The Dupixent Pre-filled Pen is designed for self-administration at home, so it’s easy to incorporate into your routine. Here’s a step-by-step guide on how to do it:

Preparation:

• Take the pen out of the refrigerator at least 30 minutes before using it so that it has time to come to room temperature.
• Gently wash your hands with soap and water.
• Draw a flat, even surface and everything that you will require for the injection.

Injection Site:

• The injection has to be made subcutaneously in the skin of the thigh or abdomen. Do not inject the shot into areas of bruised, red, or other skin condition areas.
• Choose another site of injection each time to reduce the risk of irritation.

Injecting

• Remove the pen from the protective case and consult the instructions on how to prime the pen.
• Pinch your skin lightly at the chosen injection site.
• Place the pen firmly against your skin and press the button to inject the medication.
• The pen will deliver the dose automatically. Remove the pen from your skin once used.

Post-Injection:

• Dispose of the pen properly in a sharps container after use.
• Do not reuse the pen.
• Wash your hands once more after disposal.
• Missed Dose: If you forget a dose, call your healthcare provider to determine what to do. Do not take two doses at once.

• The Dupixent Pre-filled Pen works by inhibiting and blocking two proteins of the immune system, interleukin-4 (IL-4) and interleukin-13 (IL-13), which play a central role in inflammatory disease. By inhibiting them, Dupixent inhibits inflammation that leads to redness, itchiness, breathlessness, and swelling.
• IL-4 and IL-13: These proteins are utilized to induce inflammation in conditions like eczema, asthma, and nasal polyps. When these proteins are blocked, the body’s immune system is controlled, and reduced inflammation, along with improved symptoms, result.
• Dupixent: By selectively blocking IL-4 and IL-13, Dupixent addresses the root causes of eczema and asthma diseases, reducing flare-ups, healing the skin, and facilitating easy breathing for people with asthma.
• The pre-filled pen is a convenient method through which patients can administer their regular dosage, and they can be in charge of their illness with less effort.

Like any drug, Dupixent Pre-filled Pen can have side effects. The majority of the side effects are mild but some are serious. The following are the common and serious side effects:

Common Side Effects

• Injection site reactions: Pain, redness, swelling, or itching at the injection site.
• Eye problems: Dry eye, eye irritation, or conjunctivitis (pink eye) in some patients.
• Cold symptoms: Runny nose, sore throat, or cough.

Severe Side Effects:

• Allergic reactions: Occasionally, some people can have severe allergic reactions, including swelling of the face, lips, tongue, or throat, and shortness of breath. Call your doctor right away if you have these symptoms.
• Risk of infection: Because Dupixent affects the immune system, you may be put at risk for infection. Inform your doctor if you get a fever, chills, or a persistent cough.

Inform your doctor of any conditions you may have, especially if:

• You have problems with your eyes: Dupixent may increase your chance of having eye problems such as conjunctivitis or eye irritation.
• Pregnant or becoming pregnant: Talk with your doctor about the risks if you are pregnant or breastfeeding.
• Ever had infection: Dupixent will also slightly impair the immune system, so talk with your doctor about history of infections.
• Allergic to Dupixent or any Dupixent ingredient: Tell your healthcare provider if you are allergic to Dupixent or any Dupixent ingredient.

• Other medicines: Dupixent can also be used on occasion together with other medications like inhaled steroids for asthma or creams for eczema. Always inform your physician about other medications that you are using as Dupixent can interfere with some medications.
• Vaccinations: As Dupixent is an immunomodulator drug, live vaccinations should be avoided during therapy. Always see your physician prior to any vaccines.

• Dosage is condition-based at first. Take an initial big dose and a maintenance dose every two weeks for most of the conditions.
• Long-Term Use: Dupixent is a long-term drug, and it’s important to continue on the dosage prescribed to manage your symptoms adequately.
• Adjustments: Your physician can adjust your dosage in case of side effects or change in symptoms.

• Dupixent is a prescription drug. That means that you will need a prescription from your doctor to take it. Your doctor will first examine your condition and medical history to ascertain that it is the right drug for you before he or she prescribes Dupixent.
•  You will need to reveal other drugs that you are taking or have any medical condition to your doctor.
