For a straightforward vaginal yeast infection, yes: one 150 mg fluconazole tablet is the standard treatment. It starts on the fungus within hours; symptoms ease over 1 to 3 days, and the NHS says see your doctor if nothing has improved after 7 days.
Where one pill is not the plan: severe infections (a second dose at 72 hours is common), recurrent infections (four-plus a year gets a longer schedule), pregnancy (pills avoided; creams instead), non-vaginal fungal infections (multi-day courses), and symptoms that were never yeast - BV and some STIs mimic it, and fluconazole will not touch those. First-ever episode, recurrences, or a failed single dose all point to a proper diagnosis, not a repeat pill. Pymander is a free AI doctor, 24/7 by text, and can help you decide.

Does Diflucan work with one pill?
For a straightforward vaginal yeast infection, yes - a single 150 mg fluconazole tablet is the standard treatment, and that one-pill convenience is why it is prescribed so often. The timeline: the pill starts working on the fungus within hours, but symptoms ease gradually - most people notice real improvement within 1 to 3 days, and the NHS says to talk to your doctor if symptoms have not improved after 7 days. The exceptions where one pill is not the plan: severe or complicated infections (a second dose 72 hours later is common), recurrent yeast infections (four or more a year often gets a longer schedule), infections in pregnancy (fluconazole pills are avoided - creams are the route), non-vaginal fungal infections (oral thrush, nail, and bloodstream infections take multi-day courses), and symptoms that were never yeast to begin with - bacterial vaginosis and some STIs mimic yeast, and fluconazole will not touch them. So: if this is your first-ever episode, if symptoms keep coming back, or if one pill did nothing within a week, get a proper diagnosis rather than repeating the dose.
