Trichomoniasis Follow-up
- Author: Darvin Scott Smith, MD, MSc, DTM&H; Chief Editor: Burke A Cunha, MD more...
Further Outpatient Care
- Sexual partners of patients infected with trichomoniasis must be treated to prevent reinfection.
- Consider empiric treatment of other sexually transmitted infections that frequently coexist with trichomoniasis.
- Advise the patient to abstain from sexual intercourse until both the patient and partner have completed therapy and are asymptomatic.[2]
- Persistent treatment failures may require metronidazole susceptibility testing through the Centers for Disease Control and Prevention (CDC).
Deterrence/Prevention
- Abstinence from sexual intercourse prevents trichomoniasis.
- Limiting the number of sexual partners decreases the risk of trichomoniasis.
- Male condoms can protect against the transmission of trichomoniasis. Although the efficacy of female condoms is undefined, they may also provide some protection.[2]
- Diaphragms have been shown to protect against trichomoniasis but should not be used as the primary source of protection against HIV.[2]
- Spermicides that contain nonoxynol-9 are not recommended for the prevention of sexually transmitted diseases. Frequent use is associated with disruption of the genital epithelium, which may be associated with an increased risk of HIV infection and other sexually transmissible agents.[2]
Complications
- See Mortality/Morbidity.
Patient Education
- Persons with trichomoniasis who notify their partner of their infection help disrupt the transmission of trichomoniasis and other sexually transmitted diseases.[2]
- Discuss the side effects and interactions encountered with metronidazole and other nitroimidazole drugs.
- Education concerning sexually transmitted disease treatment and sexually transmitted infection prevention should be provided (see Deterrence/Prevention).
