Canesten Pessaries are used to treat vaginal thrush (candidiasis). Thrush is caused by an overgrowth of the fungus Candida albicans in the vagina, leading to symptoms like itching, burning, and discharge. The pessaries work by delivering the antifungal agent clotrimazole directly to the source of the infection to eliminate the fungus and provide symptom relief.

What is Canesten Pessaries?

What is Canesten Pessaries?

Canesten Pessaries are used to treat vaginal thrush (candidiasis). Thrush is caused by an overgrowth of the fungus Candida albicans in the vagina, leading to symptoms like itching, burning, and discharge. 

The pessaries are available in different strengths to suit various treatment needs. The 500mg pessary is a single-dose treatment, while the 200mg pessaries are used over three consecutive nights, and the 100mg pessaries are used for six consecutive nights. They can be used alongside external creams to provide additional relief from itching and irritation around the vulva.

How Do Canesten Pessaries Work?

Canesten Pessaries contain clotrimazole, an antifungal agent that works by disrupting the cell membranes of the fungi, thereby killing them and clearing the infection. These pessaries are inserted high into the vagina using the provided applicator, allowing the medication to target the infection directly. This treatment is typically effective within a few days, although some women may need to use the pessaries for up to seven days to see full results.

They are commonly used to treat vaginal thrush, candidiasis, yeast infections, and urinary tract infections.

Frequently asked questions

Everything you need to know about Canesten Pessaries before you start.

1. How do Canesten Pessaries work?

Canesten Pessaries contain clotrimazole, which targets the overgrowth of Candida, disrupting its cell membrane and eliminating the infection. The pessary dissolves inside the vagina, releasing the active ingredient directly at the infection site.

2. How long do Canesten Pessaries take to work?

Relief from symptoms may start within a day of using the pessary, but it may take 3-7 days for the infection to clear completely. If symptoms persist beyond 7 days, consult your doctor.

3. How should I use Canesten Pessaries?

Insert the pessary high into the vagina using the provided applicator before going to bed. The frequency depends on the dosage: a 500mg pessary is a one-night treatment, 200mg is used for 3 nights, and 100mg for 6 nights.

4. Can I use Canesten Pessaries if I’m pregnant?

During pregnancy, it is advised to consult a healthcare professional before use. While the pessaries can be used to treat thrush during pregnancy, the oral capsule should be avoided.

5. What should I do if the pessary does not dissolve properly?

If you notice undissolved pieces of the pessary, consult a doctor or pharmacist. Pessaries require moisture to dissolve, so ensure they are inserted as high into the vagina as possible.
