1. WHAT IS CANESTEN® 200mg PESSARY

AND WHAT IS IT USED FOR?

Canesten 200mg Pessary is indicated for the treatment of vaginal thrush. It is inserted into the vagina for treatment at the site of infection. Only use this product if you have been previously diagnosed by your doctor as having vaginal thrush.

The active substance in Canesten 200mg 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. BEFORE YOU USE CANESTEN® 200mg PESSARY

Do not use Canesten® 200mg Pessary:

  • If you are allergic (hypersensitive) to clotrimazole or any of the other

    ingredients of Canesten 200mg Pessary (see Section 6. Further Information).

  • During your period as it may be less effective.

Before using Canesten® 200mg 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 months.
  • 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.

  • You have any of the following symptoms:

    • Irregular vaginal bleeding.
    • Abnormal vaginal bleeding or a blood-stained discharge.
    • Ulcers, blisters or sores of the vagina or vulva.
    • Lower abdominal pain.
    • Pain or difficulty in passing urine.
    • Fever or chills.
    • Feeling sick or vomiting.
    • Diarrhoea.
    • A foul smelling discharge from the vagina.

This is because Canesten 200mg Pessary may not be the right treatment for you.

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.

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 prescription.

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 breastfeeding:

Canesten 200mg Pessary can be used in pregnancy and breastfeeding. If you are pregnant, breastfeeding or trying for a baby, tell your doctor or midwife before using Canesten 200mg Pessary. If you have informed your doctor or midwife, 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® 200mg PESSARY

If Canesten 200mg 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 three consecutive nights for convenient and comfortable treatment.

    Remove the applicator. After use, take all the

    components apart for cleaning and wash thoroughly in warm (not boiling) soapy water, rinse for 30 seconds and wipe the parts carefully.

Store it in a clean and safe place.

For re-use, ensure the red lock is replaced on the plunger and repeat the process from Step 2.

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.

As the pessary dissolves in the vagina, it may be helpful to wear a panty liner. It may leave a white chalky residue after using the pessary, which 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.

  • If you have more than two infections within six months you should see

    your doctor.

Canesten® 200mg 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.

If you forget to use Canesten® 200mg Pessary:

Canesten 200mg Pessary should be used for three consecutive nights. 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 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:

3 Wear cotton knickers and loose clothing.

3 Wash daily.

3 After going to the toilet, wipe yourself from the front to back as a thrush infection may be transferred from the bowel.

3 Change your sanitary protection regularly.

7 Try to avoid wearing tights, nylon knickers and close fitting jeans. 7 Try to avoid washing with perfumed soaps or using vaginal deodorants. 7 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. For UK residents only: if you have any questions or would like more information, call our Canesten Advice Line on 0845 758 5030. Calls charged at local rate.
