My mother is a hypothyroid patient from last 8 years. She is having her regular medicine of 75mg. She recently has gone through thyroid profile. Her results are as below FT4 - 1.63 (normal range 0.89-1.76) FT3 - 2.89 (normal range 2.30-4.20) TSH - 2.4 (normal range 0.5-4.7) Just want to have this opinion that should she continue 75mg Or should reduce the dosage to 50mg Or 25 mg regular dosage. Please suggest
