Canesten 500mg Pessary is recommended for the treatment of candidal vaginitis.
What is Canesten 500mg pessary used for?
- Vaginal thrush (Candidal vaginitis).
- This single dose treatment should clear up the infection inside the vagina. However, you may also want to use a cream on the outside of the vagina (vulva and labia) to help relieve the external symptoms of the infection, such as itching, inflammation and soreness. Clotrimazole 1% or 2% creams are suitable for this.
How does Canesten 500mg pessary work?
- Canesten 500mg pessary contains the active ingredient clotrimazole, which is an antifungal medicine used to treat infections with fungi and yeasts.
- Clotrimazole kills the Candida fungi causing the thrush infection by interfering with their cell membranes. The cell membranes of fungi are vital for their survival. They keep unwanted substances from entering the cells and stop the contents of the cells from leaking out. Clotrimazole makes holes appear in these membranes, which kills the fungi and clears up the infection.
- The pessary is inserted into the vagina to allow the clotrimazole to act directly in the area of infection.
How do I use Canesten 500mg pessary?
- The pessary should be inserted high into the vagina as a single dose at bedtime. Use the applicator provided. Follow the instructions provided in the pack. If you have your period you should wait until it's finished before using the pessary.
- You should consult your doctor if your symptoms have not got better within a week of using the pessary.
What should I know before using Canesten 500mg pessary?
- Canesten pessaries may damage latex (rubber) condoms and diaphragms (caps) and so make them ineffective at preventing pregnancy and STIs. You should use an alternative method of contraception for at least five days after using this medicine, or preferably avoid having sex until after the infection has cleared up. Remember that having sex while you still have thrush is likely to transmit the infection to your partner, who could then give it back to you.
- If your sexual partner also has symptoms of thrush (in men these are soreness and redness of the penis, tightness of the foreskin or a white, odourless discharge from the penis), it is important that they are treated at the same time as you, for example with clotrimazole cream, to prevent you being re-infected. Ask your doctor or pharmacist for advice.
Who shouldn't use Canesten 500mg pessary?
- People who are allergic to any ingredient of the medicine.

Can I use Canesten 500mg pessary while pregnant or breastfeeding?
- The safety of clotrimazole when used during pregnancy has not been specifically studied. However, it has been used by a large number of women during pregnancy without any apparent harmful effects. As with all medicines, you should consult your doctor or midwife before using this medicine during pregnancy. If your doctor says you can use this medicine while you are pregnant you should use your fingers, not the applicator, to insert the pessary.
- Since very little clotrimazole is absorbed into the bloodstream from the vagina it is unlikely that any of the medicine will pass into breast milk. However, as with all medicines, you should get medical advice from your doctor or pharmacist before using this medicine if you are breastfeeding.
