In the case of a diagnosis of Trichomoniasis, which medication can be prescribed?

The use of Metronidazole 2 grams by mouth in a single dose is the recommended treatment for Trichomoniasis because it is an effective antimicrobial agent specifically targeting the Trichomonas vaginalis parasite. This medication works by disrupting the DNA synthesis of the protozoan, thereby reducing or eliminating the infection.

In practice, the single-dose regimen is often preferred for convenience and ensuring adherence, as it typically leads to high cure rates. While other medications may have their own uses in different contexts—like Clindamycin for bacterial vaginosis or Fluconazole for Candida infections—they do not specifically address the Trichomonas infection. Benzyl peroxide cream is typically used for acne and has no efficacy against Trichomoniasis. Therefore, the correct choice of Metronidazole directly targets the causative agent of the illness, making it the appropriate treatment option.
