1. Dosage
The recommended dose is 500 μg once daily.
Take at the same time each day, with or without food.
Swallow the tablet whole; do not chew, split, or crush it.
2. Administration Time

II. Missed Dose Management and Dose Adjustment
1. Missed Dose Management
If remembered and there is still a long time until the next dose, take it as soon as possible.
If the next dose is approaching, skip the missed dose.
Do not take a double dose at one time.
After taking the missed dose, continue once daily according to the original schedule.
2. Principles of Dose Adjustment
Generally, no routine dose adjustment is needed.
If intolerance occurs, the doctor may recommend temporarily reducing to 250 μg once daily.
If tolerance improves after reduction, resuming 500 μg may be considered.
Dose adjustment must be performed under medical guidance.

Not recommended for patients with moderate or severe hepatic impairment.
Older adults usually do not require dose adjustment.
Low-body-weight patients should be closely monitored for adverse reactions.
