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.

People who are taking thyroid medications should avoid foods made of soy because soy can interfere with the proper absorption of the medicine. While soy does not have to be avoided completely, patients taking thyroid medicines should wait at least four hours after taking the medicine to eat any soy products.
