Oxytetracycline was the second of the broad-spectrum tetracycline group of antibiotics to be discovered.
Oxytetracycline is still used to treat infections caused by chlamydia (e.g. the chest infection psittacosis, the eye infection trachoma, and the genital infection urethritis) and infections caused by mycoplasma organisms.
Oxytetracycline is used to treat acne, due to its activity against the bacteria on the skin that cause acne (Propionebacterium acnes). It is used to treat flare-ups of chronic bronchitis, due to its activity against the bacteria usually responsible, Haemophilus influenzae.
Oxytetracycline may also be used to treat other rarer infections, such as those caused by a group of micro-organisms called rickettsiae (e.g. Q fever). To make sure the bacteria causing an infection are susceptible to oxytetracycline your doctor may take a tissue sample, for example a swab from the infected area, or a urine or blood sample.
