What dose of erythromycin cures STDs?

One gram of azithromycin (Zithromax, Z-max, Z-Pack) in a single dose cures uncomplicated chlamydia found on screening, but different doses and medications are used for other types of chlamydia. You can get this dose with four 250 mg pills, two 500 mg pills, or the 1g powder envelope.

Even though you take it just once, you must abstain from oral, anal, and vaginal sex; genital-genital contact; and sharing sex toys for one week after treatment to avoid passing it on to a partner before the antibiotic has time to do its work. Don't even have sex with a condom -- no contact.
