Synthetic T4 (thyroxine); peripherally deiodinated to T3 (triiodothyronine), the active hormone. '"`UNIQ--vote-00000031-QINU`"' Narrow therapeutic index; brand-to-generic switches can shift TSH and require re-titration'"`UNIQ--ref-00000032-QINU`"'. (1) ·
'"`UNIQ--vote-00000032-QINU`"' Brand-to-brand and lot-to-lot variability in T3:T4 ratio is greater than with synthetic levothyroxine, which is why endocrine guidelines prefer the synthetic'"`UNIQ--ref-00000033-QINU`"'. (1) ·
'"`UNIQ--vote-00001302-QINU`"' Renally cleared; accumulation in advanced CKD can produce neuromuscular and cardiac depression. Hypomagnesemia frequently co-exists with hypokalemia and is often the reason refractory potassium loss does not correct until magnesium is repleted. (1)
