How long until my thrush drugs work?
Thrush infection duration:
With the right treatment, a thrush infection should not last longer than 10-14 days.
​
If it goes on longer than this, it is a medical emergency as you could develop nerve damage and vestibulodynia.
​
Most Doctors are not taught this and do not understand the stakes – you need to see a vulva dermatologist.
​
It's advisable to have boric acid pessaries on hand to use if the clotrimazole fails and the infection does not clear in 10 days. Some doctors might suggest a 500mg medical grade boric acid pessary once a night for 14 nights until you can see a vulva consultant. Note for some women boric acid pessaries irritate their skin, if your symptoms worsen after boric acid use - discontinue and wait to see a vulva derm (do not wait long!) You can try phoning 111 and ask for a gynaecologist to prescribe you a long course oral itraconazole (a second line azole drug) until you see a clinician in person.
