What is the most important information I should know about lamotrigine tablets?
1. Lamotrigine tablets may cause a serious skin rash that may cause you to be hospitalized or even cause death.
There is no way to tell if a mild rash will become more serious. A serious skin rash can happen at any time during your treatment with lamotrigine tablets, but is more likely to happen within the first 2 to 8 weeks of treatment. Children and teenagers aged between 2 and 17 years have a higher chance of getting this serious skin rash while taking lamotrigine tablets.

- The risk of getting a serious skin rash is higher if you:
- •

- •
- take a higher starting dose of lamotrigine tablets than your healthcare provider prescribed.
