5 years ago. It is different for everyone how long the meds take to work. You should be scheduled for a blood test at about 6 - 8 weeks after starting levothyroxine. At that point your dosage may be adjusted, and then another blood test at 6 - 8 weeks.I have realized that being hypothyroid is a test of your patience, it all takes time. My levels stabilized about 9 months after starting medication.Some people take longer than that. But hopefully you will see some improvement within the next few weeks.t that point your dosage may be adjusted, and then another blood test at 6 - 8 weeks.

I was wondering how long it takes before the thyroid medicine starts working. I was diagnosed with Hashi's last week (TSH 65 - under 3 normal, FT4 and T3 under 1, Antibody 600 - normal under 40), and started taking 125 mcg of Synthroid Monday. I know 4 days is probably too early to start working, but I swear I feel worse. I can't sleep much, even though I'm extremely tired.
