Lacosamide Injection

Lacosamide injection is used to control partial onset seizures (seizures that involve only one part of the brain) in adults and children 1 month of age and older who cannot take oral medications. Lacosamide injection is also used in combination with other medications to control primary generalized tonic-clonic seizures (formerly known as a grand mal seizure; seizure that involves the entire body) in adults and children 4 years of age and older who cannot take oral medications. Lacosamide injection is in a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain.

🔔 How should this medicine be used?

Lacosamide injection comes as a solution (liquid) to be given intravenously (into a vein). It is usually injected slowly over a period of 30 to 60 minutes in children and adults, or over 15 minutes in adults if necessary. It is usually given twice a day in children or adults or 3 times daily for children weighing 6 kg (13 pounds) or less for as long as you are unable to take lacosamide tablets, extended-release capsules, or oral solution by mouth.

You may receive lacosamide injection in a hospital or you may use the medication at home. If you will be using lacosamide injection at home, your health care provider will show you how to infuse the medication. Be sure that you understand these directions, and ask your health care provider if you have any questions. Ask your health care provider what to do if you have any problems infusing lacosamide injection.

Your doctor will probably start you on a low dose of lacosamide and gradually increase your dose, not more often than once a week.

Lacosamide may help control your condition but will not cure it. It may take a few weeks or longer before you feel the full benefit of lacosamide. Continue to use lacosamideeven if you feel well. Do not stop using lacosamide without talking to your doctor, even if you experience side effects such as unusual changes in behavior or mood. If you suddenly stop using lacosamide, your seizures may happen more often. Your doctor will probably decrease your dose gradually.
