High value of T4 and T3

[daphny]

My TSH value is <0.03 mIU/L
Ferritin is 10 ug/L
Free T4 is 55.84 pmol/L
Free T3 is 25.30 pmol/L

I have been given NEOMERCAZOLE 10mg 1-1-1 for a month.  
What precautions we need to take? How soon can this be cured?  Is this a Chronic condition?

Your ferritin is low, how is your hemoglobin?, RBC count? hematocrit?, tranferrin? vit B12 and folic acid? you probably have anaemia, you should take oral iron.

The hyperthyroidism can be sign of Grave's disease [chronic autoimmine condition or beginning phase of thyroid inflammation [thyroiditis]
