Thyroid Med side effects

[lazybeagle]

"I recently took a thyroid medicine (t4), Levoxyl, for 2 days.  I have been having heat intolerance, muscle cramps, irritability which I see they list as possible side effects.  How long does this medication stay in the body and how long might I expect to have these problems?

If you look closely, you will see that every symptom of hypothyroidism, and half the symptoms of hyperthyroidism are listed as possible side effects of taking Levoxyl.

It is possible you might have side effects from taking the drug, but two days seems like a short time to develop side effects other than a rash. It takes six weeks to come up to full strength in your body, and a week to notice any changes to speak of.

Is it possible that you are experiencing symptoms of being hypo, which is why you were put on the drug?

Thanks for your answer.  Recently diagnosed with a low t4.  Took it 2 days ago.  for 4 days Ive been feeling nearly faint in even 75 degrees, and legs are cramping and muscles twitching.  

Do others have severe side effects that later go away?

Did you stop taking the medicine? Why did you take it in the first place?

They are side effects that can eventually go away. It takes time though. 2 days is not enough time to let the Levoxyl do it's job.

I am no expert...I'm sure a few others will chime in with better advice.

Good luck.
