Patient Medication Information: uses, side effects, how to take - M-Fluconazole-150

What is M-FLUCONAZOLE-150 used for?

M-FLUCONAZOLE-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. M-FLUCONAZOLE-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.

How does M-FLUCONAZOLE-150 work?

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

How to take M-FLUCONAZOLE-150:

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 M-FLUCONAZOLE-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 M-FLUCONAZOLE-150 is taken only once, M-FLUCONAZOLE-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 M-FLUCONAZOLE-150 works to cure the infection, symptoms will lessen and eventually disappear.

Overdose:

If you think you, or a person you are caring for, have taken too much M-FLUCONAZOLE-150, contact a healthcare professional, hospital emergency department, or regional poison control centre immediately, even if there are no symptoms.
