As with any medication, there is the potential for mild or more severe allergic reactions, which are uncommon.
Overview
Monoclonal antibodies (also called moAbs or mAbs) are proteins made in laboratories that act like proteins called antibodies in our bodies. Antibodies are parts of your immune system. They seek out the antigens (foreign materials) and stick to them in order to destroy them.
Procedure Details
In most cases, monoclonal antibodies are given mostly as intravenous (IV) solution injected right into your vein (sometimes referred to as an infusion). They’re often given in an infusion center where there are several people getting treatment at one time.
