Lamotrigine Tablets, USP
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 lamotrigine tablets while taking valproate (valproic acid or divalproex sodium).
- take a higher starting dose of lamotrigine tablets than your healthcare provider prescribed.
- increase your dose of lamotrigine tablets faster than prescribed.
Call your healthcare provider right away if you have any of the following:
- a skin rash
- blistering or peeling of your skin
- painful sores in your mouth or around your eyes
These symptoms may be the first signs of a serious skin reaction. A healthcare provider should examine you to decide if you should continue taking lamotrigine tablets.

3. Like other antiepileptic drugs, lamotrigine tablets may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.
