Lacosamide is available only with your doctor's prescription.
Before Using lacosamide
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For lacosamide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to lacosamide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of lacosamide injection in children younger than 17 years of age. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of lacosamide injection in the elderly. However, elderly patients are more likely to have age-related heart, kidney, or liver problems, which may require caution in patients receiving lacosamide injection.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Proper Use of lacosamide
A nurse or other trained health professional will give you lacosamide in a hospital. Lacosamide is given through a needle placed in one of your veins. The medicine must be injected slowly, so your IV tube will need to stay in place for 15 to 60 minutes.
Your doctor may give you a few doses of lacosamide until your condition improves, and then you may be switched to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.
Lacosamide should come with a Medication Guide. It is very important that you read and understand this information. Ask your doctor if you have any questions.
Precautions While Using lacosamide
Your doctor will check your progress closely while you are receiving lacosamide. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it.. Blood tests may be needed to check for unwanted effects.
If you develop any unusual or strange thoughts and behavior while receiving lacosamide injection, be sure to discuss it with your doctor. Some changes that have occurred in people receiving lacosamide are like those seen in people who drink too much alcohol. Other changes might be confusion, worsening of depression, hallucinations (seeing, hearing, or feeling things that are not there), suicidal thoughts, and unusual excitement, nervousness, or irritability.
Lacosamide may cause blurred vision, double vision, clumsiness, unsteadiness, dizziness, drowsiness, sleepiness, or trouble with thinking. Make sure you know how you react to lacosamide before you drive, use machines, or do anything else that could be dangerous if you are not alert or able to think or see well. If these side effects are especially bothersome, check with your doctor.
Lacosamide can cause changes in heart rhythms, such as a condition called PR prolongation. It may change the way your heart beats and cause lightheadedness, fainting, or serious side effects in some patients. Contact your doctor right away if you have any symptoms of heart rhythm problems, such as fast, slow, or irregular heartbeats.
