Hives and synthroid, how long for synthroid to leave my system?

Thanks... what about the hives when taking synthroid?

Hey.. I started getting hives after they upped my dosage. I told my doctor he brought my doasge down. I've been on the low dose for almost 6 weeks.. and I'm still getting hives. Any luck on how they stopped?

I have been on levothroxine for 3 yrs 25mg, no problems. Dr just upped it to 50, and I have hives on scalp,back of ears, and even buttocks and top of legs. So itchy. What to do, feels like bug bites all over!

This happened to me when I switched to Synthyroid. My doctor would not change me so I went to a new endo. I switched to the cheap stuff and I am great. The hives went also every other miserable side effect anxious, shakes, palpitations and sweats.
Good luck

I have been trying levothroxine for Hashimoto's thyroiditis 3 times now and I develop severe hives rashes and itching everywhere very bad also palpitations and shaking dizziness I went off it completely for 6 weeks and after 2 weeks rash and itching away etc .I started again as I thought I needed it and now I am having horrendous skin eprasgphes itching hives dizziness and shaking I will stop again I think it may be an iodine or detoxing reaction iodine foods like milk nuts fish make the symtoms worse but I have to eat and these things are stable for a god diet .I am going to try and cure thyroid naturally with good diet and reduce tea consumption as very Hugh in fluoride also no fluoride toothpaste !
