Hi there and thank you for your question. I can appreciate your concern in this matter and I ll try help you where I can. Treatment for yeast infections (caused mainly by Candida albicans which is a fungus) varies in form of medication, route of administration, dosages and manners of application. The routes involved include either being taken orally or inserted vaginally and the dose regimens can be daily or in the evening. The medication can be found in a pill, pessary or ointment form and the duration of treatment can last 1, 3, 7 or even 10 days. Therefore, there can be quite a bit of failed treatment protocols as well as a lot of confusion that can occur. The medication that I have previously prescribed for my patients that works very well is a single dose of fenticonazole 600mg pessary that is inserted in the vagina and the infection usually clears up after the third day. You can speak to your pharmacist about supplying this specific medication for you and see how you respond. If this also fails then I would suggest seeing your doctor to exclude other issues such as a secondary or superimposed infection with this current one. I hope this helps though and good luck.
