certolizumab pegol (ser toe LIZ oo mab)(pe GOL)
What is certolizumab pegol?
Cimzia injection contains the active ingredient certolizumab, which is a type of medicine called a human monoclonal antibody.It works by suppressing part of the immune system and modifying the process of inflammation. Certolizumab works in a similar way to the natural antibodies produced by our immune system. Our natural antibodies recognize foreign invaders and bind to them, helping our immune systems to attack them and protect us from infections. Monoclonal antibodies like certolizumab are made in laboratories and are designed to recognize particular proteins in a similar way.
Certolizumab specifically recognizes and binds to a protein produced by the body called tumor necrosis factor alpha (TNF alpha). TNF alpha is involved in producing inflammation and can be found in the inflamed lining of the intestine of people with Crohn’s disease.
By binding to TNF alpha, certolizumab prevents the inflammatory responses it causes. By reducing inflammation, it reduces related symptoms.
Cimzia is similar to Humira except that is contains a special chemical called polyethylene glycol (PEG), which delays its excretions from the body. For this reason, Cimzia can be given less frequently than Humira.
What is it used for?
It is used to treat moderate to severe forms of rheumatoid arthritis and cases of severe active Crohn’s disease.
How do I take it?
Cimzia is administered as an injection subcutaneously (under the skin) every four weeks after an initial series of three injections given every two weeks. It is usually given as an injection at your doctor’s office, hospital or clinic. If you will be using Cimzia at home, a healthcare provider will teach you how to use it. Be sure you understand how to use Cimzia. Follow the procedures you are taught when you use a dose. Contact your healthcare provider if you have any questions. Do not use Cimzia if it contains particle, is cloudy or discolored, or if the vial is cracked or damaged. Do not shake Cimzia. Rotate injection sites. New injections should be given at least 1 inch from an old site. Do not inject into areas of the skin that are sore, bruised, red or hard. Keep this product, as well as syringes and needles, out of the reach of children and pets. Do not reuse needles, syringes or other materials.

The most significant drug interaction can occur with anakinra (Kineret); this combination may increase the risk of serious infections.
Is there a problem if I have another disorder or disease?
At times, a drug may have a different or enhanced effect when other diseases are present. At other times, the drug may worsen or affect another disease. This drug should be used with caution for patients with decreased kidney function, decreased liver function, history of heptitis B, dormant (currently inactive) tuberculosis infection, history of recurrent infections, history of past/current cancer, mild heart failure, multiple sclerosis, heavy smokers and latex allergies. People receiving long-term oral corticosteroids, chemotherapy, radiotherapy or medicine to prevent transplant rejection are at high risk when taking this medicine. Please consult a physician beforehand.
What about allergies?
People who have known allergies or asthma may be at an increased risk for a reaction from any new medication. The physician should always know a patient’s allergy history. Signs of an allergic reaction are rash, hives or fever. Of course, a person should not take certolizumab if there has been a previous reaction to this medicine. Also, patients with latex allergies should not use Cimzia, as the needle cover of the syringe contains latex.
What if I’m pregnant, considering pregnancy or breast-feeding?

A physician’s comment…
The effects of Cimzia appear to be comparable to other anti-TNF agents like Humira and Remicade, though no comparative studies have yet been completed. The most notable advantage to Cimzia is its less frequent administration. Doctors prescribe Cimzia to patients with moderate to severe Crohn’s disease who had an inadequate response to conventional therapies.
