Patients who are HIV-positive should generally receive the same treatment as those who are HIV negative. The notable exception is that the multiday treatment drug regimen (metronidazole 500 mg twice daily for 7 days) was recently shown to be more effective in treating T vaginalis in HIV-positive women than a single-dose treatment (metronidazole 2 g single dose). [109] Thus, the CDC recommends considering the multidose treatment in HIV-positive women with trichomoniasis. [48] The CDC also recommends rescreening at 3 months after the completion of therapy for HIV-positive women due to the likelihood of recurrent or persistent infection and the increased risk of HIV transmission with comorbid trichomoniasis. [48, 49, 110, 111]
