Trichomoniasis is caused by the activity of a small parasitic organism called Trichomonas Vaginalis (TV), and is characterised by a number of symptoms. In women, these might be symptoms commonly associated with vaginitis, such as discharge, pain, inflammation or irritation; whereas men may experience pain or slight discharge during urination. The parasite is spread via unprotected sex in most cases, but it can be transferred through the use of shared sex toys as well.

The condition is not as widespread as other STIs, and is only thought to affect around 6,000 people every year in the UK. However, it is still important if you think you might have the condition to seek treatment, as it can increase your susceptibility to other STIs, such as HIV.

This illness is treated in a similar way to most bacterial infections; with antibiotic medicine. This is usually issued in the form of Metronidazole, which is a form of nitromidazole antibiotic. It is often prescribed as a two-dose-a-day treatment for around 5—7 days.

Metronidazole kills the parasite by hindering its capacity to repair itself. In order to maintain its DNA structure, TV requires the function of nucleic acid. The drug restrains the production of this acid, and compromises the DNA structure of the parasite. This disables the progress of the organism, which then ceases to function and dies.

You cannot get this medication from our online clinic. If you think you need treatment for TV, consult with your doctor or sexual health clinic.

Types of Treatment

Types of Treatment

Trichomonas Vaginalis does not tend to go away on its own, making treatment necessary. This is usually issued in the form of antibiotic medicine, Metronidazole. This is available as a standard tablet.

How do they work?

Most antibiotics tend to work in a similar way; by disabling an infections ability to sustain itself. Bacteria and parasites will usually produce chemicals which allow them to function, and maintain cell integrity.

In the case of Trichomonas Vaginalis, the active ingredient in Metronidazole restricts the activity of nucleic acid, which prevents the parasite from maintaining its DNA structure. The offending parasite is then unable to repair itself and continue functioning, and subsequently dies.

What are the side effects?

Among the most common side effects associated with Metronidazole are headaches, dizziness and facial flushing. Please consult the leaflet provided with the product for more information.

Can I take them with other medications?

It depends on what other medications you're using. Metronidazole may affect the functionality of some medicines including lithium, or anti-coagulants. See the leaflet for more information, and always inform your prescriber of any other treatments you are currently taking.
