hypothyroidism, after thyroid removal
"Had my thyroid removed at age 9 (cancer) 38 yrs ago. Been on Synthroid ever since then. My dosage has changed over the years. I am now on 150 mg (blue tablets) I have been getting a all over skin rash and itching for the last 4 months.  After numerous tests my doctor told me it may be the dye in the blue 150 mg tablets.  Has anyone else experienced this problem?  I just switched today to take the 50 mg (white tablets with no dye) three times a day. I am hoping this was the problem."
