Brand Name: Flonase, Flovent, Cutivate, generics

Drug Group: Corticosteroid (anti-inflammatory, antiallergic)

Commonly Used For

• Treat allergic rhinitis.

Key Characteristics

Form: Nasal spray (50 mcg/spray), inhalation powder (44 mcg, 110 mcg, 220 mcg), or topical cream/ointment (0.05%) (detailed in Dosage section).

Mechanism: Binds to glucocorticoid receptors, suppressing inflammatory cytokines.

Indications and Uses of Fluticasone

Fluticasone is indicated for a range of inflammatory and allergic conditions, leveraging its potent anti-inflammatory properties:

Allergic Rhinitis: Alleviates nasal congestion, sneezing, and itching caused by seasonal or perennial allergens, per allergy guidelines, supported by clinical trials showing symptom relief within 12–24 hours.

Asthma: Controls chronic inflammation and prevents exacerbations in persistent asthma, improving lung function, recommended in pulmonary medicine protocols.

Eczema (Atopic Dermatitis): Reduces itching and inflammation on the skin, enhancing quality of life, with dermatology evidence.

Chronic Obstructive Pulmonary Disease (COPD): Manages inflammation in stable COPD, reducing exacerbations, per respiratory health studies.

Nasal Polyps: Treats inflammation and shrinkage of nasal polyps, improving airflow, with otolaryngology data.

Contact Dermatitis: Investigated off-label to relieve irritation from irritants or allergens, with occupational dermatology research.

Eosinophilic Esophagitis: Explored off-label to reduce esophageal inflammation, with gastroenterology evidence.

Chronic Rhinosinusitis: Used off-label to manage persistent sinus inflammation, with ENT studies.

Psoriasis (Mild): Initiated off-label for localized plaques, with dermatology research.

Allergic Bronchopulmonary Aspergillosis (ABPA): Managed off-label to control allergic responses in asthmatics, with pulmonary medicine data.

Dosage of Fluticasone

Dosage for Adults

Allergic Rhinitis: Nasal Spray (Flonase): 2 sprays (50 mcg each) per nostril once daily (total 200 mcg), reduced to 1 spray per nostril after symptom control.

Asthma: Inhalation Powder (Flovent): 88–440 mcg twice daily, adjusted based on asthma severity and peak flow measurements.

Eczema: Topical Cream/Ointment (Cutivate): Apply a thin layer to affected area 1–2 times daily for up to 4 weeks.

Dosage for Children

Allergic Rhinitis (4–11 years): Nasal Spray: 1 spray (50 mcg) per nostril once daily (total 100 mcg), increased to 2 sprays if needed, under pediatric supervision.

Asthma (4–11 years): Inhalation Powder: 88 mcg twice daily, titrated based on symptom control.

Eczema (3–17 years): Topical Cream: Apply once daily for up to 2 weeks, monitored for skin thinning.

Dosage for Pregnant Women

Pregnancy Category C: Use only if benefits outweigh risks; consult an obstetrician, with fetal monitoring.

Dosage Adjustments

Renal Impairment: No adjustment needed; monitor for systemic absorption in severe cases.

Hepatic Impairment: Mild to moderate (Child-Pugh A or B): Reduce frequency; severe (Child-Pugh C): Avoid due to metabolism concerns.

Concomitant Medications: Adjust if combined with CYP3A4 inhibitors (e.g., ketoconazole), increasing levels; monitor.

Elderly: Start with lower doses; monitor for adrenal suppression.

Additional Considerations

• Administer this active ingredient as prescribed, priming nasal spray before first use (6–10 pumps) and shaking inhalation device.
• Rinse mouth after inhalation to reduce oral thrush risk.

How to Use Fluticasone

Administration:

Nasal Spray: Tilt head slightly forward, insert nozzle into nostril, spray while breathing in gently, repeat for other nostril.

Inhalation: Use a spacer with metered-dose inhaler, exhale fully, inhale deeply, hold breath for 10 seconds.

Topical: Apply a thin layer to clean, dry skin, rubbing gently until absorbed.

Timing: Use at consistent times daily, preferably morning and evening for inhalation.

Monitoring: Watch for nasal irritation, hoarseness, or signs of infection (e.g., white patches in mouth).

Additional Tips:

• Store at 20–25°C (68–77°F), protecting from light and freezing.
• Keep out of reach of children due to corticosteroid risk.
• Clean inhaler weekly with warm water to prevent clogging.
• Avoid spraying nasal spray into eyes or mouth; use protective eyewear if needed.
• Report persistent symptoms (e.g., wheezing, skin rash) immediately to a healthcare provider.

Contraindications for Fluticasone

Hypersensitivity: Patients with a known allergy to Fluticasone or other corticosteroids.

Status Asthmaticus: Contraindicated as a primary treatment due to delayed onset.

Untreated Infections: Avoid in active tuberculosis or untreated fungal/bacterial infections.

Severe Hepatic Impairment: Contraindicated in Child-Pugh Class C due to metabolism issues.

Ocular Herpes Simplex: Avoid topical use near eyes with active infection.

Warnings & Precautions for Fluticasone

General Warnings

Adrenal Suppression: Risk with high doses or prolonged use; monitor cortisol levels.

Immunosuppression: Increased risk of infections (e.g., Candida); assess regularly.

Glaucoma/Cataracts: Risk with nasal/inhalation use; monitor eye pressure.

Growth Retardation: Risk in children with long-term use; monitor height.

Hypersensitivity Reactions: Rare anaphylaxis; discontinue if severe.

Additional Warnings

Osteoporosis: Risk with chronic systemic absorption; assess bone density.

Hyperglycemia: Risk in diabetic patients; monitor glucose.

Psychiatric Effects: Rare mood changes; evaluate mental health.

Skin Atrophy: Risk with prolonged topical use; limit to 4 weeks.

Pulmonary Tuberculosis: Risk of reactivation; screen before use.

Use in Specific Populations

Pregnancy: Category C; use with caution and monitoring.

Breastfeeding: Use caution; monitor infant for hormonal effects.

Elderly: Higher risk of adrenal suppression; start low and monitor.

Children: Safe for short-term use with supervision.

Renal/Hepatic Impairment: Adjust or avoid in severe cases.

Additional Precautions

• Inform your doctor about diabetes, infections, or liver disease before starting this medication.
• Avoid abrupt discontinuation to prevent adrenal crisis.

Overdose and Management of Fluticasone

Overdose (from excessive use) may cause:

Nasal irritation, throat discomfort, or hoarseness.

Severe cases: Adrenal insufficiency, Cushing’s syndrome, or hyperglycemia.

Headache, fatigue, or weight gain as early signs.

Coma or profound electrolyte imbalance with extremely high exposure.

Immediate Actions

Contact the Medical Team: Seek immediate medical help if systemic symptoms occur.

Supportive Care: Monitor vital signs, provide hydration, and assess cortisol levels.

Specific Treatment: No specific antidote; taper dose and manage symptoms (e.g., hydrocortisone for adrenal crisis).

Monitor: Check adrenal function, glucose, and mental status for 24–48 hours.

Additional Notes

• Overdose risk is low with proper use; store securely and limit access.
• Report persistent symptoms (e.g., severe fatigue, swelling) promptly.

Side Effects of Fluticasone
