Drug information provided by: Merative, Micromedex®

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.

Using this medicine may increase your risk of having certain cancers. Talk to your doctor if you have unusual bleeding, bruising, or weakness, swollen lymph nodes in the neck, underarms, or groin, or unexplained weight loss. Also, check with your doctor right away if your skin has red, scaly patches, or raised bumps that are filled with pus.

Tocilizumab may cause headaches and skin reactions, such as a rash or itching, while you are receiving the injection or within 24 hours after you receive it. Check with your doctor or nurse right away if you or your child have any of these symptoms.

This medicine may cause serious types of allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Tell your doctor right away if you or your child have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after using this medicine.

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.

This medicine may increase the amounts of cholesterol and fats in your blood. If this condition occurs, your doctor may give you some medicines that can lower their amounts. Talk to your doctor if you or your child have concerns.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
