Tetracycline affects children from what age?

  1. 14 weeks in utero to 8 yrs old

  2. Birth to 5 yrs old

  3. 6 months to 10 yrs old

  4. 1 yr to 12 yrs old

The correct answer is: 14 weeks in utero to 8 yrs old

Tetracycline, an antibiotic, can affect children from 14 weeks of development in utero up until 8 years of age. This is because tetracycline can interfere with the development of the teeth and bones in children, causing permanent discoloration and deformities. It is not recommended for use in children under 8 years old and should only be used if it is the only option available. Birth to 5 years of age is too broad of a range as tetracycline is not recommended for infants. Similarly, 6 months to 10 years old is also too broad as tetracycline should not be used in children over 8 years old. 1 year to 12 years of age is also incorrect as tetracycline use should be limited to children under 8 years old.
