Key takeaways
Carbamazepine (Tegretol) and Vimpat (lacosamide) are both antiepileptic medications used to treat seizures, but they have some key differences. Carbamazepine is used for various types of seizures, trigeminal neuralgia, and bipolar I disorder (Equetro brand only), while Vimpat is used for partial-onset seizures and as an add-on for primary generalized tonic-clonic seizures. Carbamazepine is available in many forms, including pills, chewable tablets, and liquid, and is not a controlled substance. In contrast, Vimpat is a Schedule V controlled substance, meaning it has a potential for misuse and dependence. Carbamazepine works by blocking sodium channels in the brain, whereas Vimpat's exact mechanism is unclear but is thought to slow sodium channel activity. Common side effects of carbamazepine include dizziness, sleepiness, and stomach upset, while Vimpat can cause dizziness, headache, and nausea. Additionally, carbamazepine can interfere with hormonal birth control and requires routine blood tests, whereas Vimpat does not have these specific concerns.
