- Do not use Purified Cortrophin Gel until your healthcare provider has taught you how to give the injection.
Before starting, collect all of the supplies that you will need to use for preparing and injecting Purified Cortrophin Gel. You will need the following supplies:
- Vial of Purified Cortrophin Gel
- Syringe
- Needle for withdrawal (20G or as prescribed by your healthcare provider)
- Needle for injection (23G or as prescribed by your healthcare provider)
- 2 alcohol pads
- Cotton balls or gauze pad
- Bandage (if needed)
- Sharps container for throwing away used syringes and needles (see “Disposing of used needles and syringes”)
Preparing Purified Cortrophin Gel
- Wash your hands well and dry with a clean towel.
- Remove the vial from the refrigerator. Check the expiration date on the vial. Do not use if the expiration date has passed.
Purified Cortrophin Gel will be a solid gel when refrigerated and it needs to be warmed to a liquid gel before injecting. Warm the solid gel in the vial by rolling between your hands for a few minutes. Do not microwave or heat on the stove.

Remove (flip off) the plastic cap from the top of the Purified Cortrophin Gel vial and throw it away in the trash. Do not put the plastic cap back on the vial.

Wipe the top of the vial rubber stopper with a new sterile alcohol pad.

Use a new sterile 20G needle (or needle prescribed for withdrawal) and syringe to draw up the amount of Purified Cortrophin Gel your healthcare provider has told you to use.

Injecting Purified Cortrophin Gel
- Prepare the skin where you are going to give the injection by wiping it with a new sterile alcohol pad. Allow to air dry.
- Replace the 20G needle (or needle prescribed for withdrawal) used for drawing the Purified Cortrophin Gel from the vial with the 23G needle (or needle prescribed for injection). Do not use the 20G needle for injecting.
- Give the injection the way your healthcare provider has instructed you.
- There may be a little bleeding at the injection site. You can press a cotton ball or gauze pad over the injection site (do not rub).
- If needed, you may cover the injection site with a bandage.
- Return the vial to the refrigerator as soon as possible.
Disposing of your used needles and syringe
- Put your used needles and syringe in an FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) your used needles and syringe in your household trash.
If you do not have an FDA-cleared sharps disposal container, you may use a household container that is:
- made of a heavy-duty plastic,
- can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
- upright and stable during use,
- leak-resistant, and
- properly labeled to warn of hazardous waste inside the container.
- When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA’s website at: http://www.fda.gov/safesharpsdisposal.
- Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container.
