Canesten 200mg pessaries contain the active ingredient clotrimazole, which is an antifungal medicine used to treat infections with fungi and yeasts, such as Candida Fungi (thrush infection).

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 pessaries are inserted into the vagina to allow the clotrimazole to act directly in the area of infection.

Ingredients

Each pessary contains Clotrimazole 200mg

Usage and Instructions

Adults and children over 16 years of age:

One pessary should be inserted daily (preferably at night) for three consecutive days. A second treatment may be carried out if necessary.

There is no separate dosage schedule for the elderly.

Canesten pessaries need moisture in the vagina in order to dissolve completely, otherwise undissolved pieces of the pessary might crumble out of the vagina. Pieces of undissolved pessary may be noticed by women who experience vaginal dryness. To help prevent this it is important that the pessary is inserted as high as possible in to the vagina at bedtime.

Generally:

treatment during the menstrual period should not be performed due to the risk of the pessary being washed out by the menstrual flow. The treatment should be finished before the onset of menstruation.

Do not use tampons, intravaginal douches, spermicides or other vaginal products while using this product.

Vaginal intercourse should be avoided in case of vaginal infection and while using this product because the partner could become infected.

Children:

Not for use in children under 16.
