Before Using This Medicine
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.

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.

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.
