Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:


Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of tocilizumab injection in children with PJIA, SJIA, and CRS. However, safety and efficacy have not been established for other conditions and in children younger than 2 years of age.


Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of tocilizumab injection in the elderly. However, elderly patients are more likely to have serious infections, which may require caution in patients receiving tocilizumab injection.

It may sometimes be given at home to patients who do not need to be in the hospital or clinic. If you are using this medicine at home, your doctor or nurse will teach you how to inject the medicine. Be sure that you understand exactly how to use this.

This medicine comes with a Medication Guide and patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

This medicine is available in 2 forms. You may use a prefilled syringe or an autoinjector.

If you use this medicine at home, you will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems. Do not inject into scars, moles, or skin areas that are red, bruised, tender, hard, or not intact.

Allow the prefilled syringe to warm to room temperature 30 minutes or the autoinjector for 45 minutes before using it. Do not warm it in any other way.

It is very important that your doctor check your or your child's progress at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.

You or your child will need to have a skin test for tuberculosis before you start using this medicine. Tell your doctor if you or anyone in your home has ever had a positive reaction to a tuberculosis skin test.

This medicine will lower the number of some types of blood cells in your body. Because of this, you may bleed or get infections more easily. To help with these problems, avoid being near people who are sick or have infections. Wash your hands often. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Brush and floss your teeth gently. Be careful when using sharp objects, including razors and fingernail clippers. Tell your doctor if you have any kind of infection before you start using this medicine. Also tell your doctor if you have ever had an infection that would not go away or an infection that keeps coming back.

Call your doctor right away if you or your child start to have a cough that would not go away, weight loss, night sweats, fever, chills, or flu-like symptoms, such as a runny or stuffy nose, headache, blurred vision, or feeling generally ill. These may be signs that you have an infection.

This medicine may cause serious stomach and bowel problems, especially if you have a history of ulcers or diverticulosis. Check with your doctor right away if you or your child start having severe stomach cramps or pain, black, tarry stools, diarrhea, fever, or vomiting that is severe and sometimes bloody while being treated with this medicine.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

While you or your child are being treated with tocilizumab, and after you stop treatment with it, it is important to see your doctor about the immunizations (vaccinations) you should receive. Do not get any immunizations (vaccines) without your doctor's approval. Tocilizumab may lower your body's resistance, and there is a chance you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live virus vaccines because there is a chance that they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.
