I absolutely cannot stomach antibiotics it seems, throw up every time. now i need to treat chlamydia. can a hospital do iv infusion of azithromycin?

Probably unnecessary: This probably could be done, but maybe unnecessary. You only need to take a single dose (1 g), and if taken with food you probably will tolerate it OK. And not all antibiotics cause GI problems; other options are doxycycline and levofloxacin for a week; both usually are well tolerated. The top priority of course is for adequate chlamydia treatment, even at cost of nausea for a day or two.
