How do you inject Kesimpta (ofatumumab) step by step?
Kesimpta is injected under the skin (subcutaneous), using a prefilled pen or prefilled syringe (depending on your prescription). The general process is: choose the injection site, prepare the medication and supplies, clean the skin, inject, and dispose of the sharps.
Common subcutaneous injection sites are the abdomen (at least 5 cm away from the navel), the front of the thigh, and the back of the upper arm (only if someone else can inject for you). Rotate sites to reduce irritation.
Follow the exact technique and schedule in your Kesimpta Medication Guide or the instructions your nurse/pharmacist gave you, because the first doses follow a specific weekly pattern and the device technique can differ slightly by pen vs syringe.
What injection sites can you use, and where should you avoid?
You can typically inject into:
- Abdomen (not directly around the navel)
- Thigh
- Outer upper arm (if another person does the injection)
Avoid injecting into skin that is:
- Red, bruised, tender, hard, or scarred
- Infections or areas with rashes
What should you do before injecting (preparation checklist)?
Before you inject, confirm:
- Your pen/syringe is the correct strength and not expired
- The solution looks as expected for your product (follow the Medication Guide on what “acceptable” looks like)
- You have alcohol wipes and a sharps disposal container
- You can follow the injection timing instructions exactly (especially for the first month schedule)
Let the medication come to room temperature if your Medication Guide instructs it. Don’t warm it using heat sources.
How is the dose given if you’re using the prefilled pen vs the prefilled syringe?
The main difference is the delivery mechanism:
- With a prefilled pen, you generally press/activate the device per the on-device instructions until the injection completes.
- With a prefilled syringe, you insert the needle and deliver the medication using the syringe plunger per the Medication Guide.
If you tell me whether you have the pen or the syringe, I can describe the injection flow more specifically to that device type.
What if you miss a dose or take it late?
Missed-dose instructions depend on where you are in the dosing schedule. Because Kesimpta has an initial dosing regimen (more frequent early dosing) and then later maintenance dosing, the correct action can differ based on how far you are from the scheduled day. Use the “missed dose” guidance in your Kesimpta Medication Guide or call your prescribing clinician/pharmacy for instructions tailored to your timeline.
How do you dispose of used needles and pens safely?
Put the used pen/syringe into an FDA-cleared sharps container right away. Don’t recap needles unless your device instructions specifically require it (many disposable injections do not). When the container is full, follow local rules for disposal or return programs.
When should you call a clinician after injecting?
Contact your healthcare team promptly if you have signs of a serious reaction or severe infection symptoms. Also ask your clinician if you get persistent injection-site reactions.
If you share:
1) whether you’re using the pen or syringe,
2) which week/month of therapy you’re on, and
3) where you plan to inject,
I can tailor the instructions and help you match the technique to your current schedule.
