Do you take a brand name replacement such as Synthroid or Levothroid? If you take a generic, your pharmacy can switch generic brands and all generics aren't alike. If you do take a generic, you may want to get your doctor to prescribe a brand name so your dose will remain consistent.
If you do take a brand name, another possibility for requiring a dose change is recent weight gain or loss.
Good luck to you!

Get your thyroglobulin (Tg) checked asap. Sudden increase in TSH while being on stable meds, combined with an increase in Tg could indicate a recurrence.
Before messing with the meds, get your levels checked and *insist* on Tg.
