Drug Dosing Issues and Resources

The designation of post-gestational age can differ among sources. In Lexi-Comp's pediatric database this is determined from the first day of the last menstrual period until the birth of the baby. Because this is not equivalent to the date of conception there is obviously some degree of variability. Pediatric dosing calculations are frequently based on this parameter. This represents one of the key dosing precautions in premature infants. In addition, clinical guidelines may be based on this age.
