What is a common side effect of tetracyclines in children?

Tetracyclines are a class of antibiotics commonly used to treat a variety of infections. One significant side effect of this class of drugs, particularly in children younger than eight years old, is tooth discoloration. Tetracyclines can bind to calcium in developing teeth, leading to a characteristic yellow or brown discoloration and potentially impacting enamel development. This side effect is particularly concerning because it occurs during a critical period of dental development in children, making it a key consideration when prescribing these antibiotics to young patients.

The other options referenced do not have the same established association with tetracycline use in children. Hearing loss, gastroparesis, and cardiomyopathy are not recognized as common or direct side effects of tetracyclines in this population. Understanding the implications of tetracycline use, especially regarding children’s dental health, is crucial for healthcare providers to prevent long-term aesthetic and functional dental issues.
