A study from Sweden shows why venereal diseases are often difficult to cure. The authors showed that almost 70 percent of people infected with mycoplasma were not cured by doxycycline, but all were cured with azithromycin.

Doxycycline is the first line antibiotic to treat many venereal diseases, including the most common one called chlamydia. People with venereal diseases are difficult to cure because they often fail to take their medication as long as they were told, or they go back to the same partners who gave them the venereal disease in the first place.

Anyone with burning on urination, a feeling like they have to urinate all the time and urgency when their bladders are full should be checked for venereal diseases. Even if no laboratory test reveals a cause, symptomatic people exposed to a venereal disease should be treated at least with a long-acting erythromycin-type antibiotic.
