Hey everyone, are any of you on synthroid and on Tricor? If you have been reading my posts you will have seen that I have been having problems with shortness of breath and palputations, Thinking it was my synthroid I started adjusting my dose. Then I did have a slight problem with peanut allergies. After not eating peanuts, the breathing problems and palputations continued. Last night I looked up the side effects of tricor ( I started them mid December) by Christmas the problems started. Seems like the most common side effects are diffuculty breathing , shortness of breath and palputations. Most Hashimoto patients have high cholsetrol, due to the disease, not by what your eating. and I hope this post helps anyone that happens to be taking both. Me myself, I am stopping the Tricor today.
