A Canesten pessary contains clotrimazole, a treatment for thrush, which is a yeast infection that can occur inside the vagina. The pessary is inserted into the vagina in order to soothe the symptoms and treat the thrush infection. The pessary tablet is placed into an applicator shaped like a long plastic stick. This is then inserted into the vagina, pushing up to release the tablet the same way you would with a tampon applicator.
Thrush is caused by the Candida fungus. This is produced naturally in the vagina but it causes symptomatic thrush to occur when the numbers of the fungus increase, or if your immune system is lower than usual, producing less good bacteria to keep it under control. The clotrimazole contained in Canesten kills the fungus to clear up the infection.
The Canesten pessary is a one-off treatment that usually begins to work overnight. You can expect your symptoms to be gone after a week. In addition to the pessary, you may also need to use a Canesten cream to treat any external itching and irritation.
Clotrimazole is the active ingredient within the Canesten pessary.
The inactive ingredients in the Canesten pessary are lactose monohydrate, microcrystalline cellulose, lactic acid, maize starch, crospovidone, calcium lactate pentahydrate, magnesium stearate, colloidal anhydrous silica and hypromellose.
Canesten pessaries are safe to use and do not commonly cause severe allergic reactions in users. If you are allergic to clotrimazole or any of the inactive ingredients in this pessary make sure to let your prescribing doctor know. You should look out for signs and symptoms of a severe allergic reaction including a rash, dizziness, facial swelling and itchiness, and difficulty breathing. If you experience any of these symptoms, get medical help as soon as possible.
Take your time to read through the instructions carefully before use. Wash your hands before you begin and carefully take the pessary out of the packet. Place the tablet in the holder, which is the wider end of the plastic applicator. When you’re ready, get into a comfortable position where you can easily slide the applicator into your vagina. Place it inside just like you would with a tampon, getting it as high up into the vagina as you can. Slide the plastic end upwards in a similar way to using a tampon applicator to release the tablet and then gently remove the empty applicator. It’s recommended to use the pessary at nighttime to allow it to work overnight. You may get a white, chalk-like discharge from the tablet but this is completely normal.
The Canesten pessary contains a 500mg dose of clotrimazole which is for single use only.
The Canesten pessary is for one use only. If you are also using Canesten cream for external symptoms, the cream can be used until your symptoms have disappeared.

Your fertility will not be affected by Canesten.
Vaginal thrush can be treated with either a vaginal pessary, intravaginal cream, or with an oral fluconazole tablet. Thrush typically also infects the external vulval area, causing itching and discomfort. To treat the external infection, an antifungal cream is recommended alongside the Canesten pessary.
Canesten pessary is for the treatment of vaginal thrush only.
Canesten is an anti-fungal medicine, it’s not an antibiotic. Antibiotics are designed to fight bacterial infection, not fungal infections such as thrush.
