Defuzin-B Cream

Defuzin-B Cream is a combination topical preparation containing Clotrimazole, an antifungal agent, together with Betamethasone, a corticosteroid, as its active ingredients. This combination is used to treat fungal skin infections such as tinea (ringworm), athlete’s foot, and jock itch that are accompanied by significant inflammation, redness, and itching, as the corticosteroid component provides faster symptomatic relief while the antifungal clears the underlying infection.

Because it contains a corticosteroid alongside an antifungal, Defuzin-B Cream is classified as a prescription-only medicine in Malaysia and Singapore. It is supplied by DoctorOnCall only after an online consultation, during which a doctor confirms the diagnosis and appropriateness of combination therapy, since inappropriate or prolonged steroid-antifungal combination use can mask or worsen certain skin infections and cause skin thinning.

Clotrimazole works by disrupting the fungal cell membrane, leading to leakage of essential cellular contents and death of the fungal organism, while Betamethasone suppresses the local immune and inflammatory response by binding to glucocorticoid receptors in skin cells. Together, this combination rapidly reduces the itching, redness, and swelling caused by the fungal infection while the antifungal component works to eliminate the causative organism.

Defuzin-B Cream should be used strictly as directed by the prescribing doctor. A thin layer is usually applied to the clean, affected area and surrounding skin twice daily, gently rubbed in, with hands washed afterwards. Treatment is generally limited to a short period, typically no more than one to two weeks, after which the doctor may switch to an antifungal-only product to complete the full antifungal course without continued steroid exposure.

The frequency and duration of Defuzin-B Cream use are determined by the prescribing doctor based on the site, severity, and extent of the fungal infection and inflammation. Due to the corticosteroid component, use is typically restricted to a short course of about one to two weeks, with follow-up review before any continuation or switch to a non-steroid antifungal preparation.

Defuzin-B Cream is generally stable for up to 24 to 36 months from the date of manufacture when unopened and stored correctly; the exact expiry date is printed on the tube and outer packaging. Do not use the cream beyond its stated expiry date.

Store Defuzin-B Cream below 30°C in a cool, dry place away from direct sunlight and moisture. Keep the tube tightly closed after each use and out of reach of children.

• Untreated bacterial or viral skin infections at the application site
• Use on the face without specific doctor guidance
• Prolonged or continuous use beyond the prescribed period
• Use in children without direct medical supervision

• Concurrent use with other topical corticosteroids may increase the risk of skin thinning and systemic absorption
• Use with occlusive dressings can increase drug absorption and side effects
• Combining with other topical antifungals or irritants may alter local skin response
• No significant food interactions are expected with topical use

• Use only for the duration advised by your doctor, even if symptoms improve quickly
• Apply a thin layer to the affected area and slightly beyond its edges
• Keep the area clean and dry between applications where possible
• Do not use on the face or in skin folds unless specifically instructed
• Return to your doctor for follow-up to assess whether continued antifungal-only treatment is needed
• Do not share this cream with others, even for similar-looking rashes

Defuzin-B Cream combines an antifungal with a corticosteroid and is intended for short-term use only, as prolonged steroid exposure can worsen fungal infections or cause skin thinning. Patients should follow up with their doctor once the inflammatory symptoms settle, as treatment is often switched to an antifungal-only cream to complete clearance of the fungal infection safely.
