Understanding Xemacort Cream
Xemacort is a prescription medication indicated for the treatment of inflammatory skin conditions, such as eczema and dermatitis, where a bacterial infection is also present. It is not intended for skin conditions caused solely by fungal or viral infections, like athlete's foot or cold sores. The treatment course with Xemacort should typically not go beyond two weeks to minimize the risk of side effects. This medication is only available with a doctor's prescription.
The Dual-Action Pharmacology of Xemacort
Xemacort's effectiveness comes from its two active ingredients that work simultaneously:
-
Betamethasone (as valerate): This is a potent corticosteroid, which is a synthetic version of a hormone naturally produced by the body. Its primary role is anti-inflammatory. Betamethasone works by activating natural substances in the skin to reduce swelling, redness, and itching associated with conditions like eczema and psoriasis. It is stronger than milder steroids like hydrocortisone and is often prescribed when other treatments have not been effective.
-
Fusidic Acid: This is an antibiotic that works by stopping the growth of germs (bacteria) that cause skin infections. It is particularly effective against staphylococcal bacteria, which can cause conditions like infected dermatitis and impetigo. By eliminating the bacteria, fusidic acid helps to clear the infection, allowing the inflamed skin to heal.
How to Use Xemacort Cream
Xemacort cream should always be used exactly as prescribed by your doctor. It is for external (cutaneous) use only.
- Application: A small, thin film of the cream should be applied to the affected area as directed by a healthcare professional.
- Hygiene: Always wash your hands before and after applying the cream, unless you are treating your hands.
- Sensitive Areas: Avoid getting the cream in your eyes, mouth, or on sensitive areas like genitals, armpits, or open wounds unless specifically directed by your doctor. Accidental contact with eyes can lead to increased pressure and potentially glaucoma.
- Dressings: Do not cover the treated area with bandages or dressings unless advised by your healthcare provider, as this can increase the absorption of the steroid into the body and raise the risk of side effects.
Potential Side Effects and Precautions
Like all medications, Xemacort can cause side effects. Common, localized side effects include a mild burning or stinging sensation, itching, or dryness at the application site.
Long-term or excessive use of potent topical steroids like betamethasone can lead to more serious side effects:
- Skin Changes: Thinning of the skin (atrophy), stretch marks, bruising easily, and changes in skin color.
- Systemic Effects: Though rare with topical use, the steroid can be absorbed into the bloodstream, potentially leading to Cushing's syndrome or adrenal gland problems. Symptoms can include unusual tiredness, weight changes, and high blood sugar.
- Vision Problems: Using the cream near the eyes can increase the risk of cataracts or glaucoma. Report any blurred vision or other vision changes to your doctor immediately.
- Topical Steroid Withdrawal: After prolonged use, stopping the cream can lead to a rebound flare, with intense redness and burning that may spread beyond the original treatment area.
It is contraindicated for use in infants under one year of age and for conditions like acne, rosacea, or perioral dermatitis (a rash around the mouth).
Comparison of Topical Skin Creams
| Cream Type | Active Ingredient(s) | Primary Use | Mechanism | Example Brand(s) |
|---|---|---|---|---|
| Combination (Steroid + Antibiotic) | Betamethasone, Fusidic Acid | Inflamed, infected eczema/dermatitis | Reduces inflammation and kills bacteria | Xemacort, Fucibet |
| Potent Steroid Only | Betamethasone | Severe eczema, psoriasis, dermatitis (non-infected) | Reduces inflammation, redness, and itching | Betnovate, Diprosone |
| Combination (Steroid + Antifungal) | Betamethasone, Clotrimazole | Fungal infections with inflammation (e.g., athlete's foot) | Reduces inflammation and kills fungi | Lotrisone |
| Antibiotic Only | Fusidic Acid | Bacterial skin infections (e.g., impetigo) | Kills bacteria causing the infection | Fucidin |
Conclusion
Xemacort cream is a highly effective, prescription-only medication that treats eczematous dermatoses that have become bacterially infected. Its combination of a potent steroid (betamethasone) and a powerful antibiotic (fusidic acid) allows it to simultaneously manage inflammation and fight infection. However, due to the potency of its steroid component, it must be used with care, strictly following a doctor's instructions and for limited durations to avoid significant side effects. Always consult a healthcare professional for diagnosis and treatment of any skin condition.
