4. Remove the applicator. Dispose of the applicator in a safe

Since the pessary dissolves in the vagina, it may be helpful to
wear a panty liner because it is quite common to notice a white
chalky residue after using the pessary. This does not mean that
the treatment has not worked. However, if you notice pieces of
undissolved pessary, speak to your doctor or a pharmacist, as the
treatment may not have worked properly.
The symptoms of thrush should disappear within three days of
treatment. If no improvement is seen after seven days you must
tell your doctor.

Do not put the pessary in your mouth or swallow it.

Further information about vaginal thrush:
Vaginal thrush (candidiasis) is a common infection that most women
suffer from at some time in their lives and is not caused by lack of
Thrush is caused by a yeast (fungus) called Candida which lives
harmlessly in the vagina and other parts of the body, without you
even noticing it. However, the natural balance that keeps Candida
under control can be upset by many factors such as hormonal changes
(menstruation, contraceptive pill, pregnancy, menopause), poor
health, antibiotics, perfumed soaps, bath additives and tight clothing.
If the natural pH balance is altered, the level of yeast increases and
can develop into a thrush infection causing any of the following
symptoms: persistent burning and/or itching around the vagina and
vulva, redness, swelling and soreness of the tissues of the vagina
and vulva and a whitish, odourless discharge from the vagina. Not
everybody who has thrush has all these symptoms; you may have only
one of them.
How to avoid future recurrences:
3 Wear cotton knickers and loose clothing.
3 Wash daily.
3 After going to the toilet, wipe yourself from the front to back as a
thrush infection may be transferred from the bowel.
3 Change your sanitary protection regularly.
7 Try to avoid wearing tights, nylon knickers and close fitting jeans.
7 Try to avoid washing with perfumed soaps or using vaginal
7 Do not wash or rub yourself hard with sponges or flannels and
avoid hot baths with strong perfumed oils.
If you are still worried or have any questions about the symptoms
or the treatment of thrush, do not hesitate to ask your doctor or
pharmacist for advice.
