Pregnancy and breast-feeding:
If you are pregnant, breast-feeding or trying for a baby, tell your doctor or

or midwife already, follow his/her instructions carefully.

2. Before you use Canesten Pessary
Do not use Canesten Pessary:
 If you are allergic (hypersensitive) to clotrimazole or any of the other
ingredients of Canesten Pessary (see Section 6. Further Information).
 During your period as it may be less effective.

To treat internal thrush, your doctor may recommend that you use the
pessary without the help of an applicator.

Before using Canesten Pessary, you should see your doctor if:
 You are unsure whether you have thrush or this is the first time you
have had these symptoms.
 You have had more than two infections of thrush in the last six
 You or your partner have ever had a sexually transmitted disease.
 You are aged under 16 or over 60.
 You have ever had an allergic reaction to Canesten or any other
vaginal antifungal products.

1. Remove the applicator from the packaging. Pull out the plunger A until
it stops. Remove the pessary from the foil blister pack and place firmly
into the applicator B.

3. Carefully put the applicator as deep as is comfortable into the vagina
(this is easiest when lying on your back with your knees bent up). Holding
the applicator in place, slowly press the plunger until it stops so that the
pessary is deposited into the vagina.

3. How to use Canesten Pessary
If Canesten Pessary has been prescribed for you by your doctor, follow
any instructions he/she may have given you. If you purchased this
product without a prescription, follow these directions closely:
The applicator should be used to insert the pessary as high as possible
into the vagina, preferably before going to sleep at night for convenient
and comfortable treatment.
Wash your hands before removing the foil from the blister pack and again
afterwards when you have used the applicator.

4. Remove the applicator. Dispose of the applicator in a safe place, out
of the reach of children. The applicator cannot be flushed down the toilet.
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

The symptoms of thrush should disappear within three days of treatment.
If no improvement is seen after seven days you must tell your doctor. If
the infection returns after seven days you may use one further treatment,
but if you have more than two infections within six months you should see
your doctor.

Do not put the pessary in your mouth or swallow it.
If the pessary is swallowed accidentally, tell your doctor straight away or

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 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:
 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.
 Try to avoid wearing tights, nylon knickers and close fitting jeans.
 Try to avoid washing with perfumed soaps or using vaginal
 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
