Doxycycline is generally not recommended for adolescents. Doxycycline is also a broad-spectrum anti-inflammatory drug that can be used for illnesses caused by infections with sensitive Gram-positive cocci and Gram-negative bacilli.Doxycycline is contraindicated in children under the age of 8 years, while children over the age of 8 years can take doxycycline for anti-infective treatments under a doctor’s supervision. However, it is recommended that it is best not to use it when other medications are available because doxycycline belongs to the tetracycline group of medications and there is a possibility that tetracycline teeth may form after taking it. Children’s teeth are at the stage of growth and development, and it is difficult to reverse drug-induced tetracycline, so it is generally not recommended that adolescents take doxycycline if there are other medications to choose from.
