Read this Medication Guide before you start taking lamotrigine tablets and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment. If you have questions about lamotrigine tablets, ask your healthcare provider or pharmacist.

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 between 2 to 16 years of age 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.  You may or may not have a rash with these types of reactions.  Call your healthcare provider right away if you have any of these symptoms:

frequent infections
severe muscle pain
swelling of your face, eyes, lips or tongue
swollen lymph glands
unusual bruising or bleeding
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:.

thoughts about suicide or dying
attempt to commit suicide
new or worse depression
new or worse anxiety
feeling agitated or restless
panic attacks
trouble sleeping (insomnia)
new or worse irritability
acting aggressive, being angry, or violent
acting on dangerous impulses
an extreme increase in activity and talking (mania)
other unusual changes in behavior or mood

Do not stop lamotrigine tablets without first talking to a healthcare provider.

Stopping lamotrigine tablets suddenly can cause serious problems.
Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.

How can I watch for early symptoms of suicidal thoughts and actions?

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 rarely 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:

stiff neck
unusual sensitivity to light
muscle pains

Meningitis has many causes other than lamotrigine tablets, which your doctor would check for if you developed meningitis while taking lamotrigine tablets.

Lamotrigine tablets can have other serious side effects. For more information ask your healthcare provider or pharmacist. Tell your healthcare provider if you have any side effect that bothers you. Be sure to read the section below entitled "What are the possible side effects of lamotrigine tablets?"

5.   Patients prescribed lamotrigine tablets have sometimes been given the wrong medicine because many medicines have names similar to lamotrigine tablets, so always check that you receive lamotrigine tablets.

Taking the wrong medication can cause serious health problems. When your healthcare provider gives you a prescription for lamotrigine tablets:

Make sure you can read it clearly.
Talk to your pharmacist to check that you are given the correct medicine.
Each time you fill your prescription, check the tablets you receive against the pictures of the tablets below.

These pictures show the distinct wording, colors, and shapes of the tablets that help to identify the right strength of lamotrigine tablets. Immediately call your pharmacist if you receive a lamotrigine tablet that does not look like one of the tablets shown below, as you may have received the wrong medication.
