Introduction

Lacosamide is an anti convulsant used to control seizures/fits. It is used with other medicines particularly to treat partial seizures in children/teenagers with epilepsy. 

Medication instructions

How to give Lacosamide

  • It must be prescribed by a doctor. You should never give your child anyone else's medications. 
  • Your doctor will check and make sure that other drugs your child is taking are compatible with Lacosamide. There are some drugs such as Carbamazepine and Phenytoin that should be used with caution. 

  • This is also important if you are giving your child herbal or complementary medicines. The doctor can check to make sure they are compatible. 

  • Tell your doctor if your child has a heart problem. An ECG may need to be done. 

Monitoring and medication levels 

There is no need to do regular blood monitoring with Lacosamide.  

Some doctors may want to do a base-line ECG before starting the medication. This is to ensure there are no prior problems with the electrical conduction of the heart. 

 

What to do if your child vomits

  • If your child vomits within 30 minutes after having their dose, then repeat the dose.
  • If it is longer than 30 minutes since having the dose you do not need to repeat the dose, but if vomiting or diarrhoea continues, seek medical help.

What to do if your child misses a dose

  • If a dose is missed, it should be taken as soon as it is remembered.
  • The next due dose should be taken at the usual time.
  • However, if the missed dose is remembered in close proximity to the next due dose (i.e. within 3 to 4 hours of the next dose), please seek medical advice.
  • If unsure about what to do, the treating GP, epilepsy nurse, paediatrician or neurologist should be contacted.
