I always have my thyroid, cholesterol, blood sugar etc checked whenever I start a new med. Like, I'll get my blood tested before I start the med, then get it tested again 2 weeks after the med had been in my system.

My thyroid was fine at the time I was Dx'ed with BP. Now my results indicate probable hyperthyroidism, but I have a strong family history of hyperthyroidism, so I don't think any meds caused it. It sucks A LOT!
