What is lacosamide?
Lacosamide is an anti-epileptic drug, also called an anticonvulsant.
Lacosamide is used together with other medications to treat partial-onset seizures in adults and children who are at least 4 years old.
Lacosamide may also be used for purposes not listed in this medication guide.
Do not stop using lacosamide suddenly or you may have increased seizures.
Some young people have thoughts about suicide while taking this medicine. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.
You may feel faint while taking lacosamide. Call your doctor right away if you have fast or pounding heartbeats, shortness of breath, and sudden dizziness.
Before taking this medicine
You should not use lacosamide if you are allergic to it.
To make sure lacosamide is safe for you, tell your doctor if you have ever had:
depression, suicidal thoughts or actions;
drug or alcohol addiction;
nerve problems caused by diabetes; or
phenylketonuria/PKU (lacosamide liquid may contain phenylalanine).
Some people have thoughts about suicide while taking lacosamide. Your doctor will need to check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
Call your doctor if you have new or worsening depression or suicidal thoughts during the first several months of treatment, or whenever your dose is changed.
Follow your doctor's instructions about taking seizure medication if you are pregnant. Seizure control is very important during pregnancy, and having a seizure could harm both mother and baby. Do not start or stop taking this medicine without your doctor's advice, and tell your doctor right away if you become pregnant.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of lacosamide on the baby.
It is not known whether lacosamide passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
Lacosamide is not approved for use by anyone younger than 4 years old.
How should I take lacosamide?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Lacosamide can be taken with or without food.
Measure liquid medicine with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Contact your doctor if your seizures get worse or you have them more often while taking lacosamide.
Wear a medical alert tag or carry an ID card stating that you take lacosamide. Any medical care provider who treats you should know that you take seizure medication.
Use lacosamide regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Do not stop using lacosamide suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
Store at room temperature away from moisture and heat. Do not freeze the liquid form of lacosamide.
Keep track of your medicine. Lacosamide is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
