What effect does birth control pills have on your Thyroid Meds?

[Guest guest]

Hello - I know this has been discussed but I've never paid much attention to it as my husband had a vasectomy 16 years ago. Over the last 3 months, I've had non-stop cycling and so the doctor has prescribed a very low dose bc pill to stop the bleeding until we can get me in for a biopsy(in the office biopsy was attempted yesterday but not successful, so now I will have to have a surgical biopsy). Also, she knows I have a vacation coming up in October. We may be looking at a hysterectomy. Anyway, I am on Armour and wonder what effects the bc pill will have on my thyroid meds, if any.

Thank you,

Marie
