Health Centres - Ecostatin pessaries (econazole)
How does it work?
Ecostatin pessaries contain the active ingredient econazole. Econazole is an antifungal medicine used to treat infections with fungi and yeasts. Ecostatin pessaries are used to treat fungal infections of the vagina, such as vaginal thrush.
Econazole kills fungi and yeasts by interfering with their cell membranes. It works by stopping the fungi from producing a substance called ergosterol, which is an essential component of fungal cell membranes. The disruption in production of ergosterol disrupts the fungal cell membrane, causing holes to appear in it.
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. As econazole causes holes to appear in the cell membranes, essential constituents of the fungal cells can leak out. This kills the fungi and treats the infection.
Econazole pessaries are inserted into the vagina to treat infections of the vagina with yeasts, in particular Candida albicans. This infection causes inflammation and discharge from the vagina and is often known as vaginal thrush. Inserting the medicine high into the vagina allows the econazole to act directly in the area of infection.
Your doctor may prescribe one single econazole pessary, or a course of three pessaries to treat the infection. The pessaries can also be used in combination with econazole cream applied directly to the outside of the vagina (vulva and labia) to help relieve the external symptoms of the infection, such as itching, inflammation and soreness. Ecostatin twin pack contains econazole pessaries together with econazole cream for the external symptoms.
What is it used for?
-
Inflammation of the vagina caused by infection with Candida albicans or other yeasts (also known as vaginal thrush).
Warning!
- Ecostatin pessaries must not be taken by mouth. They are for vaginal use only.
- The pessary should be inserted into the vagina at bedtime using the applicator provided.
- Ecostatin 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 while using this medicine, or preferably avoid having sex until after the infection has cleared up. Remember that having sex while you still have the infection is likely to transmit the infection to your partner, who could then transfer it back to you.
- If your sexual partner also has symptoms of thrush (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 econazole cream, to prevent you being re-infected. Ask your doctor or pharmacist for advice.
