Tocilizumab treats certain types of arthritis and inflammation of the lining of the arteries. Can increase your risk for serious infections. Report signs of infections such as fever to your doctor.
Tocilizumab is a prescription medication used to treat rheumatoid arthritis (RA) in adults. It is used to treat systemic juvenile idiopathic arthritis (SJIA) or polyarticular juvenile idiopathic arthritis (PJIA) in children 2 years or older. This medication is also used to treat giant cell arteritis, inflammation of the lining of the arteries.
Tocilizumab is referred to as an interleukin-6, or IL-6, receptor inhibitor. IL-6 is a molecule produced by the body that binds to the IL-6 receptor and causes inflammation. Patients with arthritis have increased levels of IL-6 in their body. By blocking the IL-6 receptor, tocilizumab can decrease the symptoms of arthritis.
Tocilizumab comes in an injectable form to be given directly into a vein (IV) or under the skin by a healthcare provider, depending on the condition being treated.
It is usually given once every 4 weeks for RA and PJIA, every 2 weeks for SJIA and once every week for giant cell arteritis.
Common side effects of tocilizumab are cold-like symptoms, increased blood pressure, and headache.

This is not a complete list of tocilizumab drug interactions. Ask your doctor or pharmacist for more information.
Tocilizumab can cause serious infections by lowering the ability of your immune system to fight infections including tuberculosis (TB), as well as others. These are serious infections that may cause death.
- Your doctor should test you for TB before starting tocilizumab as well as monitor you closely for signs and symptoms of TB during treatment with tocilizumab.
- fever, sweating, or chills
- warm, red, or painful skin or sores
- muscle aches on your body
- diarrhea or stomach pain
- shortness of breath
- burning when you urinate or urinating more often than normal
- blood in phlegm
- weight loss
- feel very tired
Before starting tocilizumab, tell your doctor if you:
- are being treated for an infection
- get a lot of infections or have infections that keep coming back
- have diabetes, HIV, or a weak immune system. People with these conditions have a higher chance of infections.
- have TB, or have been in close contact with someone with TB
- live or have lived, or have traveled to certain parts of the country (such as the Ohio and Mississippi River valleys and the Southwest) where there is an increased chance of getting certain kinds of fungal infections (histoplasmosis, coccidiomycosis, or blastomycosis). These infections may happen or become more severe if you use tocilizumab. Ask your doctor, if you do not know if you have lived in an area where these infections are common.
- have or have had hepatitis B.
- Before taking tocilizumab, tell your doctor if you have had diverticulitis (inflammation in parts of the large intestine) or ulcers in your stomach or intestines. Some people taking tocilizumab get tears in their stomach or intestine. This happens most often in people who also take nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate.
- Tell your doctor right away if you have a fever and stomach-area pain that does not go away, and a change in your bowel habits.
- low neutrophil count. Neutrophils are white blood cells that help the body fight off bacterial infections.
- low platelet count. Platelets are blood cells that help with blood clotting and stop bleeding.
- increase in certain liver function tests.
You should not receive tocilizumab if your neutrophil or platelet counts are too low or your liver function tests are too high. Your doctor may stop your tocilizumab treatment for a period of time or change your dose of medicine if needed because of changes in these blood test results.
Tocilizumab Food Interactions
Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of tocilizumab, there are no specific foods that you must exclude from your diet when receiving tocilizumab.

Tocilizumab and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
This medication falls into category C. It is not known if tocilizumab will harm your unborn baby.
Tocilizumab and Lactation
Tell your doctor if you plan to breastfeed or are breastfeeding.
It is not known if tocilizumab is excreted in human breast milk. You and your doctor should decide if you will take tocilizumab or breastfeed. You should not do both.
You will receive tocilizumab from a healthcare provider through a needle placed in a vein in your arm (IV or intravenous infusion). The infusion will take about 1 hour to give you the full dose of medicine.
This medication is also injected under the skin for giant cell arteritis.
- For rheumatoid arthritis, you will receive a dose of tocilizumab about every 4 weeks.
- For SJIA you will receive a dose of tocilizumab about every 2 weeks.
- For giant cell arteritis, you will receive a dose once every week. This medication is given together with a tapering course of glucocorticoids.
- If you miss a scheduled dose of tocilizumab, ask your healthcare provider when to schedule your next infusion.
- While taking tocilizumab, you may continue to use other medicines that help treat your rheumatoid arthritis or SJIA such as methotrexate, non-steroidal anti-inflammatory drugs (NSAIDs) and prescription steroids, as instructed by your healthcare provider.
- Keep alI of your follow-up appointments and get your blood tests as ordered by your healthcare provider.
Your doctor will determine your tocilizumab dose based on your weight. The recommended dose of tocilizumab is 4-8 mg/kg administered as a single 60 minute intravenous (into a vein) infusion every 4 weeks for treating RA or PJIA.
For SJIA you will receive a dose of tocilizumab about every 2 weeks.
For giant cell arteritis, you will receive a dose of tocilizumab (162mg) once every week. In some cases, some will receive tocilizumab once every other week.
Tocilizumab is usually administered by a healthcare provider in a medical setting making it unlikely for an overdose to occur. However, if an overdose is suspected, seek emergency medical attention.
It is important you keep all of your medical and laboratory appointments while receiving tocilizumab. Call your doctor for instructions if you miss an appointment for your tocilizumab injection.
Tocilizumab FDA Warning
WARNING: RISK OF SERIOUS INFECTIONS
Patients treated with tocilizumab are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.
If a serious infection develops, interrupt tocilizumab until the infection is controlled.
Reported infections include:
- Active tuberculosis, which may present with pulmonary or extrapulmonary disease. Patients should be tested for latent tuberculosis before tocilizumab use and during therapy. Treatment for latent infection should be initiated prior to tocilizumab use.
- Invasive fungal infections, including candidiasis, aspergillosis, and pneumocystis. Patients with invasive fungal infections may present with disseminated, rather than localized, disease.
- Bacterial, viral and other infections due to opportunistic pathogens.
The risks and benefits of treatment with tocilizumab should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection.
Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with tocilizumab, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy.
