Are the brand name "synthroid" &levothyroxine equally effective? m taking synthroid. can i switch 2 levothyroxine, looks like levothyroxine is cheaper

Yes, identical: Hi. Brand name Synthroid and generic levothyroxine are chemically identical hormones, l-thyroxine. The inert ingredients vary, but that's trivial. If you switch to generic at the same dose, you should check your TSH and free T4 in 2-3 months to make sure your replacement dose is still OK. Good luck!

Levothyroxine is: cheaper since it's a generic, but the blood levels with Synthroid (thyroxine) are more consistent and reliable. It is a product with a "narrow therapeutic window" where generics can vary from batch to batch, company to company and prescription to prescription -- while the brand name product does not. If you can afford it, take the brand name drug.
