Biologics and biosimilars are given by subcutaneous injection (injected into fat tissue under the skin) or intravenous infusion (injected directly into a vein) because the proteins can be damaged by stomach acid if given by mouth. Infusions will require administration by a healthcare professional while self-injection can be performed by patient or caregiver at home.
The injection may be given daily, weekly, every few weeks or every year. Your doctor will discuss with you which biologic or biosimilar is right (most effective and safest) for you, how to administer and how often to be given.
