Usage
Fluticasone Propionate + Mupirocin is prescribed for the treatment of inflammatory skin disorders complicated by secondary bacterial infections, such as eczema, psoriasis, and allergic contact dermatitis with impetigo.
-
Pharmacological Classification: This is a combination product containing a corticosteroid (fluticasone propionate) and a topical antibiotic (mupirocin).
-
Mechanism of Action: Fluticasone propionate reduces inflammation and itching by binding to glucocorticoid receptors, inhibiting the production of inflammatory mediators like prostaglandins and leukotrienes. Mupirocin inhibits bacterial protein synthesis by targeting isoleucyl-tRNA synthetase, effectively combating bacterial infections like Staphylococcus aureus and Streptococcus pyogenes.
Alternate Names
There are no widely recognized alternate names for the combination product itself, although regional variations may exist. “Flutibact Skin Ointment” is one known brand name. Other brand names may also exist.
How It Works
-
Pharmacodynamics: Fluticasone propionate exerts its anti-inflammatory and antipruritic effects by binding to glucocorticoid receptors in the skin cells. Mupirocin acts as a topical antibacterial agent by selectively inhibiting isoleucyl-tRNA synthetase in susceptible bacteria, leading to the cessation of protein synthesis and bacterial death.
-
Pharmacokinetics: Fluticasone propionate, when applied topically, is minimally absorbed into the systemic circulation. Absorption can increase if applied to large areas, broken skin, or under occlusion. Metabolized primarily in the liver and excreted through the bile. Mupirocin is minimally absorbed systemically following topical application to intact skin. If absorbed, it is rapidly metabolized to the inactive monic acid and excreted primarily in the urine.
-
Mode of Action (Cellular/Molecular): Fluticasone propionate binds to glucocorticoid receptors within skin cells. This receptor binding translocates to the nucleus and modulates the transcription of various genes involved in the inflammatory response. Consequently, the production of inflammatory mediators is reduced. Mupirocin specifically binds to bacterial isoleucyl-tRNA synthetase, preventing the incorporation of isoleucine into bacterial proteins.
-
Elimination Pathways: Primarily hepatic metabolism and biliary excretion for fluticasone propionate. Renal excretion for mupirocin.
Dosage
Standard Dosage
Adults: Apply a thin film to the affected area twice daily for up to 10 days. Treatment should be re-evaluated if the condition worsens or doesn’t improve within this timeframe.
Children: Application for children aged 3 months and older is generally considered safe under the guidance of a physician. Dosing similar to adults, though the treated area should be minimized. For children younger than 3 months, consult a pediatrician.
Special Cases:
-
Elderly Patients: Start with the lowest effective dose. Monitor for local and systemic side effects.
-
Patients with Renal Impairment: Systemic absorption is minimal; hence dose adjustment is not typically required. Monitor carefully for any signs of systemic absorption.
-
Patients with Hepatic Dysfunction: Dose adjustments may be necessary. Close monitoring is recommended.
-
Patients with Comorbid Conditions: Individualized treatment plans are needed based on the coexisting condition. Caution is advised, especially for patients with diabetes or conditions affecting skin integrity.
Clinical Use Cases
The combination of fluticasone propionate and mupirocin is not typically used in the clinical scenarios listed (Intubation, Surgical Procedures, Mechanical Ventilation, ICU Use, Emergency Situations). It is primarily indicated for topical treatment of specific dermatological conditions with secondary bacterial infection.
Dosage Adjustments
Dosage adjustments might be required for patients with renal or hepatic impairment, or those using interacting medications. Always consult with a specialist in such cases.
Side Effects
Common Side Effects:
Burning, itching, stinging, dryness, and irritation at the application site.
Rare but Serious Side Effects:
Allergic contact dermatitis, skin atrophy, telangiectasia, hypopigmentation with prolonged use.
Long-Term Effects:
Skin thinning, striae, and telangiectasia may occur with prolonged or high-dose use, especially under occlusion.
Adverse Drug Reactions (ADR):
Severe allergic reactions are rare but may include skin rash, urticaria, facial swelling, and difficulty breathing.
Contraindications
Hypersensitivity to fluticasone propionate or mupirocin. Untreated viral, fungal, or tuberculous skin infections. Rosacea, acne vulgaris, perioral dermatitis. Infants under 3 months of age.
Drug Interactions
Inform patients to disclose all medications, including OTC and herbal products. While systemic absorption is limited, interactions with ritonavir or itraconazole may occur. Co-administration with other topical agents on the same area should be avoided unless specifically directed by a physician.
Pregnancy and Breastfeeding
-
Pregnancy: Use only if clearly needed. Discuss the risks and benefits with the patient.
-
Breastfeeding: Advise patients to avoid applying to the nipple area before breastfeeding. Safety data is limited.

FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Fluticasone Propionate + Mupirocin?
A: Apply a thin film to the affected skin area twice daily for up to 10 days. Consult a physician if no improvement is observed within this period.
Q2: Can Fluticasone Propionate + Mupirocin be used on the face?
A: Generally, it’s best to avoid facial application unless specifically directed by a physician. The skin on the face is thinner and more prone to side effects.
Q3: How should the affected area be prepared before applying the ointment?
A: Gently cleanse the affected area with a mild cleanser and pat dry before applying the ointment.
Q4: Can this ointment be used for all types of skin infections?
A: No. It is specifically designed for inflammatory skin conditions with secondary bacterial infection. It should not be used for primary viral, fungal, or tuberculous infections.
Q5: What are the signs of an allergic reaction to this medication?
A: Increased redness, itching, swelling, or a spreading rash at or beyond the application site. Rarely, more serious reactions like hives, facial swelling, and difficulty breathing may occur.
Q6: Can I cover the treated area with a bandage?
A: Generally, avoid using occlusive dressings unless directed by a doctor. Occlusion can increase absorption and the risk of side effects.
Q7: Can I stop using the ointment once the symptoms improve?
A: It’s essential to complete the prescribed course of treatment, even if symptoms improve, unless advised otherwise by a physician. Premature discontinuation may lead to recurrence of the infection.
Q8: What should I do if I accidentally apply the ointment to my eyes or mouth?
A: Rinse thoroughly with water. If irritation persists, consult a doctor.
Q9: Can I use this ointment alongside other topical medications?
A: Avoid concomitant use of other topical products on the same area unless directed by a physician. Certain combinations might interact or reduce efficacy.
Q10: Are there any precautions for pregnant or breastfeeding women?
A: Consult a physician before using this ointment during pregnancy or while breastfeeding. Safety data during these periods is limited. If use is deemed necessary, it should be for the shortest duration possible.
