What is doxycycline?
Doxycycline is used to treat many different bacterial infections, such as acne, urinary tract infections , intestinal infections, respiratory infections, eye infections, gonorrhea , chlamydia , syphilis, periodontitis (gum disease), and others. Doxycycline works by stopping the growth of bacteria when treating bacterial infections and is also thought to have an anti-inflammatory action when used for other conditions. Doxycycline is a tetracycline antibiotic .
Some forms of doxycycline are used to prevent malaria, to treat anthrax, or to treat infections caused by mites, ticks, or lice.
You should not take doxycycline if you are allergic to any tetracycline antibiotic.
Children younger than 8 years old should use doxycycline only in cases of severe or life-threatening conditions. This medicine can cause permanent yellowing or graying of the teeth in children.
Using doxycycline during pregnancy could harm the unborn baby or cause permanent tooth discoloration later in the baby’s life.
