Headaches on Synthroid

Posted , 4 users are following.

Hi everyone!

I started Synthroid over a month ago and about two to three weeks ago I started to get mild tension headaches. I had heard that thyroid medication can cause headaches so I just presumed its that. And the headaches started when I was told that that medication would start to full kick in. I mentioned it to my doctor and he said that you usually don't get headaches from it but then when on to say but if you continue to get them to come it and we'd change the medication. So I'm kinda confused on what I should do. I wanted to get your opinion and ask if you guys have gotten headaches from Synthroid? How long did they last? should i change my medication or just wait it out and see if they go away? The headaches aren't bad I just get more worried more than anything. And sometimes spiral and think its the worst of the worst when it's most likely something minor. Oh and i guess i should mention that I was diagnosed with Hashimoto's and have the autoimmune version of hypothyroidism. Any other advice or opinions would be great too. I'm newly diagnosed with hypothyroidism/ Hashimoto's.

    Hi Emily. I've been on thyroid meds for several years. Shortly before i switched from levothyroxin to Synthroid, my only problem was extreme fatigue. I also have antibodies attacking my thyroid and see the endo every 6 months to check the parathyroid situation. hope you get some relief.

      I started seeing the Endo because of a possible parathyroid problem. My primary Dr still oversees my diabetes care and the thyroid issue. On one of my visits with the endo, I mentioned how very tired I'd been lately and he said that sometimes people like me did better on Synthroid than levo. He gave me some samples to try and within 3 days I felt so much better that I called my PCP and asked her to change my prescription. I did not have headaches though. If you are happy with whoever is treating you now, there's no need to change. An Endo has just specialized in hormonal stuff.
