Fluconazole is an oral medication that is used to treat yeast infections, commonly known as thrush, caused by the candida fungus. Fluconazole is used to treat a variety of fungal infections, including vaginal, penile and oral thrush.
Fluconazole is an antifungal medicine that works by stopping candida yeasts from building new cells. So it essentially stops the candida yeast from being able to multiply and maintain itself in such high numbers. This leads to an overall reduction in the number of yeast cells, and in most cases, complete elimination of the troublesome symptoms.
A single 150mg dose of fluconazole will usually clear up 80–95% of yeast infections. However, it may not work for everyone, so if your symptoms persist or come back soon after being treated, your doctor might need to prescribe additional treatment.

Fluconazole will usually start to work after three days and you can expect your symptoms to clear up within seven days. If this doesn't happen, you may need to see your doctor so they can assess your symptoms and rule out other conditions that may be causing them. Aspects of your lifestyle can also leave you prone to yeast infections. Simple tips such as wearing loose-fitting underwear, avoiding perfumed products on your genitals, and keeping blood sugar levels in check can all help to reduce the risk of recurrence.
Fluconazole is an oral antifungal. There are other versions of this type of medication available e.g. itraconazole.
If an oral capsule is not suitable for you, you might wish to use an intravaginal cream or pessary. These are shown to be just as effective for vulvovaginal thrush.
Canesten is a brand name of several different products used to treat thrush. Canesten manufactures a 500mg clotrimazole intravaginal pessary, and 10% clotrimazole intravaginal cream 2% clotrimazole cream. Canesten also manufactures handy “combi” packs which include both a pessary or intravaginal cream, and a topical cream to treat both external vulval infection and internal vaginal infection. Intravaginal pessaries or gels are shown to have similar results to oral fluconazole when treating the symptoms of thrush.
Fluconazole is available to buy over the counter from certain pharmacies, Canesten is the most readily available type of fluconazole to purchase.
Symptoms should start to subside within three days of taking fluconazole. If your symptoms persist after a week, you should speak with your doctor.

No, fluconazole is an antifungal treatment, it works to inhibit fungal growth.
Oral fluconazole is not a first-line treatment for athlete's foot. Athlete’s foot is caused by a different type of fungus. Mild cases of athlete's foot respond well to specific topical therapies such as terbinafine cream. More severe cases do require oral therapy, however, fluconazole is not routinely used. If you have athlete's foot, it is recommended that you use a treatment designed for athlete's foot. You should not use medications for conditions that they were not prescribed for unless you have discussed this with your doctor.
Fungal nail infections are generally treated with topical therapies. If you have got a fungal nail infection, you should use a treatment designed for this. You should not use treatments that have been prescribed for other purposes without first checking this with your doctor.
Fluconazole is not a steroid, it is an antifungal treatment.
