From the Research

Astro cream should be inserted vaginally to be effective, as external application around the vaginal area would not deliver the medication where it needs to work and would significantly reduce its effectiveness. The most recent and highest quality study, 1, published in 2024, demonstrates the importance of proper application of antifungal treatments for severe vulvovaginal candidiasis, with three-dose regimens showing higher mycological cure rates compared to two-dose regimens. Key points to consider when applying Astro cream include:

  • Using the applicator specifically designed for proper vaginal insertion to ensure the medication reaches the intended treatment area
  • Following the package instructions or consulting with a healthcare provider for specific guidance on the proper application method
  • Understanding that the vaginal canal has a unique environment and absorption properties that many vaginal medications are formulated to work with
  • Recognizing that improper application could result in treatment failure and persistence of symptoms, as noted in studies such as 2 and 3, which compared the efficacy of different antifungal treatments for vulvovaginal candidiasis. It is essential to prioritize the proper application of Astro cream to ensure its effectiveness in treating the intended condition, as supported by the latest evidence from 1.
