Typical retail ranges, not quotes. What you are charged depends on the pharmacy and on how the claim is processed — which is exactly why it is worth asking.

Where the money goes

Brand Synthroid is many times the price of generic levothyroxine for most people.
If you switch, ask the pharmacy to keep you on one manufacturer consistently.

What else there is

Not recommendations. The tradeoff matters more than the name, and it is the part a prescriber will want to talk about.

Generic levothyroxineDifferent class

Much cheaper than Synthroid. The one real caveat on this page: small differences between manufacturers can matter for thyroid dosing, so if you switch, stay on the same manufacturer and have your levels rechecked.

Worth asking

Is generic levothyroxine reasonable for me?
If I switch, when should my levels be rechecked?

Before you change anything.
