Before Using
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.

Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of levetiracetam oral solution, tablets, or tablets for suspension in children younger than 1 month of age (Keppra®) or in children younger than 4 years of age and weighing less than 20 kilograms (Spritam®, Spritam® tablets for oral suspension), and levetiracetam extended-release tablets in children younger than 12 years of age (Elepsia™ XR) or (Keppra XR®). Safety and efficacy have not been established in these age groups.
Geriatric
