Key takeaways
Lamotrigine (Lamictal) and desipramine (Norpramin) are both prescription medications, but they are used for different conditions and belong to different drug classes. Lamotrigine is an antiepileptic medication used to treat seizures and bipolar disorder, while desipramine is a tricyclic antidepressant (TCA) used to treat depression. Lamotrigine is available in various forms, including chewable tablets and extended-release tablets, whereas desipramine is typically taken once a day in tablet form. Lamotrigine can cause serious skin reactions and requires a slow dose increase to minimize this risk, while desipramine can cause side effects like sleepiness, confusion, and weight gain. Additionally, desipramine is not a first-choice treatment for depression due to its side effects, whereas lamotrigine is commonly used for its approved conditions. Both medications can interact with other drugs and have specific warnings, such as the risk of suicidal thoughts with lamotrigine and the risk of heart problems with desipramine.
