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 people with epilepsy who are at least 17 years old.
Lacosamide may also be used for purposes not listed in this medication guide.
What is the most important information I should know about lacosamide?
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
What should I discuss with my health care provider before taking lacosamide?
You should not use this medication if you are allergic to lacosamide.
To make sure lacosamide is safe for you, tell your doctor if you have:
a history of depression, suicidal thoughts or actions, or drug or alcohol abuse;
phenylketonuria (PKU; the liquid form of lacosamide may contain phenylalanine);
nerve problems caused by diabetes; or
a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker), heart failure, or other severe heart disorder.
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. Tell your doctor if you are breast-feeding a baby.
Lacosamide is not approved for use by anyone younger than 17 years old.
How should I take lacosamide?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. 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.
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.
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.
Store at room temperature away from moisture and heat. Do not freeze the liquid form of lacosamide.
Keep track of the amount of medicine used from each new bottle. Lacosamide is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking lacosamide?
Lacosamide may cause blurred vision or impair your balance, thinking, or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
