Further information


Unless directed otherwise by your doctor, the pessary should be
inserted 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.
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.




Canesten 500mg Pessary is a full course of treatment for vaginal
thrush (candidiasis). It is inserted into the vagina for treatment at
the site of infection.
The active substance in Canesten 500mg Pessary is clotrimazole.
Clotrimazole belongs to a group of medicines called azoles and is
an antifungal agent which fights the cause of infections such as
vaginal thrush.

2. To fit the pessary into the applicator, the holder of the
applicator needs to be squeezed lightly at both sides. The
pessary fits tightly into the applicator and needs to be
squeezed into the holder to about 1cm.


Do not use Canesten® 500mg Pessary:

If you are allergic (hypersensitive) to clotrimazole or any of the
other ingredients of Canesten 500mg Pessary (see Section 6.
Further Information).
During your period as it may be less effective.

Special precautions:

As with other pessaries, this product may reduce the effectiveness
of rubber contraceptives, such as condoms or diaphragms.
Consequently, you should use alternative precautions for at least
five days after using this product.
Do not use tampons, intravaginal douches, spermicides or other
vaginal products while using this product.
Avoid vaginal intercourse while you have thrush and during use of
this product because your partner could become infected.

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


Using other medicines:

Please tell your doctor or pharmacist if you are taking or have recently
taken any other medicines, including medicines obtained without a
Inform your doctor if you are taking tacrolimus or sirolimus
(used to reduce the immune response to prevent rejection after an
organ transplant).

Pregnancy and breast-feeding:

If you are pregnant, breast-feeding or trying for a baby, tell your
doctor or midwife before using Canesten 500mg Pessary. If you
have informed your doctor or midwife already, follow his/her
instructions carefully.
To treat internal thrush, your doctor may recommend that you
use the pessary without the help of an 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 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.

Canesten® 500mg Pessary is for use in the vagina only:

Do not put the pessary in your mouth or swallow it.
If the pessary is swallowed accidentally, tell your doctor straight
away or contact the Accident and Emergency Department of
your nearest hospital.

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 advice.
