How to administer Orencia

Orencia comes in two forms: a subcutaneous injection that you can self-administer at home and an intravenous infusion given by a healthcare provider. The subcutaneous version uses a prefilled syringe or autoinjector pen. Wash your hands, let the medication reach room temperature, inject into the front of the thigh, abdomen, or upper arm, and rotate sites to avoid irritation. After use, dispose of the syringe or pen in a sharps container.

What happens if I miss a dose

If you skip a subcutaneous injection, take it as soon as you remember unless it is almost time for the next scheduled dose. Do not double up. Intravenous infusions require rescheduling through your doctor’s office.

Patients often begin to notice improvement in rheumatoid arthritis symptoms within 2 to 4 weeks, but full benefits may require several months. Clinical studies show steady gains over 6 months.

What side effects are patients asking about

Common complaints include injection-site reactions such as redness, swelling, or pain. Increased risk of serious infections, including tuberculosis and opportunistic infections, is a main concern. Patients also report headaches and nausea. Respiratory infections are frequent.

Why are companies challenging this patent

Generic manufacturers have challenged Orencia’s patents to launch earlier than 2028. The earliest reported challenge occurred in 2014. The challenges focus mainly on the composition-of-matter and method-of-use patents.

When does the patent expire

Orencia’s main patents expire in 2028. DrugPatentWatch.com reports that additional formulation patents may extend protection until 2030 in some cases.
