Dupixent Pen Vs Syringe: Which is easy to inject, less painful, and less costly? Here is a comparison of Dupixent prefilled pen devices vs Dupixent prefilled syringes.

Dupixent (Dupilumab): a breakthrough in biologic medicine …

Dupixent is a biological medicine that targets Interleukin 4 Receptor Alpha (IL-4Rα). It inhibits the processes that are executed by IL-4 and IL-13 since both these interleukins bind to IL4Rα.

It is used to treat the following conditions:

  • Atopic Dermatitis (Eczema)
  • Allergic or eosinophilic asthma
  • Chronic Rhinosinusitis with nasal polyps, and
  • Eosinophilic esophagitis.

It has been associated with paradoxical facial redness and eye problems, the cause of which is not very clear.

Dupixent is available as a pre-filled pen device as well as a pre-filled syringe. Whether you choose a pen-filled Dupixent device or a syringe, it’s up to you.

However, there are some minor differences between the two.

Dupixent Pen Vs Syringe:

Dupixent prefilled syringes can be used by children and adults while the prefilled pen is not recommended for use in younger children aged 12 years or younger.

A Dupixent syringe is available in doses of 100 mg, 200 mg, and 300 mg injections while a Dupixent pen is available in doses of 200 mg and 300 mg only.

Dupixent prefilled pen is kept at 90 degrees when injecting it. A Dupixent syringe is administered at 45 degrees.

Dosage strengths Available as 200 mg and 300 mg prefilled pen Available as 100 mg, 200 mg, and 300 mg syringes
Angle of injection 90 degrees 45 degrees

The needle is visible in the syringe when injecting Dupixent while in the pre-filled pen device, the needle is covered by a needle cover.

People who have needle phobia should choose Dupixent pens rather than Dupixent syringes.

When injecting Dupliumab via Dupixent pen, you won’t see the needle going in. Once the pen is pushed against the skin, the needle cover goes up and the needle enters the skin.

Which is painful: Dupixent Pen Vs Syringe?

Different patients have different reviews. Most patients who are scared of needles don’t like prefilled syringes. For some patients, it was not the prick that hurt but the medicine.

If you are not scared of the needle and it’s the medicine that hurts when it is being injected, then the syringe is probably the best option.

Because you can control the speed of the injection when using a syringe, you can control the pain too. A slow injection may hurt less and you can inject it as slowly as over one minute or more.

Secondly, when using the Dupixent syringe, you can also control the angle at which to inject. For very skinny people, it may be best to inject at an angle of 45 degrees.

You can do that with the syringe but not when using the Dupixent prefilled pen.
