Overview
Antimicrobial therapy is the standard of care for trichomoniasis in both genders once the diagnosis has been confirmed. The symptoms of trichomoniasis among infected men may disappear within a few weeks even without treatment, but asymptomatic men may continue to be infectious and should therefore be treated. Antimicrobial therapy generally includes either metronidazole or tinidazole 2 g PO in a single dose. Prolonged therapy for 7 days is indicated among patients who fail to respond to the initial course of therapy. Following successful treatment, individuals may still be susceptible to re-infection.
Medical Therapy
Antimicrobial therapy is the standard of care for trichomoniasis in both genders once the diagnosis has been confirmed.[1][2][3] The symptoms of trichomoniasis in infected men may disappear within a few weeks even without treatment, but asymptomatic men may continue to be infectious and should therefore be treated.
Antimicrobial Regimen
- 1. T. vaginalis infection in adults[4]
- Preferred regimen (1): Metronidazole 2 g PO in a single dose
- Preferred regimen (2): Tinidazole 2 g PO in a single dose
- Alternative regimen: Metronidazole 500 mg PO bid for 7 days
- Note: Patients should avoid sexual contact until they are fully cured of trichomoniasis
- 2. T. vaginalis infection in pregnant and lactating Women
- 2.1 Pregnant women
- Preferred regimen: Metronidazole 2 g PO in a single dose
- 2.2 Post-partum and Breastfeeding
- Preferred regimen (1): Metronidazole 2 g PO in a single dose
- Preferred regimen (2): Tinidazole 2 g PO in a single dose
- Note (1): Do not breastfeed for 12-24 hrs following Metronidazole and 72 hrs following Tinidazole
- Note (2): Symptomatic pregnant women, regardless of pregnancy stage, should be tested and considered for treatment.[5] Pregnant women should be advised of the risk and benefits to treatment as infection (definitely) and treatment (possibly)
- Note (3): Pregnant women with HIV who are treated for T. vaginalis infection should be retested 3 months after treatment.
- 3. T. vaginalis infection in patients with HIV
- Preferred regimen: Metronidazole 500 mg PO bid for 7 days
- 4. Persistent or recurrent trichomoniasis
- 4.1 Treatment failure, first-time
- Preferred regimen: Metronidazole 500 mg PO bid for 7 days
- 4.2 Treatment failure, second-time
- Preferred regimen (1): Metronidazole 2 g PO for 7 days
- Preferred regimen (2): Tinidazole 2 g PO for 7 days
- 4.3 Nitroimidazole-resistant T. vaginalis
- Antibiotic susceptibility testing recommended
- Preferred regimen: Tinidazole 2-3 g PO for 14 days[6][7]
- Alternative regimen: Tinidazole 2-3 g PO for 14 days in combination with intravaginal tinidazole[3]
Treatment of Sexual Partners
- Sexual partners of patients with trichomoniasis should be treated.[3][8]
- Patients and their sexual partners should avoid sexual contact until they are fully cured of trichomoniasis.
Follow-up
- Patients should be re-evaluated at the end of the antimicrobial therapy regimen to determine whether therapy has been successful.
- Patients should be instructed that they are still susceptible to re-infection.
- Retesting is recommended for sexually active women within 3 months of treatment for initial infection.[9]
