How to Use This Medication

Read the Medication Guide and, if available, the Instructions for Use Leaflet provided by your pharmacist before you start using peginterferon and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

If you are using this medication at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

If this medication is stored in the refrigerator, remove the medication from the refrigerator and let it warm at room temperature for about 30 minutes before injecting. Do not use heat sources (such as warm water) to warm this medication.

Before injecting each dose, clean the injection site with rubbing alcohol. Change the injection site each time to lessen injury under the skin. Do not inject into skin that is irritated, bruised, scarred, or infected. Inject this medication under the skin in the thigh, abdomen, or the back of the upper arm as directed by your doctor, usually every 14 days. Check the injection site 2 hours after injecting to see if there is any reaction at the injection site. Tell the doctor of any skin reactions that do not go away after a few days.

To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. A starter pack with different doses of this medication may be used when starting this medication. Follow your doctor's instructions carefully.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time and same day of the week.

You may need to take other medications to reduce common side effects such as fever and pain (such as acetaminophen, ibuprofen). Consult your doctor or pharmacist about how to use these medications safely with peginterferon.

Tell your doctor if your condition worsens.
