thyroxine dosage

Can anyone tell me if 12 and a half of levo could be enough. If I try to go higher I seem to be worse. Have struggles for many years trying to increase dose. Am no better on NDT or T3 only.

I can see this is your first post, although understand you’ve been a member for several years; welcome! We are a friendly and supportive group and are here to help.

Please can you share your most recent thyroid blood test results with us, so we can offer better advice.

What is your current medication/ dosage? When did you last adjust this?

Have you tested key thyroid vitamins (folate. Ferritin, B12 and Vit D) as having these optimal supports thyroid health?

Can you add ranges in brackets to above results, as these can vary between laboratories.

What is your current dose of Levo and how long have you been consistently on this dose?

I would 100% get FT3 and FT4 checked before considering medication again. Your FT3 and FT4 in January are too old to advise on.
