This article is for those being treated with antibiotics for trichomoniasis. The most common antibiotic treatments are Flagyl (Metronidazole) or Tinidazole. These antibiotics do not treat other sexually transmitted infections. It is important to remember when taking these antibiotics to avoid drinking alcohol as it can cause a severe and unpleasant reaction. Please follow the instructions your doctor provided and complete the entire course of medication.

See a doctor in person if…

You develop high fever, severe abdominal pain, or persistent vomiting

Check-in with K Health if…

Your symptoms improve but do not completely resolve as this could be a sign of a partially treated infection. In this case your doctor may want to adjust your treatment or order further testing.

To-do list

  • Take the antibiotics as directed
  • Avoid all sexual activity until your symptoms have resolved and for at least one week after treatment
  • Contact your sexual partner(s) so they can be tested and treated
  • Get re-tested in three months to ensure the infection has cleared

What is trichomoniasis?

Trichomoniasis is a very common sexually transmitted disease (STD), and in the United States, about 3.7 million people are infected with it. Many people are infected but are asymptomatic. Trichomoniasis is caused by a tiny parasite called Trichomonas vaginalis (TV). You can catch it through genital contact. Infection is more common in women than in men. In women, the lower genital tract (vulva, vagina, cervix, and urethra) are the parts most affected. In men, it’s the inside of the penis (urethra).

Where to get tested for STDs

If you’re sexually active, you should consider STD testing an important part of your overall health plan. STDs are common and contagious, but sometimes asymptomatic—meaning you can contract an STD and pass it to others without even realizing it. STDs can cause long-term health consequences for both patients and their sexual partners if left untreated. Early detection and treatment is critical.

STD prevention

There are many definitions of safe sex. Some define it as sexual contact in which bodily fluids like blood, semen, or vaginal fluids are not exchanged. Others define it as sexual contact between two monogamous partners who have each been tested for STDs and each have none. A more general understanding of safe sex is sex using a barrier method of protection against STDs and unplanned pregnancy. Some sexual health professionals prefer the term “safer sex,” to “safe sex,” as all sex carries some risk, whether it be of infection and/or pregnancy, even if precautions are taken. There is no guaranteed way to avoid STDs without abstaining from sexual contact. However, here are some guidelines for safer sex that offer the most protection against STDs and unwanted pregnancy.
