Dupixent 300 Mg Injection

*Dupixent (dupilumab) Injection - Use & Benefits*

This is a prescription biologic made by Sanofi Genzyme / Regeneron. The box shows *300 mg/2 mL*, single-dose pre-filled syringes, for subcutaneous use only.

*What it is*

Dupixent is a monoclonal antibody that blocks IL-4 and IL-13 signaling — two key drivers of Type 2 inflammation.

*Approved uses*

It’s an FDA-approved prescription drug for specific inflammatory conditions:

Condition Typical patient group

**Atopic dermatitis** Moderate-to-severe eczema in adults & children 6 months+, when topical treatments aren’t enough

**Asthma** Moderate-to-severe eosinophilic or oral steroid-dependent asthma, age 6+ as add-on maintenance

**Chronic rhinosinusitis with nasal polyps** Adults, as add-on therapy when nasal sprays aren’t enough

**Eosinophilic esophagitis (EoE)** Age 1+ years, weighing ≥15 kg

**Prurigo nodularis** Adults with moderate-to-severe itchy nodules

*How it helps*

By calming Type 2 inflammation, patients often see:

1. *Eczema*: Reduced itch, clearer skin, fewer flares

2. *Asthma*: Fewer exacerbations, better lung function, reduced steroid need

3. *Nasal polyps*: Smaller polyps, less congestion, better smell

4. *EoE*: Less trouble swallowing, reduced eosinophils in the esophagus

*Important notes*

1. *Rx only*: This is a prescription biologic. It must be prescribed and monitored by a doctor.

2. *Storage*: Refrigerate at 2°C to 8°C. Can be kept at room temp <25°C for up to 14 days.

3. *Side effects*: Injection site reactions, eye problems like conjunctivitis, cold sores, joint pain. Rare risk of hypersensitivity.

4. *Not for acute issues*: Doesn’t treat acute asthma attacks or sudden eczema flares — it’s maintenance therapy.

Because Dupixent is a prescription-only biologic with specific indications and safety monitoring, talk to your dermatologist, pulmonologist, or relevant specialist to see if it’s appropriate for your condition.
