Vaginal Thrush

The medical name for vaginal thrush is ‘vaginal candidiasis’.2 Vaginal thrush is an infection caused by the yeast Candida.2 Candida yeast is a normal resident of the mouth, digestive tract, and vagina and it usually causes no harm.2 Under certain conditions, however, Candida can overgrow and cause thrush.2

How does Candida cause thrush?

Sometimes the number of candida increases. This leads to a yeast infection.3

  • Candida and the many other germs that normally live in the vagina keep each other in balance.3
  • When our immunity is weakened, the risk of developing infections increases.4
  • Candida overgrows and the balance of the vaginal environment is disturbed.3

  • Vaginal itching and burning4
  • Vaginal redness and swelling3
  • White or yellow cheese-like discharge3
  • Vaginal soreness and irritation (including pain during sex or urinating)4

It is important to know that vaginal thrush is not a sexually transmitted disease as it is not typically spread through sexual intercourse. However, some men may develop symptoms after having sexual contact with an infected partner. These symptoms may include itching, rash or irritation of the penis.3

Most cases (approximately 90 %) of vaginal thrush are uncomplicated.4 Treatment with antifungal agents is recommended and proven effective.4 These can be either topical (applied to or in the vagina) or tablets/capsules that are taken orally.4 Recurrent (If you suffer from 4 or more repeated infections within a 1-year period) or complicated vaginal thrush may need prescribed antifungal treatment for a longer period.4 An antifungal cream called Canex V cream is available over-the-counter for at home treatment of vaginal thrush.1 This cream contains clotrimazole, an antifungal cream1

Canex V is useful for the relief of vaginal itching, burning and discharge due to vaginal yeast (fungal) infections.1
