Trichomoniasis is a Sexually Transmitted Infection (STI) affecting both males and females.

It may result in pain, discomfort, and other issues.

However, about 70% of people with Trichomoniasis do not have any signs or symptoms.

This STI cannot be cured without medication.

Therefore, people experiencing symptoms may need to take a Trichomoniasis medication to treat them.

This article covers the different types of Trichomoniasis medication, their dosages, and potential side effects.

Medications used for Trichomoniasis

Medications such as Metronidazole and Tinidazole can treat this parasitic STI. 

These medications are antibiotics that target the parasite responsible for Trichomoniasis.

Some people may not experience symptoms, which makes them unaware of the need for treatment.

However, upon receiving a prescription, it’s imperative to complete the entire course of medication, even if symptoms alleviate before completion. 

Trichomoniasis medication usually starts working within a few days. 

Trichomoniasis is the most common curable STI globally, with an estimated 156 million new cases among people aged 15-49 in 2020.


Metronidazole is the most common medication used to treat Trichomoniasis. 

This antibiotic effectively targets the parasite, eliminating it from the body. 

The usual prescription involves a short course ensuring a swift and thorough response.

Metronidazole is available as oral medication, cream, gel, and other formulations.

Tinidazole is another antibiotic that can treat Trichomoniasis. 

It works similarly to Metronidazole but may be more effective in some cases.

Tinidazole attacks the Trichomonas vaginalis parasite, providing an effective solution for Trichomoniasis.

For those who may be allergic to or intolerant of Metronidazole, Tinidazole offers a reliable alternative.

Alternative medicines for Trichomoniasis

In some cases, Metronidazole and Tinidazole may not be as effective or cause intolerable side effects. 

In these cases, alternative medications may help. 

These include:

  • Clindamycin: This antibiotic can treat Trichomoniasis in pregnant women or those who cannot tolerate Metronidazole or Tinidazole
  • Paromomycin: This antibiotic helps treat recurring Trich when Metronidazole is ineffective
  • Secnidazole: This is a newly FDA-approved antibiotic that can be effective in treating Trichomoniasis

Dosages of Trichomoniasis medications

The dosage of Trichomoniasis medication will depend on the type of medication and the severity of the infection.

The oral form of Metronidazole is usually taken as a single dose or over several days. 

Usually, Metronidazole is taken as a single dose of 2 grams or as a 7-day course of 500 milligrams twice a day.

The topical form is administered directly to the afflicted area.

Tinidazole is usually taken as a single dose of 2 grams.

Among the alternative medicines, Clindamycin and Paromomycin are usually taken over several days.

A doctor decides the dosage of Clindamycin after seeing the severity of a case.

They may suggest a dose of 300- 450 mg, to be taken every 6 hours. 

The recommended dosage of Paromomycin treatment for Trichomoniasis is 4g of a 6.25% cream of Paromomycin once daily at bedtime for 14 days to treat Trichomoniasis.

Secnidazole is normally taken as a single dose of 2 grams.

Side effects

Headache – side effect

Like any medication, Trichomoniasis medication can cause side effects, although not everyone will experience them.

Common side effects of Metronidazole and Tinidazole include nausea, vomiting, and a bitter or metallic taste in the mouth.

Less common side effects include headache, dizziness, and heartburn. 

However, severe side effects are rare. 

Clindamycin can cause side effects such as Diarrhea, while Paromomycin can cause stomach cramps, among others. 

Secnidazole can cause headaches, nausea, and vomiting.

Some Trichomoniasis medications, such as Metronidazole and Clindamycin, are safe to take during pregnancy. 

However, others, such as Tinidazole, should be avoided.

Trichomoniasis medication can interact with other medicines, so an individual should tell the doctor about any other treatments they are taking.

Don’t skip testing for Trichomoniasis if planning a pregnancy. Pregnant women with Trichomoniasis are more likely to have their babies too early (preterm birth).

Medications can treat Trichomoniasis, a common STI. 

Metronidazole and Tinidazole are the most common medications used to treat Trichomoniasis.
