I have Hashimoto's and I am taking Synthroid, I went to another MD for an infection and informed him of all the medications I have been taking and that I had Hashimoto's, He put me on Ciprofloxacin (1 500mg Twice a day) for 10 days, He nor the Parmacy informed me that an interaction would be caused with my Thyroid medication, I found this out after the fact, I have pasted a link to the article here:

I thought doctors would keep up on these drugs, I guess not!
Please read, I would also look up the side affects of this antibiotic (Group) prior to taking it, even without a thyroid condition, it has some really nasty side affects. Thank You
