Lamotrigine is an anticonvulsant medication commonly used to treat epilepsy and Bipolar disorder. It works by stabilizing mood and preventing seizures by inhibiting the release of excitatory neurotransmitters in the brain. Lamotrigine is often prescribed as part of a comprehensive treatment plan and may be used alone or in conjunction with other medications. Its side effects can include dizziness, headache, and, in rare cases, serious skin rashes.
