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.

My thyroid meds make me feel sick also, I take 50 mgn daily for the past twelvee years,don,t stp taking the med,talk to your endocrinologist and get your blood checked each month for your tsh levels, u can take multivitamins and vit D FOUR hours after your meds,get your iron level checked also.f it was me, I'd stop taking it to see if I felt better, but this med should take several weeks to 6 weeks to get into your system and may take days to get out. I'm just surprised it worked that fast. Some of your symptoms aren't that of taking too much thyroid hormones, though.
