Orencia is made by Bristol-Myers Squibb.
Rheumatoid arthritis is thought to be caused by an overactive immune system that attacks the body's own healthy tissues. Many
rheumatoid arthritis treatments work by suppressing the immune system, preventing the body from attacking itself.
Orencia works by inhibiting T cells. T cells are a type of white blood cell (leukocytes) that play an important role in the immune system. Orencia seems to prevent T cells from being active and multiplying too much.
Orencia has been evaluated for rheumatoid arthritis in several different studies. In these studies, the drug Orencia was given to people who had unsuccessfully tried various other rheumatoid
arthritis medications. In these studies, people who took Orencia had fewer tender or swollen joints and were better able to perform their usual daily activities (such as walking, eating, or dressing), compared to people who did not take Orencia. The medication also slowed the structural damage to the joints.
Because Orencia targets a specific part of the immune system, it is called a "biological response modifier" because it changes (modifies) the body's immune response. It is also known as a "biologic" medication because it is made out of parts of cells or proteins.
When and How to Take Orencia
General considerations for when and how to take Orencia include the following:
- Orencia is taken by IV. The first three Orencia doses are given every two weeks; after that, they are given once every four weeks.
- You will probably receive your Orencia IV at your healthcare provider's office or at an infusion center. The IV takes about 30 minutes, but the entire process usually lasts awhile longer, due to paperwork, waiting, and preparation for the IV.
- For the medication to work properly, it must be taken as prescribed. Orencia will not work if you stop taking it.
Orencia Dosing Information
The dose of Orencia that your healthcare provider recommends will vary depending on a number of factors, including:
- Your weight
- Other medications you may be taking
- Other medical conditions you may have.
As is always the case, do not adjust your Orencia dose unless your healthcare provider specifically instructs you to do so.
As with any medicine, side effects are possible with Orencia. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
Common side effects of Orencia include, but are not limited to:

What If I Take an Overdose of Orencia?
An Orencia overdose is unlikely, since the drug is given through IV by your healthcare provider. In studies, doses of about five times the recommended
Orencia dosage did not cause any problems (other than the usual side effects of Orencia).
What Should I Do If I Miss a Dose of Orencia?
If you do not receive an Orencia dose as scheduled, call your healthcare provider to set up an appointment to receive your dose as soon as possible.
