Here is something i hope will help.....i got it from the net....It looks as if the duration of treatment is something like 10 days...
Chlamydia Treatment
Chlamydia can be cured with antibiotics. The recommended chlamydia treatment is either doxycycline (Doryx, Vibramycin, others), 100 milligrams orally twice a day for seven days, or azithromycin (Zithromax), in a new single-dose treatment of 1 gram orally. The effectiveness of the two drugs is the same. You should decide what's best for you: Doxycycline is four times less expensive, but azithromycin is much more convenient. Other treatments include ofloxacin (Floxin), 300 milligrams orally twice a day for seven days, erythromycin (PCE, ERYC, others), 500 milligrams orally four times a day for seven days, or sulfisoxazole (Gantrisin), 500 milligrams orally four times a day for 10 days. Sulfisoxazole treatment is not as effective as the other regimens.
