However, there are some exceptions, when your doctor may advise you to give it thrice a day. Please follow your doctor’s advice in such conditions.

It should ideally be given at the same time every day to establish a routine as it decreases the chances of missing a dose.

What if I miss the dose?

Never give a double dose of Lacosamide .

If your child vomits the contents of medicine within 30 minutes of taking a dose,then you can give the dose again; but if your child vomits after 30 minutes of taking the dose, then leave him be and do not give it again.

How much of the drug should I give ideally?

Your doctor will work out the right amount of Lacosamide (the dose) for your child and write it in your prescription.

When you first start giving Lacosamide to your child, you will give them a small amount and then increase the dose little by little over a course of few days or weeks. This will help your child’s body to get use to the medicine. Your doctor will give you the directions.

It is non-negotiable to follow your doctor’s instructions as to how much of the dosage should be given at what interval.

When your child is free of seizures or convulsions (fits) and has no obvious side effects, you will know that the dosage is just correct.
