Understanding Canesten Internal Cream
Canesten internal cream is an over-the-counter medication designed to combat the underlying cause of vaginal thrush: a fungal overgrowth. Vaginal thrush, or candidiasis, is a common condition resulting from an imbalance of the naturally occurring yeast called Candida in the vagina. This imbalance can be triggered by various factors, including hormonal changes, antibiotic use, or a weakened immune system. The cream, delivered via a pre-filled applicator, treats the infection at its source to alleviate uncomfortable symptoms.
The Active Ingredient: Clotrimazole
The active substance in Canesten internal cream is clotrimazole, an antifungal agent belonging to the azole class of medicines. Clotrimazole works by damaging the cell membrane of the Candida fungus, leading to its death and clearing the infection. Following vaginal application, only a small amount of clotrimazole is absorbed systemically, minimizing the risk of widespread side effects. This targeted approach ensures that the medication is concentrated where it is most needed, directly at the site of the infection.
Indications: When to Use Canesten Internal Cream
Canesten internal cream is specifically for the treatment of vulvovaginal candidiasis. It is effective against the key symptoms associated with this condition, which can include:
- Persistent itching and burning around the vagina and vulva
- Redness and swelling of the vaginal tissues
- Soreness in the intimate area
- A whitish, thick, and odorless vaginal discharge
It is crucial to correctly identify the cause of your symptoms. Canesten internal cream is ineffective against bacterial vaginosis (BV), another common vaginal infection. BV is caused by bacteria, not fungus, and presents with different symptoms, most notably a foul-smelling, watery, greyish discharge. If you are unsure whether you have thrush or another condition, it is best to consult a doctor before starting treatment.
How to Use Canesten Internal Cream
Canesten internal cream is typically used as a short-course treatment, available in 1-day, 3-day, or 6-day formats with varying concentrations of clotrimazole. For best results, follow these general instructions:
- Preparation: Wash your hands thoroughly before and after use. The applicator is pre-filled for convenience.
- Insertion: Lying on your back with your knees bent, insert the applicator as deeply and comfortably as possible into the vagina.
- Application: Slowly push the plunger until it stops to release the cream. This is best done at bedtime to allow the medication to work overnight and to minimize leakage.
- Leakage: Some leakage is normal. Using a panty liner can protect your clothing and is recommended during the treatment period.
- Completion: Continue the full course of treatment even if symptoms improve quickly to ensure the infection is fully cleared.
Combination Products for Complete Relief
For women with both internal and external thrush symptoms, Canesten offers "Combi Packs". These kits include the internal cream to treat the source of the infection and a separate external cream to provide additional, rapid relief from itching and burning on the vulva.

Potential Side Effects and Precautions
While generally well-tolerated, Canesten internal cream can cause some side effects.
Common side effects include:
- Burning or stinging sensation
- Mild irritation, redness, or itching
- Abdominal cramping or bloating
Important precautions:
- The cream can damage the latex used in contraceptives like condoms and diaphragms, reducing their effectiveness. Use alternative birth control for at least five days after treatment.
- Do not use during your period, as it may be less effective.
- Do not use tampons, douches, or other vaginal products during treatment.
- Seek medical attention immediately if you experience signs of an allergic reaction, such as a severe rash, swelling, or difficulty breathing.
When to See a Doctor
Consulting a healthcare professional is recommended in several scenarios, including:
- If this is your first time experiencing thrush symptoms.
- If symptoms do not improve within seven days of treatment or recur more than twice in six months.
- If you have concerning symptoms like irregular bleeding, foul-smelling discharge, abdominal pain, or fever.
- If you are pregnant or breastfeeding.
- Using antifungal treatments unnecessarily can lead to drug resistance over time.
Conclusion
Canesten internal cream provides an effective, targeted treatment for vaginal yeast infections caused by Candida. By using the active ingredient clotrimazole, it works directly at the source of the infection to relieve common symptoms like itching and burning. Choosing the right Canesten product, following the instructions carefully, and being aware of potential side effects and precautions are key for successful treatment. Remember to consult a healthcare provider for an accurate diagnosis, especially if you are unsure of your condition or if symptoms persist, to ensure you receive the most appropriate and safe treatment.
