The Canesten Thrush Pessary is a single-dose vaginal thrush treatment containing clotrimazole 500 mg. Inserted at bedtime with the applicator provided, it works at the site of the infection to clear the cause of thrush. It is a pharmacy (P) medicine — no prescription needed, just a short suitability check.
What is the Canesten pessary?
A pessary is a small, solid vaginal tablet. This one delivers a full course of thrush treatment — 500 mg of the antifungal clotrimazole — in a single dose, killing the Candida yeast that causes vaginal thrush at the source of the infection.
How to use the Canesten Thrush Pessary
- Use the applicator to insert one pessary as high as possible into the vagina.
- Insert it at bedtime — lying down overnight helps it stay in place and dissolve properly.
- It is a single-dose treatment; symptoms should start to improve within 3 days.
- If symptoms have not improved within 7 days, see your doctor.
- Not for use under 16 or over 60 without medical advice.
What to expect
As the pessary dissolves you may notice some chalky residue or discharge over the next day or two — this is normal and does not mean the treatment has failed. The external itching and burning usually begin to settle within a day or two. If external symptoms bother you, pair the pessary with Canesten 2% external cream.
Side effects and cautions
Some women notice mild, short-lived burning, itching or irritation after insertion. See a doctor before use if this is your first episode of thrush, you have had more than two infections in the past six months, you are pregnant or breastfeeding, or you have abnormal bleeding, ulcers or lower tummy pain. The pessary can damage latex condoms and diaphragms — use alternative precautions during treatment and for up to 5 days afterwards.
