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.
2. Other serious reactions, including serious blood problems or liver problems. Lamotrigine tablets can also cause other types of allergic reactions or serious problems that may affect organs and other parts of your body like your liver or blood cells.

- frequent infections

- weakness, fatigue
- yellowing of your skin or the white part of your eyes
3. Like other antiepileptic drugs, lamotrigine tablets may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.
Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:

How can I watch for early symptoms of suicidal thoughts and actions in myself or a family member?
- Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings.
- Keep all follow-up visits with your healthcare provider as scheduled.
- Call your healthcare provider between visits as needed, especially if you are worried about symptoms.
4. Lamotrigine tablets may cause aseptic meningitis, a serious inflammation of the protective membrane that covers the brain and spinal cord.
Call your healthcare provider right away if you have any of the following symptoms:
