treatment may not have worked properly.

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 personal hygiene.
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
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:
√ Wear cotton knickers and loose clothing.
√ Wash daily.
√ After going to the toilet, wipe yourself from the front to back as a thrush infection may be transferred
from the bowel.
√ Change your sanitary protection regularly.
Χ Try to avoid wearing tights, nylon knickers and close fitting jeans.
Χ Try to avoid washing with perfumed soaps or using vaginal deodorants.
Χ Do not wash or rub yourself hard with sponges or flannels and avoid hot baths with strong
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.
