Canestan 500Mg Pessary is a treatment for thrush. Itching, swelling, redness, unusual discharge, burning, and soreness are common symptoms. Thrush doesn't usually change the pH level and has no odour. It may feel uncomfortable, but there's no need to be scared. Thrush is not an STI or a serious condition and in most cases, it can be treated easily and effectively. It is also normal and very common – 3 in 4 women suffer from it at least once during their lifetime and it's not caused by a lack of hygiene. Canesten is a suitable brand for women.
