On August 12, 2010, the Food and Drug Administration (FDA) announced that the widely prescribed anti-seizure and bipolar medicine Lamictal (1.4 million prescriptions filled in 2009) can cause inflammation of the membranes covering the brain and spinal cord. The condition, called "aseptic meningitis," refers to inflammation in the absence of bacteria. The FDA will work with drug-maker GlaxoSmithKline to revise the "Warnings and Precautions" section of the Lamictal (generic name: lamotrigine) label accordingly.
Although meningitis is commonly thought to occur because of a bacterial infection, it can also be caused by viruses, chemicals, some vaccines, immune diseases, and, in this case, certain medications. If you are taking Lamictal, look out for the following meningitis symptoms: headache, stiff neck, nausea, vomiting, rash, muscle aches, fever, and sensitivity to light. Depending on the cause, meningitis can be a life-threatening condition.
