Kesimpta (ofatumumab) can cause allergic reactions, although such events are relatively uncommon. Allergic reactions to Kesimpta may range from mild to severe, including symptoms like rash, itching, swelling, and in rare cases, anaphylaxis, which is a serious, potentially life-threatening allergic response.
Kesimpta is a medication used primarily to treat relapsing forms of multiple sclerosis by targeting specific immune cells. Because it modulates the immune system, it can sometimes trigger immune-related side effects, including allergic reactions. These reactions may occur during or shortly after the injection, as Kesimpta is administered subcutaneously (under the skin).
Mild allergic reactions might include redness, swelling, or itching at the injection site, which are relatively common and usually manageable. More systemic allergic symptoms can include hives, difficulty breathing, swelling of the face or throat, and dizziness. Such severe reactions require immediate medical attention.
Patients starting Kesimpta are typically monitored closely during initial doses to detect any allergic responses early. If a patient experiences any signs of an allergic reaction, they should inform their healthcare provider immediately. In some cases, premedication with antihistamines or corticosteroids may be considered to reduce the risk of allergic reactions.
It is important to distinguish allergic reactions from other common side effects of Kesimpta, such as upper respiratory infections or injection site reactions that are not immune-mediated allergies but rather typical drug side effects.
There is no evidence that Kesimpta causes food allergies or intolerances, such as dairy intolerance. Allergic reactions related to Kesimpta are generally related to the drug itself or its administration rather than dietary components.
In summary, while Kesimpta can cause allergic reactions, these are not very common and range from mild local symptoms to rare severe systemic reactions. Patients should be aware of the signs and seek prompt medical care if they suspect an allergy. Healthcare providers take precautions to monitor and manage these risks during treatment.
