Quick Answer

Trichomoniasis is treated with a single oral dose of metronidazole or tinidazole, both of which cure the infection. Sexual partners must also be treated to prevent reinfection. A follow-up test is recommended three months after treatment to confirm the cure and check for re-infection.

  • Metronidazole given as a single 2-gram dose is the preferred treatment.
  • Tinidazole is an equally effective alternative with fewer side effects for some people.
  • Treatment is the same for infections in the vagina, cervix, urethra, or rectum.
  • Without treating sexual partners, reinfection is very likely.
  • Testing for cure is recommended about three months after completing treatment.
  • Metronidazole is also used to treat bacterial vaginosis when both infections occur together.

The Landscape

Trichomoniasis is caused by the parasite Trichomonas vaginalis, which infects the genital and urinary tracts. Because it is a parasitic infection, it responds well to specific antiprotozoal antibiotics that kill the organism directly. The goal of treatment is elimination of the parasite with oral medication, which also reduces the risk of spreading the infection to others. Prompt treatment is important because untreated trichomoniasis can increase susceptibility to other sexually transmitted infections and can cause complications during pregnancy.

Treatment Windows by Infection

Bacterial infections clear with antibiotics measured in days: a single 500 mg intramuscular ceftriaxone dose for gonorrhea (doxycycline is added only if chlamydia has not been ruled out), seven days of doxycycline for chlamydia, penicillin injections for syphilis staged by duration. Viral infections play a longer game — suppressive antivirals for herpes, daily ART driving HIV to undetectable, and 8–12-week antiviral courses curing over 95% of hepatitis C cases.
