About This Medication

What the Medication is Used For

DIFLUCAN 150 is indicated for the treatment of vaginal yeast (fungal) infections. It can be taken anytime, anywhere to relieve itching, burning and discharge associated with vaginal yeast infections. DIFLUCAN 150 is a clinically proven, effective single-dose cure for most vaginal yeast infections that starts to work in 1 day.

What is a Yeast Infection

A "yeast infection" may occur any time there is an overgrowth of yeast organisms in the vagina. The vagina normally has bacteria and yeast organisms present. Under some conditions, the number of yeast organisms rises, irritating the tissues of the vagina and vaginal opening.

Conditions that make this more likely to occur:

  • illness
  • use of antibiotics
  • changes in hormone levels
  • pregnancy
  • use of oral contraceptive pills
  • just before a woman's period
  • diabetes
  • hot humid weather
  • continuous use of panty liners
  • tight, non-breathing clothing
  • nylon underwear, pantyhose, wet bathing suits or damp workout wear
  • perfumed soaps, bubble baths or douching may cause vaginal irritation and upset the normal balance

Refrain from vaginal intercourse when you have a yeast infection to avoid infecting your partner and to minimize additional discomfort. If your partner has any genital itching, redness or discomfort, they should talk to their doctor and mention that you are treating a yeast infection.

When a "yeast infection" occurs, the body responds with:

  • an increase in vaginal secretions.
  • secretions are generally thick and sticky (cheesy or curd-like, similar to cottage cheese), but odourless.
  • secretions that are irritating to the tissues of the vaginal area
  • itching, redness, and swelling of the vaginal area
  • red spots or sores may develop, especially if the area has been scratched
  • soreness in the vagina
  • pain during sexual relations is common.

DIFLUCAN 150 is an antifungal medication. The active ingredient fluconazole works by stopping the growth of the fungi that cause vaginal yeast infections.

Proper Use of This Medication

Consult your doctor if this is your first yeast infection, or if you have a second yeast infection in less than 2 months after treating a prior infection.

Usual Dose

Adults (≥ 12 years old): Take DIFLUCAN 150 by mouth as a one-time only dose, with or without food, or as directed by your doctor. DO NOT take more than one dose for this infection. If your symptoms have not improved within 3 days and disappeared in 7 days, contact your doctor.

Clearing a yeast infection does take time. Although DIFLUCAN 150 is taken only once, DIFLUCAN 150 therapy does not cure the infection in just one day, the medication remains active in your body for several days. Most patients can expect to see symptom relief begin within 24 hours after taking the capsule. As DIFLUCAN 150 works to cure the infection, symptoms will lessen and eventually disappear.


In case of accidental overdose call a doctor or poison control centre immediately, even if there are no symptoms.
