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

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.

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.

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 100mg 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.
3. How to use Canesten 100 mg Pessary
If Canesten 100 mg 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 on six consecutive nights for
convenient and comfortable treatment. Alternatively, two pessaries may be
inserted into the vagina before going to sleep on three consecutive nights.
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.

4. Remove the applicator. After use, remove plunger A completely by
pulling it out of the applicator B. Then wash it in warm (not boiling) soapy
water, rinse and dry carefully.
5. After completing the treatment, 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.
Canesten 100 mg 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

If you forget to use Canesten 100 mg Pessary:
Canesten 100mg Pessary should be used for six consecutive nights if
one pessary is used, or three consecutive nights if two pessaries are
used. However, if you forget to insert a pessary, follow the advice given
When you remember, continue with your course of treatment. If you have
forgotten for more than one day, your infection may not be fully treated,
so if symptoms persist upon completion of this course, see your doctor.

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.

treatment of thrush, do not hesitate to ask your doctor or pharmacist for
