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

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

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
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.


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.



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 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. 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

If you forget to use Canesten 100mg 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 below:
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
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
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.
