Frequently Asked Questions
Is generic levothyroxine the same as Synthroid?
Generic levothyroxine contains the same active hormone. The FDA requires bioequivalence. However, inactive ingredients differ across brands and generics, so switching formulations warrants a TSH recheck in 6–8 weeks.
Why do some doctors prefer brand Synthroid over generic levothyroxine?
Some endocrinologists prefer consistent brand therapy because small bioavailability differences between manufacturers can shift TSH in sensitive patients. The American Thyroid Association recommends sticking with one consistent formulation.
Should I take levothyroxine on an empty stomach?
Yes — levothyroxine should be taken 30–60 minutes before food, coffee, or other medications. Calcium, iron, and certain medications interfere with absorption.
What does generic levothyroxine cost through Script Unlock?
Generic levothyroxine is among the cheapest medications available — $7–$13/month. Script Unlock pharmacies can offer competitive cash prices even at this baseline.
Does levothyroxine dose need adjustment over time?
Yes — TSH should be rechecked 6–8 weeks after any dose or brand change, and annually once stable. Weight changes, pregnancy, and aging all affect dosing requirements.
