Journey Overview

#1 Book an Appointment
If you tested with us, you can usually book directly for treatment.
If you tested elsewhere, a consultation will first be required so that one of our clinicians can review your symptoms, medical history, and test results. Bringing evidence of your positive result is recommended where possible.
#2 Receive Treatment
If treatment is clinically appropriate and safe to proceed, you will be asked to attend the clinic for treatment.
#3 Further Actions
• Avoid sexual contact until you and your partner(s) have completed treatment and symptoms have resolved.
• Inform recent sexual partner(s) so they can receive appropriate treatment.
• If taking metronidazole, avoid alcohol during treatment and for 48 hours after your final dose.
• Routine repeat testing is not required if symptoms resolve. If symptoms persist or return, speak to your healthcare professional; NAAT/PCR testing should be performed at least 3 weeks after treatment.

FAQs
We offer consultation, diagnosis and treatment for Trichomonas Vaginalis. If you have already tested positive elsewhere, a consultation is required before treatment is prescribed. Trichomoniasis is usually treated with metronidazole, with the dose and regimen based on your individual circumstances. Current sexual partner(s) should receive appropriate treatment to reduce the risk of reinfection.
Yes. Current sexual partners and any recent partners should be informed so they can be tested and treated, even if they do not have symptoms.
If partners are not treated, you can become infected again after treatment. Avoid vaginal, anal, and oral sex until everyone has completed treatment and symptoms have resolved.
Trichomoniasis treatment is highly effective when taken as prescribed. Metronidazole cures most infections.
Complete the full course, avoid alcohol while taking metronidazole, and avoid sex until both you and your partner(s) have completed treatment to reduce the risk of reinfection. If symptoms continue after treatment, further assessment may be needed.
Metronidazole is generally well tolerated, but common side effects include nausea, a metallic taste, loss of appetite, headache, abdominal discomfort, and dizziness.
Avoid alcohol during treatment and for 48 hours after your last dose, as it can cause severe nausea and vomiting. Seek medical advice if you develop signs of an allergic reaction or cannot complete your treatment because of side effects.
Metronidazole is generally considered safe during pregnancy and is recommended to treat trichomoniasis. The most appropriate treatment regimen will depend on your individual circumstances.
Treating the infection is important because untreated trichomoniasis has been linked to pregnancy complications, including preterm birth. Your sexual partner(s) should also be treated to prevent reinfection.
No. There are no home remedies or over-the-counter treatments that cure Trichomonas Vaginalis.
The infection requires prescription antibiotics, usually metronidazole. Sexual partner(s) should also be treated, and you should avoid sex until treatment is complete.
Symptoms may begin to improve within a few days of starting treatment. Complete your prescribed treatment and avoid sexual contact until you and your partner(s) have completed treatment and symptoms have resolved.
Menopause does not usually reduce the effectiveness of antibiotics used to treat trichomoniasis.
However, vaginal dryness and thinning caused by lower oestrogen levels can cause symptoms that persist after the infection has cleared. If symptoms continue, further assessment can determine whether they are due to menopause or another condition.
If your symptoms continue or return after treatment, you should be reassessed. This may be due to reinfection, treatment failure, or another condition causing similar symptoms.
If repeat PCR testing is required, it is generally recommended to wait at least 3 weeks after completing treatment to reduce the chance of detecting non-viable organisms.
Yes, although treatment failure is uncommon. Persistent infection may result from reinfection, not completing treatment, or, less commonly, antimicrobial resistance.
If symptoms persist, further assessment may include repeat testing and an alternative treatment regimen, such as a longer course of metronidazole or tinidazole, where appropriate.
A routine test of cure is not usually required if your symptoms have resolved and there is no concern about reinfection. If symptoms persist or return, or reinfection is suspected, you should be reassessed. If repeat NAAT/PCR testing is needed, it should be performed at least 3 weeks after treatment.
Yes. Current sexual partner(s) should receive appropriate epidemiological treatment, even if they have no symptoms. Avoid sexual contact until you and your partner(s) have completed treatment and symptoms have resolved.
