I took diflucan once when my symptoms were really bad. It helped me for about a week and then my symptoms returned. However, my doctor was telling me that it could have been because my symptoms were so bad and he suggested I take it again. I haven’t took it again because it seems that my symptoms are finally under control. In Canada where I am from we can now buy diflucan over the counter. The doctor told me that Canestan now make a pill that you can buy from the drug store. I’m not sure if that’s the case in your area but its worth a look.
Also, if you can find it the doctor prescribed me “saccharomyces boulardii” which is a strong form of probiotics they give to their patients who had a long dose of antibiotics. the pharmacist was also helpful and let me know that that is also an over the counter remedy that can be found at the drug store. If you have no luck with that being that you are in a different country and things may be different you may be able to find it at a natural food store.
The doctor suggested taking the diflucan and saccharomyces boulardii at the same time. And also told me I may have to take diflucan more then once. However because I got so far in the diet and I feel better now for about a month I havent bothered but the saccharomyces boulardii helps for sure.
