Where and how is Kesimpta injected?

Kesimpta (ofatumumab) is injected under the skin (subcutaneously). It should be injected into the stomach area, thigh, or outer upper arm. Kesimpta is available as prefilled syringes and prefilled Sensoready pens.

While Kesimpta may be injected at home, the first injection should be given under the supervision of a healthcare professional. You should also receive training on how to inject Kesimpta safely and properly.

What are the best Kesimpta injection sites?

According to the manufacturer, Kesimpta should be injected under the skin on the lower part of the stomach (except 2 inches around the belly button), front of the thigh, or outer upper arm.

If you are giving the injection to yourself, it is recommended to use the stomach or thigh as the place of injection. If someone else is giving you your Kesimpta injection, they can also inject your dose into the outer upper arm. This site is hard to reach on your own.

Do not inject Kesimpta into areas of skin that are tender, red, or bruised. Also, avoid areas of skin that have moles, stretch marks, or scars.
