Usage
Beclometasone + Miconazole is prescribed for inflammatory skin disorders complicated by fungal infections. These include conditions like:
- Tinea infections (ringworm, athlete’s foot, jock itch): Fungal infections affecting various parts of the body.
- Eczema: An inflammatory skin condition causing redness, itching, and dryness.
- Dermatitis: Inflammation of the skin.
- Psoriasis: A skin disease that causes rapid skin cell buildup, resulting in red, scaly patches.
Pharmacological Classification: This is a combination product containing a corticosteroid (Beclometasone) and an antifungal (Miconazole).
Mechanism of Action: Beclometasone reduces inflammation by suppressing the immune response and inhibiting the production of inflammatory mediators. Miconazole inhibits fungal growth by disrupting the synthesis of ergosterol, a vital component of the fungal cell membrane.
Alternate Names
There are no widely recognized alternate names for the combination product itself. However, it’s important to note that the individual components have several names and forms:
- Beclometasone: Often seen as Beclomethasone Dipropionate.
- Miconazole: Available in various formulations (cream, ointment, powder, oral gel, vaginal suppositories).
Brand Names: Beclomin, Mycomin (in some regions). Brand names may vary depending on the country and manufacturer.
How It Works
Pharmacodynamics: Beclometasone exerts its anti-inflammatory effects by binding to glucocorticoid receptors in the skin cells. This leads to decreased production of inflammatory mediators (prostaglandins, leukotrienes, cytokines). Miconazole inhibits the fungal cytochrome P450 enzyme lanosterol 14α-demethylase, preventing the conversion of lanosterol to ergosterol. This weakens the fungal cell membrane, leading to cell leakage and fungal death.
Pharmacokinetics:
- Beclometasone (Topical): Minimally absorbed systemically when applied to intact skin. Absorption increases with damaged skin, prolonged use, or application to large areas. Metabolized primarily in the liver and excreted in urine and feces.
- Miconazole (Topical): Limited systemic absorption through the skin. Metabolized in the liver and excreted primarily in feces.
Dosage
Standard Dosage
Adults: Apply a thin layer to the affected area twice daily, usually in the morning and evening. Treatment duration depends on the condition and its severity (typically 1-2 weeks).
Children: Use in children younger than 17 years old is generally not recommended unless specifically directed by a physician due to the potential for increased systemic absorption of the corticosteroid component.
Special Cases:
- Elderly Patients: Use with caution. Monitor for signs of skin thinning and other adverse effects.
- Patients with Renal Impairment: Caution advised. Systemic absorption of Beclometasone can occur, potentially impacting patients with kidney disease.
- Patients with Hepatic Dysfunction: Caution advised, as both Beclometasone and Miconazole are metabolized in the liver.
- Patients with Comorbid Conditions: Assess potential drug interactions and adjust dosage accordingly.
Clinical Use Cases
This medication is not typically used in the clinical settings mentioned (intubation, surgical procedures, mechanical ventilation, ICU, emergency situations). Its usage is primarily limited to topical treatment of skin infections.
Dosage Adjustments
Dosage adjustments may be necessary based on patient response and the severity of the condition. If symptoms worsen or do not improve within the expected timeframe, consult a dermatologist.

Drug Interactions
- Warfarin: Topical corticosteroids may enhance the anticoagulant effects of warfarin. Monitor INR closely.
- Other Topical Medications: Avoid concomitant use of other topical medications on the affected area unless advised by a physician.
- Systemically Administered Antifungals (e.g., Ketoconazole, Itraconazole): May increase the risk of systemic side effects from Miconazole if used concurrently, although rare with topical application.
Pregnancy and Breastfeeding
The safety of Beclometasone + Miconazole during pregnancy and breastfeeding has not been fully established. Use only if the potential benefit outweighs the potential risk to the fetus or nursing infant. Consult a physician before use.
