Tocilizumab Injection

Tocilizumab injection, tocilizumab-bavi injection, and tocilizumab-aazg injection are biologic medications (medications made from living organisms). Biosimilar tocilizumab-bavi injection and tocilizumab-aazg injections are highly similar to tocilizumab injection and work the same way as tocilizumab injection in the body. Therefore, the term tocilizumab injection products will be used to represent these medications in this discussion.

Using tocilizumab injection products may decrease your ability to fight infection from bacteria, viruses, and fungi and increase the risk that you will get a serious or life-threatening infection that may spread through the body. Tell your doctor if you often get any type of infection or if you have or think you may have any type of infection now. This includes minor infections (such as open cuts or sores), infections that come and go (such as cold sores), and ongoing infections that do not go away. Also tell your doctor if you have or have ever had diabetes, human immunodeficiency virus (HIV), low white blood cell counts, or any condition that affects your immune system, and if you live, have ever lived, or traveled to areas such as the Ohio and Mississippi River valleys and the Southwest where severe fungal infections are more common. Ask your doctor if you do not know if these infections are common in your area. Also tell your doctor if you are taking medications that suppress the immune system. Make sure you have discussed any medications you are currently taking or plan to take with your doctor and pharmacist before starting tocilizumab injection products.

Your doctor will monitor you for signs of infection during and after your treatment. If you have any of the following symptoms before you begin your treatment or if you experience any of the following symptoms during or shortly after your treatment, call your doctor immediately: fever; chills; sweating; difficulty breathing; sore throat; cough; weight loss; diarrhea; stomach pain; blood in phlegm; extreme tiredness; muscle aches; warm, red, or painful skin; sores on the skin or in the mouth; burning when you urinate; frequent urination; or other signs of infection.

You may be infected with tuberculosis (TB; a type of lung infection) or hepatitis B (a type of liver disease) but not have any symptoms of the disease. In this case, tocilizumab injection products may increase the risk that your infection will become more serious and you will develop symptoms. Your doctor will perform a skin test to see if you have an inactive TB infection and may order blood tests to see if you have an inactive hepatitis B infection. If necessary, your doctor will give you medication to treat this infection before you start using a tocilizumab injection product. Tell your doctor if you have or have ever had TB or hepatitis B, if you have visited any country where TB is common, or if you have been around someone who has TB. If you have any of the following symptoms of TB, or if you develop any of these symptoms during your treatment, call your doctor immediately: cough, chest pain, coughing up blood or mucus, weakness or tiredness, weight loss, loss of appetite, chills, fever, or night sweats. Also call your doctor immediately if you have any of these symptoms of hepatitis B or if you develop any of these symptoms during or after your treatment: excessive tiredness, yellowing of the skin or eyes, loss of appetite, nausea, vomiting, muscle aches, dark urine, clay-colored bowel movements, fever, chills, stomach pain, or rash.

Keep all appointments with your doctor and the laboratory. Your doctor will monitor your health carefully to be sure you do not develop a serious infection. Your doctor will order certain lab tests before and during your treatment to check your body's response to tocilizumab injection products.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with a tocilizumab injection product and each time you receive the medication. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

Talk to your doctor about the risks of using tocilizumab injection.

Tocilizumab injection products are used alone or with other medications to treat rheumatoid arthritis (a condition in which the body attacks its own joints, causing pain, swelling, and loss of function) in adults who have not been helped by other disease-modifying antirheumatic drugs (DMARDs). Tocilizumab injection products are also used in children 2 years of age or older alone or in combination with methotrexate (Otrexup, Rasuvo, Xatmep, others) to treat polyarticular juvenile idiopathic arthritis (PJIA; a type of childhood arthritis that affects five or more joints during the first six months of the condition, causing pain, swelling, and loss of function) and systemic juvenile idiopathic arthritis (SJIA; a condition in children that causes inflammation in different areas of the body, causing fever, joint pain and swelling, loss of function, and delays in growth and development). Tocilizumab injection products (Actemra, Tyenne) are used to treat giant cell arteritis (a condition that causes swelling of blood vessels, especially in the scalp and head) in adults. Tocilizumab injection (Actemra) is used to treat systemic sclerosis-associated interstitial lung disease (SSc-ILD; also known as scleroderma-associated ILD: a lung disease that involves scarring of the lungs) in adults. Tocilizumab injection (Actemra) is also used alone or in combination with corticosteroids to treat cytokine release syndrome (a severe and possibly life-threatening reaction) in adults and children 2 years of age or older. Tocilizumab injection (Actemra) is also used in combination with corticosteroids to treat coronavirus disease 2019 (COVID-19 infection) caused by the SARS-CoV-2 virus in hospitalized adults who require supplemental oxygen, a ventilator, or who need extracorporeal membrane oxygenation (ECMO; a device that adds oxygen to the blood). Tocilizumab injection products are in a class of medications called interleukin-6 (IL-6) receptor inhibitors. They work by blocking the activity of interleukin-6, a substance in the body that causes inflammation.

Tocilizumab injection products (Actemra, Tofidence, Tyenne) come as a solution (liquid) to be injected intravenously (into a vein) about over 1 hour by a doctor or nurse in a medical office or hospital outpatient clinic. Tocilizumab injection products (Actemra, Tyenne) also come as a solution (liquid) in a single-dose prefilled syringe and an automatic injection device to inject subcutaneously (just under the skin) by yourself at home. When tocilizumab injection products are given to treat rheumatoid arthritis, giant cell arteritis, polyarticular juvenile idiopathic arthritis, or systemic juvenile idiopathic arthritis, they may be injected intravenously once every 2 or 4 weeks or may be injected subcutaneously (Actemra, Tyenne) once every week or every 2 or 3 weeks. When tocilizumab injection products are given to treat systemic sclerosis-associated interstitial lung disease, they are usually given subcutaneously (Actemra) once weekly. When tocilizumab injection products are given to treat cytokine release syndrome, they are usually given intravenously (Actemra) as one dose, but up to 3 additional doses may be given at least 8 hours apart. When tocilizumab injection products (Actemra) are given to treat coronavirus disease 2019 (COVID-19 infection), they are usually given intravenously as one dose, but an additional dose may be given at least 8 hours after the initial dose.

You will receive your first subcutaneous dose of tocilizumab injection products in your doctor's office. If you will be injecting tocilizumab injection products subcutaneously by yourself at home or having a friend or relative inject the medication for you, your doctor will show you or the person who will be injecting the medication how to inject it. You and the person who will be injecting the medication should also read the written instructions for use that come with the medication. Be sure to ask your doctor or pharmacist if you have any questions about how to inject the medication.

If you are using a prefilled syringe or an automatic injection device that has been refrigerated, place the syringe or device on a flat surface and allow it to reach room temperature (30 minutes for the prefilled syringe and 45 minutes for the automatic injection device) before you are ready to inject the medication. Do not try to warm the medication by heating it in a microwave, placing it in warm water, or through any other method. Do not remove the cap from the prefilled syringe or automatic injection device while the medication is warming. You should remove the cap right before you inject the medication. Do not use the syringe or device if you drop it on the floor.

Before you use tocilizumab injection products, look at the solution in the prefilled syringe or automatic injection device closely. Check that the expiration date has not passed. The medication should be clear and colorless to pale yellow and should not be cloudy or discolored or contain lumps or particles. Call your pharmacist if there are any problems with the package or the syringe and do not inject the medication.

You may inject tocilizumab injection products on the front of the thighs or anywhere on your stomach except your navel (belly button) and the area 2 inches around it. If another person is injecting your medication, the outer area of the upper arms also may be used. Do not inject the medication into skin that is tender, bruised, red, hard, or not intact, or that has scars, moles, or bruises. Choose a different spot each time you inject the medication, at least 1 inch away from a spot that you have used before. If the full dose is not injected, call your doctor or pharmacist.

Use each prefilled syringe or automatic injection device once and inject all the solution in the syringe or automatic injection device. Do not reuse tocilizumab prefilled syringes or automatic injection devices and do not recap the syringes or device after use. Discard any used syringes in a puncture-resistant container and ask your pharmacist how to throw away the container.

Tocilizumab injection may help control your symptoms, but it will not cure your condition. Your doctor will watch you carefully to see how well tocilizumab injection works for you. Your doctor may adjust your dose or delay your treatment if you have certain changes in your laboratory results. It is important to tell your doctor how you are feeling during your treatment.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
