The dose of thyroxine is typically determined by the individual's body weight, with a standard guideline of 1.6 mcg per kg. Once you were initiated on a 75mcg dose, it's was important not to reduce it to 50mcg, even after achieving the target
TSH level. Consistency in dosage is key. Remember to take the tablet on an empty stomach with a minimum 30-minute gap before eating. For those planning pregnancy, aiming for a TSH below 2.5 is recommended. Therefore, continuing the 75 mcg dose is advisable for you . Follow-up testing of TSH, T4, and T3 levels should be conducted after six weeks.
