This microorganism is usually treated when identified on Pap smear. Trichomonas causes substantial inflammation of the cervix and makes the job of interpreting the Pap smear more difficult.

After treating the patient with Flagyl, the smear should be repeated in about 3-6 months…long enough to allow complete resolution of any lingering inflammation, but sooner than 1 year.

If there is other evidence of a significant cervical lesion (Dysplasia) then the Pap may be repeated sooner after treatment.
