well let me tell you i've done the same thing occasionally! sometimes it's hard to remember if we took the pill or not or else we inadvertently toss two tablets into our palm and they're down our throat before we know it. luckily doubling up on synthroid (levothyroxine) isn't going to have any long-term consequences for you. as you already know it may make you feel stimulated jittery or energetic for awhile. those feelings should pass by the end of the day. you can resume your regular dose tomorrow. meanwhile you'll just have to wait out the jittery-ness. and don't drink any coffee tea or anything that can make you even more jittery. stay well!
what to do for accidental double dose of synthroid. after taking a double dose of synthroid 75mcg each can i take anything to counter act the increased stimulated feeling or do i just wait it out?
