What Should I Do If I Miss a Dose?

If you do not take your liothyronine as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose. Each time you get your blood tests to monitor your thyroid function, be sure to tell your healthcare provider if you have missed any doses, as this may affect any dosage adjustments.
