Many of the signs of hyperthyroidism caused by taking too much levothyroxine can be found in the skin. Too much levothyroxine can make the skin unusually warm, due to increased blood flow. Levothyroxine also increases metabolism, causing your body to generate more heat.
Re: how long does it take for levothyroxine to start working after taking it. I started on 25 mg of synthroid about 1 year ago (TSH level was about 9) and definitely felt positive effects, like more focused and energized, after about 3-4 months i was put on 50mg and still felt ok.
