Overview

Vaginal thrush is caused by an overgrowth of the yeast Candida albicans, which leads to itching, soreness, discharge, and swelling. While oral capsules work throughout the body, Canesten 500mg Pessary provides direct relief inside the vagina, targeting the infection head-on.

What is Canesten Pessary

The pessary contains clotrimazole 500mg, a highly effective antifungal medicine that stops yeast from multiplying. It is inserted at bedtime and works overnight, making it a discreet and convenient option for women who prefer not to take tablets.

Directions

  • Insert one 500mg pessary deep into the vagina at bedtime using the applicator provided.
  • Wash hands before and after use.
  • Do not use tampons during treatment.
  • Symptoms usually improve in 2-3 days, with full relief in up to 7 days.

Side Effects

Most women tolerate Canesten Pessary well, but side effects may occur.

Common (may affect up to 1 in 10 people):

  • Mild burning, stinging, or irritation after insertion
  • Vaginal discomfort


Less common (may affect up to 1 in 100 people):

  • Itching or redness around the vulva
  • Skin rash


Rare but serious (seek urgent medical advice):

  • Severe allergic reaction (swelling, rash, difficulty breathing)


Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet that comes with your medicine for full details. If you notice anything unusual or concerning, stop using the treatment and seek medical advice promptly. In an emergency, call 999 or go to A&E.

Warnings

  • Not suitable if allergic to clotrimazole or other antifungals.
  • Avoid use during pregnancy unless advised by a prescriber (insert without applicator if used).
  • Creams or pessaries may weaken latex condoms and diaphragms — use alternative contraception during treatment.
  • Do not use during your period, as it may reduce effectiveness.
Frequently asked questions
  • What is the Canesten pessary and how does it work?

    The Canesten pessary contains clotrimazole, an antifungal medicine used to treat internal vaginal thrush. It works by reducing the growth of Candida yeast inside the vagina. The treatment is inserted at night so it can dissolve and deliver medication directly to the source of infection.

  • How do I insert the Canesten pessary correctly?

    The pessary should be placed high into the vagina using the applicator provided, ideally at bedtime. Lying down helps the medicine stay in place as it dissolves. Wash hands before and after use and avoid sexual activity during treatment to prevent discomfort or reduced effectiveness.

  • How long does the Canesten pessary take to work?

    Many women feel relief within a day, but full improvement can take up to three days while the infection clears. If symptoms have not improved after seven days, reassessment is recommended. Persistent symptoms may require an alternative antifungal such as fluconazole.

  • Should I use a cream alongside the Canesten pessary?

    Yes, if you have external itching or soreness, using a clotrimazole cream alongside the pessary provides more complete relief. The pessary targets the internal infection, while the cream helps soothe external skin irritation.

  • Who should avoid using the Canesten pessary?

    The pessary should not be used if you are allergic to clotrimazole, have unusual vaginal bleeding, pelvic pain, fever, or if this is your first episode of vaginal symptoms. Pregnant women require clinician advice before using internal thrush treatments.

  • What side effects can occur with Canesten pessary?

    Some women may experience mild burning, stinging, swelling or increased discharge as the pessary dissolves. These reactions are usually temporary. Severe irritation, worsening symptoms or any signs of allergy warrant stopping treatment and seeking medical advice.

  • Does the Canesten pessary treat recurrent thrush?

    The pessary can help clear individual episodes, but women with repeated infections might need longer courses or oral treatments. Recurrent thrush should be reviewed to rule out triggers such as antibiotics, diabetes or misdiagnosis of another condition.

  • Can I use the Canesten pessary if I’m taking antibiotics?

    Yes, but antibiotics can make thrush more likely and may delay recovery. If symptoms become more severe while on antibiotics, pairing the pessary with an external cream may help. Recurrence after antibiotics is common and may require follow-up treatment.

  • Can I use the pessary with hormonal contraception?

    Most hormonal contraceptive methods are unaffected by the Canesten pessary. However, clotrimazole can weaken latex condoms for several days, so use non-latex condoms if needed during this period.

  • Should I avoid washing or using soaps after inserting the pessary?

    Avoid fragranced soaps, vaginal washes or douching, as these can irritate the area and worsen symptoms. Gentle washing with warm water only is usually best during treatment. Harsh products can disrupt the natural balance of the vagina.

  • Can the Canesten pessary affect fertility or trying to conceive?

    The pessary does not affect fertility, but sexual intercourse should be avoided during treatment. If you are trying to conceive, treat thrush promptly and avoid using the pessary immediately before intercourse due to leakage and reduced comfort.

  • Can I use tampons after using the Canesten pessary?

    No. Tampons can absorb the medication and make treatment less effective. Wait until treatment is complete and symptoms have settled before using tampons again. Pads or panty liners are preferred during treatment.

  • What if the pessary comes out or dissolves too quickly?

    If the pessary falls out before dissolving or you notice unusually rapid leakage, insert a new dose. This may happen if inserted too shallowly. Using the applicator and lying down afterwards usually prevents this.

  • Can I use the pessary for external symptoms only?

    No. The pessary only treats internal yeast infection. If you have mainly external itching, a clotrimazole cream is more suitable. Many women use both for complete relief of both internal and external symptoms.

  • Why does the pessary cause increased discharge?

    Increased discharge is usually just the medication dissolving and exiting the vagina. This is expected and does not mean the treatment has failed. Wearing a pad overnight helps manage this comfortably. If discharge becomes foul-smelling or coloured, another condition may be present.
