Tasigna and thyroid problems

Hello to all 

I have been taking Tasigna over the last year and most of the side effects are tolerable in my current situation.  I have noticed over the last few months my exercise capacity has gradually been dropping. Over the last few weeks though it’s now become a real struggle due to excessive fatigue and no energy.  Blood tests are all normal so I’m now wondering if this could be linked to a thyroid problem having read that Tasigna can sometimes cause delayed problems with the thyroid.  Have any of you had any similar problems?

 

 

I was slightly low thyroid, and became more so on both Tasigna and Sprycel.  They can interfere with the thyroid med, now right on the list of interactions.  It is an easy blood test to find out.  I recall there was some question if there were some cases where the TKI directly interfered with the thyroid?  I'm reaching back in memory for this as I'd done some looking when I was having troubles stabilizing on the TKI.  A higher dose of the thyroid med brought my numbers back to normal.

Thanks for the reply 😊

How did you feel when your thyroid was causing you problems?

 

Low energy.  My neck gets very stiff and sore.  And my eyes get dry.  It is an easy blood test to find out.  Good luck.
