Canesten Thrush Duo is a complete and convenient treatment for vaginal or penile thrush.

Only use this product if you have been previously diagnosed by your doctor as having thrush.

The active substances in the capsule and cream are fluconazole and clotrimazole, respectively. Fluconazole and clotrimazole belong to a group of medicines called azoles and are antifungal agents which fight the cause of infections such as thrush.

Do not use Canesten® Thrush Duo®:
  • If you are allergic (hypersensitive) to fluconazole, clotrimazole, to other medicines you have taken to treat fungal infections or to any of the other ingredients, including lactose monohydrate, cetostearyl alcohol or benzyl alcohol, of Canesten Thrush Duo (see Section 6. Further Information).
  • If you are taking astemizole or terfenadine (antihistamine medicines for allergies), cisapride (used for stomach upsets), pimozide (used for treating mental problems), quinidine (used for treating heart arrhythmia), erythromycin (an antibiotic for treating infections).


If you have any of the following symptoms do not use Canesten Thrush Duo and see your doctor as soon as possible:

  • Irregular vaginal bleeding.

  • Lower abdominal pain.
  • Pain or difficulty in passing urine.

  • You have sores, ulcers or blisters on your penis.
  • You have an abnormal discharge from your penis.

  • You have had any disease or illness affecting the liver or kidneys, or have had any unexplained jaundice.
  • You have heart problems, including heart rhythm problems.

If Canesten Thrush Duo has been prescribed for you by your doctor, follow any instructions he/she may have given you.

If the infection returns after seven days another capsule may be taken, but if you have more than two infections within six months you should see your doctor.

Some women suffer from recurrent attacks of thrush. To reduce the frequency of these attacks, the sexual partner’s penis can be treated with this cream to prevent re-infection, even if they have no symptoms of thrush.

Further information about 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.

In men, Candida can also cause thrush - a condition called balanitis (inflammation of the end of the penis). It causes any of the following symptoms: soreness and redness of the penis, tightness of the foreskin and a white, odourless discharge from the penis.

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 deodorants.
  • 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.
