Trichomoniasis: What You Need to Know

Trichomoniasis is a common sexually transmitted infection caused by a tiny parasite called Trichomonas vaginalis. It spreads through vaginal sex, and both men and women can catch it, though women usually notice symptoms first.

If you think you might have it, don't panic. Most cases are easy to treat with a short course of medication. The key is to recognize the signs early and get tested.

Typical Signs and Symptoms

Women often experience a frothy, yellow‑green discharge that may have a strong odor. It can also cause itching, burning during urination, or discomfort during sex. Men usually have milder signs—sometimes a thin discharge from the penis or irritation inside the urethra. Some people never notice any symptoms, which is why regular testing is important if you’re sexually active.

Symptoms usually show up within a week to a month after exposure, but they can appear later. If you notice any of these changes, especially a new discharge or irritation, it’s a good idea to see a clinician right away.

How to Get Tested and Treated

Testing is simple. A doctor will take a swab from the vagina, cervix, or urethra and examine it under a microscope or run a rapid DNA test. Results often come back within a day.

The go‑to treatment is a single dose of an antibiotic called metronidazole or tinidazole. Both work well, but you must finish the whole dose even if you feel better. Skipping it can let the infection come back.

Because trichomoniasis can spread back and forth, it’s critical that any sexual partners get treated at the same time. This stops the infection from bouncing between you and your partner.

While on medication, avoid alcohol for at least 24 hours for metronidazole and up to 72 hours for tinidazole. Alcohol can cause nasty nausea, cramps, and vomiting when mixed with these drugs.

After treatment, a follow‑up test isn’t always required if symptoms disappear. However, if you’re pregnant, have a weakened immune system, or keep getting the infection, your doctor may ask for a repeat test to be sure it’s gone.Preventing future infections is straightforward: use condoms consistently, limit the number of sexual partners, and talk openly with partners about STI testing. These steps cut the risk dramatically.

Remember, trichomoniasis isn’t a life‑threatening condition, but it can raise the chance of other infections, like HIV, and cause pregnancy complications. Getting tested, treating promptly, and notifying partners keep you and your loved ones safe.

If you’re unsure whether you need a test, most clinics offer confidential screening without an appointment. It’s quick, often free, and worth the peace of mind.

Bottom line: Spot the symptoms, get tested, take the full dose of medication, and make sure your partners do the same. Simple steps, big impact on your health.
