When Doryx is given for one week, it appears to be just as effective as a single-dose of azithromycin (an antibiotic) for chlamydia infections. In fact, clinical studies have continued to show that doxycycline and azithromycin have similar efficacy in curing chlamydia infections. A study of the activity of antibiotics on chlamydia, noted that the use of this medication for several years might be responsible for the high level of resistance to this drug in some regions of the world. When compared with other drugs (azithromycin or fluoroquino-line-type antibiotics) doxycycline showed the least activity on the Chlamydia trachomatis bacterium.

Researchers at the University Hospital for Infectious Diseases in Croatia conducted a study to examine 125 patients with chlamydia and chronic prostate infection. They were given either azithromycin or Doryx. According to researchers, results demonstrated that there was no significant difference between the eradication or cure rates with either drug. However, a physician may prescribe doxycycline to you if you are resistant to other types of antibiotics.
