  • Pain during urination and sexual intercourse
  • In men: Slight discharge from the penis
  • Burning after urination or ejaculation

How soon after exposure should I get tested for Trichomonas?

Testing for Trichomonas is recommended if you develop symptoms or if your sexual partner has been diagnosed with it. The best time to get tested is at least a week after potential exposure to ensure accurate results. Because many people don’t show symptoms, routine screenings are important, especially for sexually active women.

What is the treatment for Trichomonas?

Trichomoniasis is typically treated with a single dose of an oral antibiotic, usually either metronidazole or tinidazole. These antibiotics are effective and can quickly clear the infection. It’s important for sexual partners to be treated simultaneously to prevent reinfection. Abstinence from sexual activity until completion of the treatment and symptoms resolve is recommended.

How can I protect myself from Trichomonas?

Preventing Trichomonas involves practicing safer sex. This includes using condoms every time you have sex, limiting the number of sexual partners, and having regular STI screenings, especially if you have multiple partners. Maintaining open communication with sexual partners about STI testing and status is also important for prevention.
