3. HOW TO USE CANESTEN® 100mg
If Canesten 100mg 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
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.
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.
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
Do not use tampons, intravaginal douches, spermicides or other vaginal
products while using this product.

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® 100mg Pessary is for use in the vagina only:

if one pessary is used, or three consecutive nights if two pessaries

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:
Wear cotton knickers and loose clothing.
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.
