Lamotrigine Tapering Guidelines

General Principles

The Centers for Disease Control and Prevention, as per MMWR Recommendations and Reports, recommends slow tapering to increase overall outcomes and minimize withdrawal symptoms 1
For patients who have been taking medications for longer durations (≥1 year), tapers of 10% per month or slower are likely to be better tolerated than more rapid tapers 1
Tapering should be individualized based on patient response, with frequent monitoring (at least monthly) during the process 1

For lamotrigine 25mg, consider reducing by 5mg (20%) every 2-4 weeks 1
For patients on long-term therapy (≥1 year), consider an even slower taper, reducing by 2.5mg (10%) every 4 weeks 1

Follow up frequently (at least monthly) with patients during the tapering process 1
Monitor for withdrawal symptoms after each dose reduction before proceeding to the next step 1
Clinically significant withdrawal symptoms may signal the need to further slow the taper rate 1
Maximize non-pharmacologic treatments for symptom management during tapering 1
If severe withdrawal symptoms occur, return to the previous well-tolerated dose and slow the taper further 1

Tapers might need to be paused and restarted when the patient is ready 1
After reaching the smallest available dose (5mg for lamotrigine), the interval between doses can be extended (every other day, then every third day) before complete discontinuation 1

Avoid tapering too quickly, which may increase risk of withdrawal symptoms 1
Remain alert for signs of anxiety, depression, or other mental health concerns that might emerge during the tapering process 1
Discuss with patients the importance of not abruptly stopping medication, as this can increase risk of adverse effects 1
