Which antibiotic should be avoided in the pediatric population?

Tetracycline should be avoided in the pediatric population due to its potential to cause dental staining and negatively affect bone development. Tetracyclines can bind to calcium ions, leading to a complex that becomes incorporated into growing teeth and bones. This may result in permanent discoloration of teeth that have yet to emerge and can also impact bone growth.

In contrast, penicillin, amoxicillin, and cephalexin are generally considered safe and effective for use in children. They are commonly used to treat various bacterial infections in the pediatric population without the same risks associated with tetracycline. Thus, the caution surrounding the use of tetracycline in younger patients is primarily linked to its adverse effects on dental and skeletal health.
