Moxifloxacin is a quinolone antibiotic, like
ciprofloxacin, levofloxacin, and others.
Gonorrhea resistant to the quinolones is spreading rapidly, especially in gay men. (You don't say the sex of your partner, so I don't know your orientation.) However, many strains remain susceptible. But I doubt you have gonorrhea, so it's probably not relevant. Some quinolones are active against chlamydia, others not--but as I said, chlamydia isn't an issue.
