What should clients do during treatment with vaginal antifungal drugs?

During treatment with vaginal antifungal drugs, clients should abstain from sexual intercourse until the treatment is complete. This recommendation is based on several factors. First, engaging in sexual activity while using antifungal medications can cause irritation to the already affected vaginal area, potentially worsening the symptoms of the yeast infection. Second, there is a risk of transmitting the infection, especially if either partner is experiencing symptoms or if the infection is not fully resolved. By abstaining, clients allow the medication to work effectively without the interruption that sexual activity may bring, ensuring a more successful treatment outcome and reducing the chance of recurring infections.

The other choices suggest practices that might compromise the treatment efficacy or the well-being of the client. For instance, continuing sexual activity with caution could still lead to irritation or discomfort, while using condoms does not completely mitigate the risks of irritation or transmission. Only abstaining if symptoms worsen does not align with the principle of completing treatment to ensure full healing before resuming sexual activity.
