Understanding Dupixent Uses and Dosages
Dupixent, known generically as dupilumab, has become a vital treatment option for people suffering from moderate-to-severe atopic dermatitis (eczema), asthma, and chronic rhinosinusitis with nasal polyps. As a biologic therapy, it targets specific pathways in the immune system to reduce inflammation. Because Dupixent is a prescription medication administered via injection, understanding the correct dosage and schedule is essential for safety and effectiveness.

Dupixent Dosage by Condition
Atopic Dermatitis (Eczema)
For adults and adolescents 12 years and older with moderate-to-severe atopic dermatitis, the usual starting dose is a loading dose of 600 mg (two injections of 300 mg each). After this, a maintenance dose of 300 mg is given every two weeks. For children aged 6 to 11 years, dosing is weight-based:
15 to less than 30 kg: 300 mg every 4 weeks
30 kg or more: 300 mg every 2 weeks
Asthma
Adults and adolescents 12 years and older with moderate-to-severe eosinophilic or oral corticosteroid-dependent asthma typically receive a loading dose of 400 mg (two 200 mg injections) or 600 mg (two 300 mg injections), as determined by physician assessment. Maintenance dosing is 200 mg or 300 mg every two weeks. The exact dose depends on the severity and patient weight.
Chronic Rhinosinusitis with Nasal Polyps
The recommended dose for adults is a loading dose of 600 mg followed by 300 mg every two weeks. This dosing helps reduce nasal polyp size and improve nasal airflow.
What is the Typical Dupixent Dose for Adults?
Most adult patients start with a loading dose of 600 mg (two injections of 300 mg) to quickly build up medication levels in the body. Maintenance doses are then administered every two weeks at 300 mg. Some patients with asthma may receive 200 mg doses instead, based on their doctor’s evaluation.
Dupixent is injected under the skin, usually in the thigh, abdomen, or upper arm. Patients or caregivers are often trained to self-inject at home, making treatment convenient and less disruptive.
What is the Typical Dupixent Dose for Children?
Children aged 6 to 11 years receive weight-based dosing. Those weighing between 15 and 30 kg typically get 300 mg every four weeks, while children over 30 kg follow the adult dosing schedule of 300 mg every two weeks. Dupixent is not approved for children under 6 years old.
What to Do If You Miss a Dose of Dupixent?
If a dose is missed, take it as soon as you remember unless the next scheduled dose is within 7 days. In that case, skip the missed dose and resume your regular dosing schedule. Do not double up doses to catch up. If unsure, contact your healthcare provider or use Doctronic.ai to get quick advice from a medical professional.
How to Adjust Your Dupixent Dose for Certain Medical Conditions
Kidney or Liver Issues
Currently, no specific dose adjustments are recommended for patients with mild to moderate kidney or liver impairment. However, patients with severe organ dysfunction should consult their healthcare provider before starting Dupixent.
Other Immune Conditions
Because Dupixent affects the immune system, patients with other immune-related conditions or infections should discuss risks and benefits with their doctors. Dose adjustments may be necessary based on individual health status.
Dupixent Overdose and Warnings
There is limited data on Dupixent overdose, but taking more than the prescribed dose is not advised. Overdose symptoms could include increased side effects such as injection site reactions, eye inflammation, or allergic reactions. Seek immediate medical attention if an overdose is suspected.
Patients should inform their healthcare providers about all medications and supplements they are taking, as Dupixent may interact with other treatments. Regular monitoring is essential to ensure safety and effectiveness.
Tips for Taking Dupixent Safely
Follow the prescribed dosing schedule carefully.
Store Dupixent in the refrigerator and protect it from light.
Do not shake the injection pen or syringe.
Rotate injection sites to avoid irritation.
Report any side effects or unusual symptoms to your healthcare provider promptly.
