Drug information provided by: Micromedex

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 this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of lamotrigine chewable tablets, disintegrating tablets, or tablets in children with certain types of seizures older than 2 years of age. However, safety and efficacy have not been established in children less than 2 years of age.

Appropriate studies have not been performed on the relationship of age to the effects of lamotrigine extended-release tablets in children with partial seizures younger than 13 years of age. Safety and efficacy have not been established.

Appropriate studies have not been performed on the relationship of age to the effects of lamotrigine chewable tablets, disintegrating tablets, or tablets in children with bipolar disorder. Safety and efficacy have not been established.

Geriatric

Although appropriate studies on the relationship of age to the effects of lamotrigine have not been performed in the geriatric population, geriatric-specific problems are not expected to limit the usefulness of lamotrigine in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require an adjustment in the dose for patients receiving lamotrigine.
