How is certolizumab given (Cimzia)?

Before you start treatment with certolizumab, your doctor may perform tests to make sure you do not have tuberculosis or other infections.

Some infections are more likely to occur in certain areas of the world. Tell your doctor where you live and where you have recently traveled or plan to travel to during treatment.

Certolizumab is given as two injections under the skin of your stomach or thigh.

This medication is usually given every 2 to 4 weeks.

Certolizumab can lower blood cells that help your body fight infections. Your blood may need to be tested often. Avoid being near people who are sick or have infections. Avoid activities that may increase your risk of bleeding injury. Serious and sometimes fatal infections may occur during treatment with certolizumab. Contact your doctor right away if you have signs of infection such as: fever, cough, sweating, tired feeling, or if you feel short of breath.

Use certolizumab regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.

If you need surgery, tell the surgeon ahead of time that you are using certolizumab.

This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using certolizumab.
