About DIFLUCAN ONE® Yeast Infection Treatment

The #1 doctor-prescribed treatment for vaginal yeast infections, available without a prescription.

When you have a yeast infection, it helps to know that there is an effective treatment in a convenient single dose. DIFLUCAN ONE is a treatment that's clinically proven to relieve the itching, burning and discharge associated with vaginal yeast infections (VYIs). So whether this is the first time you've had a VYI, or it's the first time you're trying DIFLUCAN ONE, the information below will tell you what you need to know about the #1 brand prescribed by doctors in Canada for the treatment of yeast infections.

What is DIFLUCAN ONE?

DIFLUCAN ONE is a 1-pill, 1-dose, 1-day treatment that is clinically proven to cure most yeast infections. It can be taken anytime, anywhere, and it starts to relieve your symptoms in just one day.

Did you know?

For years, DIFLUCAN has only been available by prescription – and it has become the #1 brand prescribed by doctors for the treatment of yeast infections. But it’s also available without a prescription as DIFLUCAN ONE.

How does DIFLUCAN ONE work?

DIFLUCAN ONE works by stopping the growth of the fungi that caused the yeast infection in the first place. Although you only need to take one pill, the medication in DIFLUCAN ONE, fluconazole 150 mg, continues working in your body for several days until your yeast infection is cured. You'll notice your symptoms begin to disappear within 24 hours and within 7 days they should be gone completely. If your symptoms have not improved within 3 days and have not completely disappeared within 7 days, contact your doctor.
