Trichomoniasis, commonly called "trich," is a sexually transmitted infection caused by a parasite called Trichomonas vaginalis, affecting the urogenital tract and causing symptoms primarily in women though men can also be infected. Many people confuse trichomoniasis with yeast infections or bacterial vaginosis, or don't realize it's an STI. Trichomoniasis is caused by a parasite and produces frothy, yellow-green vaginal discharge with a strong odor, itching, and discomfort, whereas yeast infections are caused by fungus and produce thick white discharge, and bacterial vaginosis involves bacterial imbalance with thin grayish discharge, though symptoms can overlap and testing is needed for accurate diagnosis.
Trichomoniasis can cause uncomfortable symptoms such as frothy, yellow-green vaginal discharge with a strong, unpleasant odor (in women), itching, burning, or redness of the genitals, discomfort during urination or intercourse, and in men, mild discharge, irritation inside the penis, or burning after urination or ejaculation, though many men have no symptoms.
Getting the right treatment plan for trichomoniasis can help cure the infection, relieve symptoms, prevent transmission to sexual partners, and reduce the risk of complications like increased susceptibility to other STIs or pregnancy complications.
With LifeMD, you can get immediate help and treatment online without an in-office appointment. Prescription antibiotics can cure trichomoniasis quickly, typically with a single dose or short course of medication.

Metronidazole is an antibiotic that works by damaging the DNA of the Trichomonas parasite, killing it and curing the infection. The standard treatment is a single dose of two grams (four 500 mg pills) taken all at once, which cures the infection in about 85-95% of cases. It's convenient, highly effective, and most people experience symptom relief within a few days. Both sexual partners must be treated simultaneously to prevent reinfection. Alcohol must be avoided for at least 24 hours after taking metronidazole to prevent severe nausea and vomiting.
Metronidazole can also be prescribed as 500 mg taken twice daily for seven days, which has a slightly higher cure rate (about 90-95%) than the single dose and may be preferred for certain cases or if the single dose fails. The seven-day course provides sustained medication levels and may be better tolerated by some people. It requires consistent adherence to complete the full course even if symptoms improve. Alcohol must be avoided during treatment and for at least 24 hours after the last dose.
Tinidazole is an antibiotic similar to metronidazole that works by killing the Trichomonas parasite through DNA damage. It's typically given as a single dose of two grams (four 500 mg pills) and has cure rates similar to or slightly better than metronidazole (86-100%). Some people tolerate tinidazole better with fewer side effects like nausea or metallic taste. It's a good alternative if metronidazole causes significant side effects or if treatment fails. Alcohol must be avoided for at least 72 hours after taking tinidazole to prevent severe reactions.

Yes, both men and women can get trichomoniasis, though symptoms and complications differ between sexes. Women are more likely to experience noticeable symptoms including frothy discharge, strong odor, itching, and discomfort. The infection affects the vagina, urethra, and cervix. Men often have no symptoms or only mild symptoms like slight discharge from the penis, irritation inside the penis, or mild burning during urination or ejaculation. The infection affects the urethra and sometimes the prostate. Despite often being asymptomatic in men, they can still transmit the infection to partners. This is why treating both partners simultaneously is essential – even if a male partner has no symptoms, he needs treatment to prevent reinfecting his partner and to clear his own infection.
Trichomoniasis lasts indefinitely without treatment – it doesn't go away on its own. The parasite will continue to live in the urogenital tract and can be transmitted to sexual partners even when symptoms are mild or absent. With proper antibiotic treatment, trichomoniasis is cured quickly. Most people feel symptom relief within a few days to a week of treatment, and the infection is typically eliminated completely. However, reinfection is common if sexual partners aren't treated simultaneously or if unprotected sex occurs with new or untreated partners. After successful treatment, there's no lasting immunity – you can get trichomoniasis again if exposed.
Yes, trichomoniasis is completely curable with proper antibiotic treatment. A single dose or short course of metronidazole or tinidazole eliminates the infection in 85-95% of cases. Unlike viral STIs like herpes or HIV that persist lifelong, trichomoniasis is caused by a parasite that antibiotics can fully eliminate. The key to successful cure is ensuring both sexual partners are treated at the same time to prevent passing the infection back and forth, completing the full course of medication even if symptoms improve quickly, and abstaining from sex for at least seven days after treatment to allow the infection to clear. If treatment fails, a longer course or higher dose of antibiotics typically cures resistant cases.
Online trichomoniasis treatments typically involve a virtual consultation with a licensed healthcare provider. During the consultation, you can discuss your symptoms including discharge characteristics, odor, itching, or discomfort, explain when symptoms started, provide your sexual history and whether your partner has symptoms, mention whether you've been tested for other STIs, and describe previous treatments if any. You'll receive a personalized treatment plan which includes prescription antibiotics and instructions to ensure your sexual partner is also treated to prevent reinfection.
Be sure to provide your doctor with detailed information, such as:
• Your symptoms including discharge color, odor, and any itching or burning
• When symptoms started and whether they're worsening
• Your sexual history and whether your partner has symptoms
• Whether you've been tested for other STIs recently
• Previous trichomoniasis infections or treatments
• Whether you're pregnant or breastfeeding
• Underlying health conditions, current medications, or any allergies
The more information you provide, the better your doctor can diagnose trichomoniasis and prescribe appropriate treatment while ensuring your partner is also treated.
LifeMD offers online trichomoniasis consultations and can provide prescriptions for metronidazole or tinidazole to treat the infection. You can have these sent to your local pharmacy, where your medication will be prepared for pick-up. Your provider will also discuss partner treatment and safe sex practices.
When it comes to treating trichomoniasis, the infection is typically cured within one week of taking antibiotics. With single-dose treatment (two grams of metronidazole or tinidazole taken at once), the parasite is eliminated quickly, though symptoms may take a few days to fully resolve. Most people notice significant symptom improvement within two to three days, with complete resolution within five to seven days. With the seven-day metronidazole course, symptoms often improve within two to three days of starting treatment.
It's important to abstain from sexual activity for at least seven days after treatment to ensure the infection is completely cleared and to avoid reinfection. Both you and your partner should be treated simultaneously and avoid sex until both have completed treatment and symptoms have resolved. If symptoms don't improve after a week or return shortly after treatment, contact your healthcare provider as this may indicate treatment failure or reinfection requiring a different treatment approach.
