doxycycline 20 mg
Doxycycline belongs to the group of medications called tetracyclines. It is used, in addition to dental treatment, to treat adults with periodontitis (inflammation and infection of the tissues, such as ligaments and bones, which support the teeth). Although doxycycline is typically used as an antibiotic, experts believe that doxycycline 20 mg helps periodontitis by slowing the breakdown of collagen, a protein that helps connect and support other tissues in the body.
