• The Dupixent Pre-filled Syringe is simple to use and is designed for self-administration. The below is a step-by-step guide on how to use the syringe properly:

Preparation:

• Remove the syringe from the refrigerator at least 30 minutes before use to allow it to come to room temperature.
• Wash your hands with soap and water.
• Have a flat, clean area to give the injection.

Injection Site:

• The injection should be given subcutaneously (under the skin). The thigh or abdomen are good places. Never use bruised or scar tissue.
• Do not inject close to your waistline, belly button, or other sensitive areas.

Injecting

• Take off the protective cap from the syringe and inspect for any visible particles or color change. It should be clear to light yellow.
• Pinch the skin at the injection site gently to lift it away from the underlying tissue.
• Insert the needle at a 90-degree angle to your skin and slowly push the plunger to inject the medicine.
• After giving the medicine by injection, remove the needle from the skin.
• After Injection:
• Dispose of the syringe properly in a sharps container. Do not reuse the syringe.
• Wash your hands once more after throwing away the syringe.
• Missed Dose: The dose should be taken by a patient if one remembers. If it is near time to take the next dose, ignore the missed dose and resume a regular dosing schedule. Two doses at once should be taken.

Dupixent Pre-filled Syringe works by blocking two specific proteins of the immune system — IL-4 and IL-13. They are responsible for triggering inflammation in eczema, asthma, and nasal polyps. By blocking the function of these proteins, Dupixent alleviates the inflammation responsible for causing symptoms of these diseases.

• IL-4 and IL-13: These two proteins have been said to be behind allergic reactions and chronic inflammation. By reducing their activity, Dupixent manages and stabilizes the inflammation at its root, preventing flare-ups and reducing the severity of symptoms.
• Dupilumab: Dupilumab, the active substance in Dupixent, is specifically engineered to target IL-4 and IL-13, offering a targeted way of managing inflammation in eczema and asthma conditions, thus making it easier for the patient to manage their chronic condition.
• The Dupixent Pre-filled Syringe ensures that patients inject the proper, consistent dose with each injection.

• As with all medications, Dupixent Pre-filled Syringe has side effects, but not everyone experiences them. Some side effects are expected, and some are dangerous.
• Common Side Effects
• Injection site reactions: Pain, swelling, or redness at the injection site.
• Eye problems: Dry eyes, eye irritation, or conjunctivitis (pink eye).
• Cold-like symptoms: Cough, congestion, runny nose, or sore throat.
• Dangerous Side Effects:
• Allergic reactions: While rare, some people can have severe allergic reactions like swelling of the face, lips, or throat or shortness of breath. In this situation, call emergency medical help.
• Infections: Dupixent has a weak effect on the immune system, causing infections. If you have symptoms of infection, i.e., fever, chills, or a persistent cough, call your doctor.

• Before using Dupixent, tell your doctor about your allergies or medical conditions. The precautions required are as follows:
• Eye problems: Dupixent may lead to eye problems such as eye inflammation or conjunctivitis. If you experience eye pain or any change in your vision, report it to your health care provider.
• Pregnancy and Lactation: Discuss with your physician if you are pregnant, become pregnant, or are breastfeeding. Dupixent is to be used during pregnancy only if the benefits to the fetus outweigh the risk to the fetus.
• Infections: If you have had infections or are at risk for infections, discuss with your physician. Dupixent may increase the risk of infection.
• Allergies: Be sure to inform your doctor if you are allergic to dupilumab or to any ingredients in Dupixent.

• Other Drugs: Dupixent can be administered together with other medications like inhaled corticosteroids for asthma or topical treatment for eczema. Be sure to inform your doctor what other drugs you are on in order to avoid potential interactions.
• Vaccines: If a vaccine is to be taken while taking Dupixent, live vaccines can be avoided since they will interact with Dupixent’s impact on the immune system. Your doctor needs to be consulted before taking vaccines

• Your first dose is based on the condition for which you are receiving treatment. What you take subsequently is normally 300 mg every two weeks, but your doctor may adjust this according to your needs and the way you react.
• Regular use: You should follow your dosing schedule with your doctor and not skip doses in order to manage your symptoms appropriately.
• If you are having side effects or feel like nothing is happening after a few weeks, your physician can recommend altering the dosage.

• Dupixent is a medication that you have to get with a physician’s prescription, so you will need to get a prescription from your doctor before you can utilize it. Your doctor will study your condition, consider your history, and determine whether Dupixent would be a good fit for you prior to your using Dupixent.
• Before you administer the Dupixent Pre-filled Syringe to yourself, ensure that you are adequately trained on administering it to yourself. Blind obedience to your physician’s instructions is also extremely important for the best results.
