Key takeaways
Lamotrigine (Lamictal) and aripiprazole (Abilify) 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 I disorder, while aripiprazole is an atypical antipsychotic used for schizophrenia, bipolar I disorder, and as an add-on for depression. Lamotrigine is available in various forms, including immediate-release and extended-release tablets, and can cause serious skin reactions like rash. Aripiprazole, on the other hand, is available in tablets, solutions, and orally disintegrating tablets, and can cause side effects like movement problems and sleep issues. While both medications can cause dizziness and have serious side effects, aripiprazole is more likely to cause weight gain and high blood sugar. Lamotrigine requires careful dose adjustments to avoid severe skin reactions, whereas aripiprazole can take several weeks to show full effects and may cause impulse-control problems. Both medications are available in generic forms.
