I take hyrdocodone periodically because of the bad headaches I get. I have had periods where I take it everyday for a week. It has never had any reaction to my thyroid meds I take armour. But I would take them 2-4 hrs apart like laura said in her post to be safe.
Make sure you take them at least 2-4 hrs apart. I just had surgery and took hydrocodone. I am on synthroid and cytomel for my thyroid. No problems noted.
Hydrocodone on the other hand is a whole new set of problems if you start taking those every day. No thanks.....I would look at a different avenue. The narcotic pain meds are too addictive physically and psychologically.
