How does it work?

An antibiotic mainly used to treat infections, minocycline has been found to be beneficial in some people with inflammatory arthritis. Exactly why it works is unknown, however some people believe some rheumatoid diseases are caused by a hypersensitivity reaction due to infection of mycoplasmas. If this is indeed the case, mincocycline works by eliminating the mycoplasmas. Others believe the benefit is merely anti-inflammatory.
