What Kind of Medicine Is Ofatumumab?
Simply put, Ofatumumab is a prescription medicine used to treat Multiple Sclerosis. You might also hear it called by its common brand name, Kesimpta. It belongs to a group of medicines designed to calm your body's internal defenses.
In MS, your immune system mistakenly attacks your own nerves and spinal cord. This attack causes the uncomfortable symptoms you experience. Ofatumumab steps in to quiet down your overactive immune system. This calming effect helps stop new attacks and keeps your symptoms manageable over time.
Ofatumumab does not cure MS completely. However, it helps you manage the condition, reduce flare-ups, and live a more comfortable daily life.

You take Ofatumumab as an injection under your skin, known as a subcutaneous injection. At first, giving yourself an injection might feel a bit scary. Your doctor or a trained nurse will teach you step-by-step how to do it safely at home.

Always throw away used needles and syringes in a special hard plastic container called a sharps container. Never put loose needles into your regular household trash. If you do not have a sharps container, ask your doctor where to get one to keep your family safe.
