Use Lamictal as directed by your doctor.

- Lamictal has a bitter taste. Do not crush or chew before swallowing. The tablet may be broken in half if your doctor tells you to do so.
- Continue to take Lamictal even if you feel well. Do not miss any dose.
- If you miss a dose of Lamictal, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Lamictal.
