Key takeaways
Lamotrigine (Lamictal) and quetiapine (Seroquel) are both prescription medications, but they are used for different conditions and belong to different drug classes. Lamotrigine is an antiepileptic used to treat seizures and bipolar disorder, while quetiapine is an atypical antipsychotic used for schizophrenia, bipolar disorder, and as an add-on for depression. Lamotrigine is available in various forms, including immediate-release and extended-release tablets, and it can cause serious skin reactions like rash. Quetiapine, on the other hand, is available in immediate-release and extended-release forms and can cause weight gain, high blood sugar, and cholesterol levels. Both medications require careful dose adjustments and have significant side effects, but quetiapine is more likely to cause drowsiness. Lamotrigine interacts with many medications, such as birth control pills, while quetiapine should be avoided in older adults with dementia-related psychosis.
