Is it possible for you to use a double dose of dtap infantrix in adults?

Dr. Keith Ramsey answered

Specializes in Pediatrics - Adolescent Medicine

No: The adult tdap is actually a lower dose of antigen than that the dtap used in babies and younger children. It is thought that the dose has to be lower for older children and adults to avoid high fevers and possible seizures.
