Sertaconazole (pessary) is used to treat vaginal thrush. Learn how to use the medication, its common side effects, precautions to watch out for, and more.

What is this medication for?

Sertaconazole pessaries are used to treat vaginal thrush (also known as vulvovaginal candidiasis). Vaginal thrush is caused by an overgrowth of a fungus known as Candida albicans. This infection causes symptoms such as itching, swelling and a thick, white odourless discharge. This medication will prevent the growth of the fungus and clear the infection.

How should I take or use this medication?

• Insert one pessary into your vagina as deeply as possible, in a lying position in the evening, just before bedtime.
• Usually, only a single dose is required for treatment.
• Avoid vaginal intercourse during the period of treatment, until the symptoms are fully cleared.
• You may consider using a panty liner during the treatment to absorb any discharge.
• Do not use tampons, intravaginal douches, spermicides or other products in the vagina when you are using this medication.
• The treatment is not to be carried out during menstruation, as it may be less effective.

What should I do if I forget to take or use this medication?
