Thank you for the information.
I am sorry to hear about your symptoms.
Let me tell you that you are not experiencing any drug reaction by coming these two medication. There are minor issues by combining thee meds, but your doctor has taken care of that by adjusting your medication. Since you developed this loose stool after taking thyroid
meds, it is very likely that your problem is drug related. Diarrhea/loose stool has been reported by those who are taking thyroid meds, this is just as side effect. Once you achieve the right dose as per your need, many of these side effects subside gradually. Thus, in your case, the most likely cause is thyroid meds. However, there are many bacterial and viral
causes of loose stool. Thus, if you are experiencing loose stool for a while, then you can get blood and stool tests to rule out infection related cause. In the meantime, just continue with adequate water and maintain your hydration.
Please let me know if you have any other question for me.
