The most common route for medication administration in pediatric patients is oral. This method is preferred because it is generally more convenient and less invasive for children compared to other routes. Oral medications can be easily administered in the form of liquids, tablets, or chewable tablets, which can make them more palatable and easier for children to take. Additionally, oral administration allows for safer dosing adjustments and monitoring of absorption.

Other routes such as intravenous administration are often reserved for more critical situations requiring rapid medication effect or for patients who cannot swallow or absorb medications adequately. Sublingual and rectal routes are less common due to the potential for improper dosing and discomfort in children. Therefore, oral administration is favored for its simplicity and effectiveness in pediatric care.
