Hey, so I've got hypothyroidism and I'm on levothyroxine, taking 100mcg a day. I've been wondering about what might happen if I accidentally took 2 or 3 pills one day. Is there a risk of something really serious happening, like dying from taking too much? I get a bit anxious because sometimes I forget if I've already taken my dose for the day, and I've always been curious about just how dangerous it is like, how much would it take for it to be really harmful?

Taking more than the prescribed dose of levothyroxine can lead to symptoms of hyperthyroidism, such as palpitations, weight loss, and irritability. In severe cases, it can lead to complications like cardiac arrhythmias or osteoporosis. However, it is unlikely to be fatal unless extremely high doses are ingested. It is important to take your medication as prescribed and if you are unsure whether you have taken your dose for the day, it is best to skip it rather than double or triple the dose. If you are frequently forgetting whether you have taken your medication, you may want to consider using a pill organizer to help keep track.
