Among tetracyclines, which side effect is most clearly associated with bone development retardation?

• A. Blue sclera
• B. Bone growth retardation
• C. Whorl Keratopathy
• D. Punctate conjunctival changes

Answer: (B)

Tetracyclines can chelate calcium and become deposited in calcifying tissues such as bone and teeth. In developing individuals, this interference with mineralization leads to impaired bone growth, making bone growth retardation the most direct and clearly linked side effect. The other options aren’t typical tetracycline-related bone effects: blue sclera is not a common tetracycline finding and is more associated with other conditions; whorl keratopathy and punctate conjunctival changes are ocular changes linked to other drugs rather than tetracyclines. So the best answer is the one that directly points to retardation of bone development.
