    One quick note: the American Thyroid Association recommends followup testing if you switch products in order to confirm that the dose of the new med is correct. After that, as Liz1967 noted, it’s best to stay with a consistent manufacturer. (You should be able to keep tabs on the manufacturer via a 3-letter code on the label. Your pharmacist *should* inform you of any changes, but this doesn’t always happen!)
