary to adjust the dosis.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Elona Xhardo, Endocrinologist
