Common questions about Motpoly XR (lacosamide)
Yes, Motpoly XR (lacosamide) is a schedule 5 controlled substance (C-V). This means it has a potential risk of misuse. It also has a risk of causing physical dependence if you take it for a long time. Because it's a controlled substance, there are federal and state laws about how Motpoly XR (lacosamide) is prescribed and filled. To help lower the risk of misuse and dependence, take Motpoly XR (lacosamide) as prescribed. Ask your prescriber or pharmacist if you have questions about what it means for the medication to be a controlled substance.

For example, they could consider switching you to the liquid form of immediate-release lacosamide (Vimpat).

It takes a little less than 3 days for most of Motpoly XR (lacosamide) to leave your body after one dose. This estimate comes from the medication's half-life. The timing might be different for people with kidney or liver problems. This is because these organs help remove the medication from your system. Even though it can take a few days to clear from your body, it’s important to take Motpoly XR (lacosamide) every day exactly as prescribed. This keeps the medication level stable in your body so it can control your seizures. Ask your prescriber if you have any questions about how long the medication stays in your system.
Motpoly XR and Vimpat are both versions of the anti-seizure medication lacosamide. Motpoly XR is an extended-release capsule. It's taken once a day and must be swallowed whole.

Vimpat is approved for people 1 month of age and older with partial-onset seizures. It's also for people 4 years and older with primary generalized tonic-clonic (PGTC) seizures. Motpoly XR is for adults and children weighing at least 110 lbs for both types of seizures. Ask your prescriber to help you compare and see which best fits your needs.
