I've been taking Euthyrox 0.175mg (175mcg) Tabs for a while now to manage my hypothyroidism, and I've noticed some changes but I'm not sure which are side effects and which aren't. I want to know what side effects to watch out for and when to call the doctor. Has anyone else experienced side effects from this medication? What should I be on the lookout for? How do I know if what I'm feeling is serious or not?

Watch out for any signs of allergies. I had a friend who broke out in hives and had trouble breathing. She ended up in the ER, and they told her it was an allergic reaction to the medication. Scary stuff.

My kid started limping after we began the medication. We thought it was a side effect but actually it was growing pains. I was worried sick!

I started Euthyrox a few months back and I felt like I was on an emotional rollercoaster. Irritability, anxiety, and restlessness were my constant companions for the first two weeks. But my doctor said it was normal as my body adjusted. It is really important to take it as prescribed.

I am so over the stomach cramps and vomiting. It's been a week and I still have them. I thought the side effects were supposed to go away. Should I call the doctor?

I noticed sudden weight gain and swelling in my legs. It was really scary, but my doctor adjusted my dose and it went away. If you experience this, don't wait, talk to your healthcare provider immediately.

I had chest pain and shortness of breath. Called my doctor right away and they told me to go to the ER. Turns out it was a panic attack but still, better safe than sorry. No more Levothyroxine for me!
