Understanding Canesten Creams
Canesten, a well-known brand for treating candidal infections, utilizes the antifungal agent clotrimazole in its creams. Fungal infections, such as thrush, are caused by an overgrowth of yeast (Candida) and manifest with both internal and external symptoms. The Canesten product line is designed to tackle these symptoms comprehensively by offering specialized creams for each area. The choice between an internal, external, or combination cream depends on the specific symptoms and their location. All Canesten creams containing clotrimazole work by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes, leading to the death of the fungal cells.
Canesten Internal Cream: Targeting the Source
Canesten internal cream is specifically formulated for treating the root cause of a vaginal yeast infection. The cream is designed to be inserted directly into the vagina to combat the fungal overgrowth at the site of infection.
- Purpose: To cure the underlying vaginal fungal infection, which causes symptoms like abnormal discharge and internal discomfort.
- Active Ingredient & Strength: The internal cream contains a high concentration of clotrimazole. For instance, the 1-day internal cream contains 10% w/w clotrimazole in a single-dose applicator. Longer-course treatments, such as the 3-day or 6-day creams, contain lower concentrations (2% and 1% respectively), which are inserted over a period of consecutive days.
- Application Method: An included single-use, pre-filled applicator is used to insert the cream as deeply as possible into the vagina, typically at bedtime. This reduces leakage and allows the medication to work effectively overnight.
Canesten External Cream: Soothing the Symptoms
In contrast to the internal treatment, Canesten external cream is used for symptomatic relief. It is not designed to cure the internal infection but rather to alleviate the uncomfortable external symptoms that accompany it.
- Purpose: To relieve external vulval symptoms, such as itching, burning, soreness, and irritation.
- Active Ingredient & Strength: External cream typically has a lower concentration of clotrimazole, often 1% or 2%. Some formulations may include an anti-inflammatory agent like hydrocortisone for enhanced soothing.
- Application Method: The cream is applied thinly and evenly to the irritated external area, such as the vulva, two or three times a day. It is massaged in gently until it disappears into the skin.
- Additional Uses: External cream can also be used by a male partner to prevent re-infection if he is experiencing symptoms of penile thrush.
Combination Packs: A Complete Treatment
For many women, thrush involves both internal and external discomfort. Canesten offers combination packs that contain both an internal treatment (either a pessary or internal cream) and a tube of external cream. These packs provide a comprehensive two-step solution:
- Internal Treatment: Targets the infection at its source to cure it completely.
- External Cream: Offers fast and effective relief for the immediate, irritating symptoms on the outside.
Using a combination pack ensures that both the underlying cause and the surface symptoms are addressed, providing complete relief. Patients can choose between 1-day, 3-day, or 6-day combination packs depending on their preference for treatment duration.
The Key Differences: A Comparison Table
| Feature | Canesten Internal Cream | Canesten External Cream |
|---|---|---|
| Primary Purpose | Cures the internal vaginal yeast infection. | Relieves external vulval symptoms like itching and burning. |
| Application Area | Inside the vagina only. | Outside on the vulva and surrounding irritated skin. |
| Delivery Method | Pre-filled, disposable applicator for insertion. | Topical application with a fingertip. |
| Clotrimazole Strength | Higher concentration (e.g., 10% for 1-day). | Lower concentration (e.g., 1-2%). |
| Typical Dosage | Single dose (1-day) or multi-day courses (3-day, 6-day). | 2-3 times daily, as needed. |
| Treatment Focus | Addresses the fungal cause of the infection. | Manages the discomfort and irritation associated with the infection. |
Important Considerations for Treatment
Choosing the Right Product
- Internal Symptoms Only: If you have minimal or no external itching, a single internal cream or pessary may suffice.
- External Symptoms Only: For external symptoms, the external cream is used for soothing relief. It will not cure an internal infection.
- Both Internal & External Symptoms: For complete relief from both the cause and the symptoms, a combination pack is the most effective option.
Before and During Treatment
- Consult a Doctor: It is advisable to consult a doctor or pharmacist, especially if it is your first time experiencing thrush symptoms, you are under 16 or over 60, pregnant, have a history of STDs, or have recurrent infections.
- Contraceptive Warning: Clotrimazole creams can temporarily reduce the effectiveness of latex contraceptives (condoms and diaphragms). Use alternative contraception for at least five days after treatment.
- Personal Hygiene: Maintain good hygiene practices and wear loose-fitting cotton underwear to help prevent further irritation and re-infection. Avoid perfumed soaps, bath additives, and vaginal deodorants during and after treatment.
Conclusion
The fundamental difference between Canesten internal and external cream is their intended site of action. Internal cream, delivered via an applicator, is a curative treatment for the vaginal yeast infection itself, often in a higher concentration of clotrimazole. External cream, applied topically, is a soothing treatment for the bothersome external symptoms, with a lower clotrimazole concentration. For most comprehensive relief, particularly when both internal and external symptoms are present, a combination pack containing both types of cream is the recommended solution. Always follow the product instructions carefully and consult a healthcare professional with any concerns.
