Brief Answer:
Amphotericin drug of choice

Detailed Answer:
Hi,

Thanks for choosing health care magic for your query.

I understand your concern about effective treatment for your daughter's disease.

Candida is a yeast like fungi and most cases of systemic candidiasis follow an endogenous infection by this commensal.

You are right that nystatin is more effective against candidial infections of the skin rather than systemic candidiasis.

Intravenous Amphotericin B, alone or in combination with Flucytosine, is recommended for systemic candidiasis.

Fluconazole can also be used effectively.

Antifungal suspceptibility testing can be done to determine the most effective antifungal in your daughter's case.

I hope I have cleared your doubts.

Please let me know, if I can assist you further.

Thanks.
