Question: Hi

Last Friday I received some blood results which showed I had a severely underactive thyroid. I have attached the report, please check these for reference.

I had slight dizziness and lethargy over the last few weeks but my symptoms gone downhill massively by Monday. Lots of dizziness, vertigo ect set on by Tuesday and I felt like I was practically drunk walking around.

On Tuesday evening I started my first dosage of Levothyroxine 50mcg. Around 1 hour later I noticed some shortness of breathe and tightness in my chest.

Its now Thursday and I have taken my third 50mcg tablet of Thyroxine today. And again I noticed the same shortness of breathe and tightness in my lungs. The feeling tends to last for about 12 hours after taking them sometimes more.

I am asthmatic and I take Fostair 200/6 4 times daily.

So shortness of breath and tightness in lungs after Levothyroxine?

Since starting the Levo I have felt more energy ect, but its just the shortness of breathe that concerns me a little.

Brief Answer:
May be due to levothyroxine...

Detailed Answer:
Hi,

Levothyroxine generally is a well tolerated drug among masses. But few people have reported shortness of breath, tightness and other side effects after levothyroxine. It should get better in a few days. So do not be worried.

Hope this helps. Let me know if you need clarifications.

Regards
