Pharmacy switched my levo without telling me

been stable on generic levo for three months. picked up my refill last week and didn’t realize they’d switched manufacturers - pharmacist didn’t say anything. hands went ice cold yesterday, which is my 48-hour warning, so now i’m worried this brand swap already hit me.

labs were solid last month but different fillers change absorption and i can feel it. free T3 is what actually matters to me, not TSH - i track it obsessively because numbers can look fine while i’m crashing. if this switch tanked my T3, i’m back to figuring out what works.

probably paranoid to stress about a generic swap, but it genuinely does matter. anyone else had a pharmacy switch your brand without notice? did it change anything for you?
