Why is doxycycline contraindicated in pregnancy and in children under 8 years old?

Explanation:
Doxycycline is a tetracycline that binds to calcium and becomes incorporated into mineralizing tissues. During pregnancy and in early childhood, teeth and bones are still developing, so doxycycline can cause permanent discoloration of teeth and enamel defects, and may affect bone growth. This is why it is avoided in pregnant people and in children under 8 years old. Other listed risks, like neural tube defects, pulmonary fibrosis, or vitamin K interference, are not characteristic effects of doxycycline, so they don’t explain the contraindication.
