Infected women who are sexually active have a high rate of reinfection. Rescreening sexually active women at 3 months posttreatment has been reviewed and studied and is recommended. [48, 132] Evidence is currently insufficient to support a similar recheck in male patients, but it may be undertaken at physician discretion.

Because trichomoniasis has a high rate of comorbidity with other STIs, providers should consider empiric treatment of infections that frequently coexist with trichomoniasis, such as gonorrhea and chlamydia. Patients should be advised to follow up on results of other studies performed.

If symptoms persist despite pharmacotherapy, patients should follow up with their primary care providers. Persistent treatment failures may require metronidazole susceptibility testing through the CDC.

Sexual partners of patients infected with trichomoniasis must be treated to prevent reinfection. Patient and sexual partners should abstain from sexual intercourse until they have both completed therapy and are asymptomatic. [57] In areas where it is legal, expedited partner therapy may be useful in efficiently treating all sexual partners of the patient. [14]
