Lamotrigine is an anticonvulsant medication used to treat seizures in epilepsy and bipolar disorder. It works by decreasing the abnormal activity in the brain that causes seizures. Lamotrigine is available in tablet form and is typically taken once or twice a day. The dosage and duration of treatment will depend on the individual's medical condition and response to the medication. Lamotrigine may cause side effects such as dizziness, headache, nausea, blurred vision, and rash. It may also increase the risk of suicidal thoughts and behaviors, especially in children, teenagers, and young adults. Therefore, it is important to closely monitor patients taking lamotrigine and promptly report any concerning symptoms to a healthcare provider.
