Westhroid vs Naturethroid

[Doodeet]

Will I be able to tell a difference when switching from Westhroid to Naturethroid next week?

Looks like same active ingredients, but different "inactive" fillers, see main thyroidUK site

thyroiduk.org.uk/tuk/treatm...

and click on purple bar labelled 'Non-UK Dessicated Thyroid (aka NDT)

May depend on whether you react to any of the fillers. Let us know if you find a difference.

Are you meaning the "old" Westhroid product?

Or the more recent "Westhroid P" - now re-named WP Thyroid?

The "old" product was exactly the same as Nature-Throid - untold many years ago they were slightly different but they were identical for quite a number of years. (It was said they retained the name to avoid confusion.)

WP Thyroid is a different formulation which has only two other ingredients.

You might notice a slight difference - but they are intended to be the same potency.

The Westhroid I'm taking doesn't have a P. My new Doctor prescribed Naturethroid. Just worried it will affect me differently.
