Canesten in Pregnancy: Is It Safe?
Canesten in pregnancy
When you are pregnant, it is natural to have questions about what is safe - and that includes everyday remedies for common complaints. This guide explains the current UK guidance on using Canesten for thrush in plain language, so you can make informed decisions for you and your baby.
Why thrush is more common in pregnancy
Vaginal thrush is a yeast infection caused by an overgrowth of candida, and it is significantly more common in pregnancy. Hormonal changes increase the amount of glycogen (sugar) in vaginal secretions, which yeast thrives on, and rising oestrogen alters the vagina's natural pH balance. Typical symptoms include itching, soreness, redness, and a thick white discharge that can look a bit like cottage cheese, sometimes with an odourless or mild yeasty smell. It is not harmful to your baby, but it can be genuinely uncomfortable, so treating it promptly is worthwhile.
Is Canesten safe in pregnancy?
Canesten's active ingredient, clotrimazole, is one of the most widely used antifungal treatments for thrush, and the vaginal cream and pessary forms are generally considered suitable for use in pregnancy. That said, you should always check with your pharmacist, GP or midwife before starting treatment, since they can confirm the right product and dose for your stage of pregnancy. The oral capsule form of thrush treatment (fluconazole) is a different matter - it is not recommended in pregnancy and should be avoided; always choose the topical cream or pessary instead.
How to use it safely and effectively
- Ask your pharmacist whether to insert the pessary or cream using your fingers rather than the supplied applicator, which is sometimes advised in later pregnancy for comfort and safety.
- Complete the full course even if your symptoms improve after a couple of days, to reduce the chance of the infection returning.
- Use the external cream alongside the internal treatment if the itching and soreness extend to the skin around the vagina.
- Avoid inserting tampons, having penetrative sex, or using spermicidal products until treatment is finished and symptoms have settled.
Preventing thrush from coming back
Wear loose cotton underwear and avoid tight synthetic trousers or tights where possible. Wash the area with plain water or a gentle emollient rather than perfumed soaps, shower gels or douches, all of which can disturb the natural balance further. Always wipe front to back after using the toilet. If you have gestational diabetes, keeping your blood sugar well controlled can also help reduce how often thrush recurs.
Frequently Asked Questions
Can I use Canesten in every trimester of pregnancy?
Topical clotrimazole cream and pessaries are generally considered appropriate throughout pregnancy, but your pharmacist or midwife may advise on insertion technique differently depending on your stage, particularly in the third trimester. Always confirm with them before use.
Why does thrush keep coming back during pregnancy?
Pregnancy hormones create ongoing conditions that favour yeast overgrowth, so recurrence is common even after successful treatment. If thrush returns repeatedly, tell your GP, as they may want to review your management or check for other contributing factors such as diabetes.
Is it safe for my partner to be treated too?
Thrush is not classed as a sexually transmitted infection, but if your partner has symptoms such as itching or soreness, they can usually use an appropriate antifungal cream themselves. Speak to a pharmacist for guidance on suitable products.
