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-00000073-QINU`"' The long half-life gives smooth, once-daily BP control with low rebound. CYP3A4 substrate; pedal edema is the characteristic, dose-related, non-fluid-overload side effect'"`UNIQ--ref-00000074-QINU`"'. (1)
