Using the PEG-INTRON® REDIPEN® entails these four steps: Mix, Attach, Dial, and Deliver.
Your doctor will prescribe your dose of PEG-INTRON® based on your weight. No other pharmaceutical company manufactures pegylated interferon to be administered based on your weight. (See Is My Weight A Factor With Pegylated Interferon?)
Whether in PEG-INTRON® REDIPEN® or vial and syringe form, PEG-INTRON® is given once a week for 48 weeks. Always follow your doctor's instructions.
You should be completely comfortable with how to prepare the
PEG-INTRON® REDIPEN®, and how to inject yourself before you use
the PEG-INTRON® REDIPEN® for the first time. Your health care
provider will train you in the proper techniques for doing this. Be sure to

Preparing and injecting the PEG-INTRON® REDIPEN® dose:
Using the PEG-INTRON® REDIPEN®, you:
- Mix the medication by pushing down on the pen to combine the PEG-INTRON® powder with sterile water, both stored in the pen. Watch the video.
- Attach the small gauge needle in the PEG-INTRON® REDIPEN®; a self-priming action automatically removes air bubbles from the pen prior to administration. Watch the video.
- Dial to accurately select your predetermined individualized weight-based dose by turning the dosing button until the dosing button aligns with the dosing tab's solid line. Watch the video.
- Deliver the medication by pushing the dosing button completely and holding for five seconds. The five-second period helps ensure that you inject the proper amount of medication. Watch the video.
You will also need to check the injection site 2 hours after the injection for signs of inflammation, such as redness, swelling, or tenderness. If signs of inflammation don't clear up in a few days, notify your health care professional.
Please see the Medication Guide for complete instructions on self-administration.
