WARNING

Tocilizumab is a medication used to treat various conditions like rheumatoid arthritis and cytokine release syndrome. While it’s generally effective, it comes with potential risks:

• Infections: Tocilizumab can increase the risk of serious infections, including tuberculosis and other bacterial, viral, or fungal infections.
• Liver Issues: It can affect liver function, leading to elevated liver enzymes and potentially serious liver problems.
• Blood Count Changes: It may cause changes in blood cell counts, such as low white blood cells (leukopenia) or low red blood cells (anemia).
• Gastrointestinal Problems: Some people may experience gastrointestinal issues, such as nausea or abdominal pain.
• Elevated Cholesterol: Tocilizumab can increase cholesterol levels, which might need monitoring.

It’s important to discuss these risks with a healthcare provider to weigh the benefits and manage any potential side effects.

Why is this medication prescribed?

Tocilizumab is a medication that is primarily used to treat certain conditions involving inflammation and overactive immune responses. It is commonly prescribed for:

• Rheumatoid Arthritis: Tocilizumab helps reduce the symptoms and progression of rheumatoid arthritis, a condition where the immune system attacks the joints.
• Systemic Juvenile Idiopathic Arthritis (SJIA): It’s used in children with SJIA to help manage the condition and reduce inflammation.
• Giant Cell Arteritis (GCA): Tocilizumab can be used to treat GCA, an inflammation of the blood vessels that can lead to serious complications if untreated.
• Cytokine Release Syndrome (CRS): In certain cancer treatments, like CAR-T cell therapy, Tocilizumab is used to manage CRS, a serious side effect where the immune system releases too many inflammatory cytokines.

The drug works by inhibiting interleukin-6 (IL-6), a cytokine involved in inflammation. By blocking IL-6, Tocilizumab helps reduce inflammation and alleviate symptoms related to these conditions.

How should this medicine be used?

Tocilizumab is administered as an injection, and its use depends on the specific condition being treated. Here are general guidelines for its administration:

• Route: Tocilizumab can be given intravenously (IV) or subcutaneously (under the skin). The method of administration depends on the condition and the specific formulation used.
• Intravenous Administration:
  • Dosage: The dosage and frequency are determined based on the condition being treated. For rheumatoid arthritis, it’s typically given as an IV infusion every 4 weeks.
  • Procedure: The infusion is administered slowly over a period of time, often about 1 hour. It is usually done in a healthcare setting.
• Subcutaneous Administration:
  • Dosage: For certain conditions like rheumatoid arthritis, it might be administered as a self-injection under the skin. This is usually done every 1 or 2 weeks, depending on the specific dosage regimen prescribed.
  • Procedure: Patients are often trained by their healthcare provider on how to administer the injection properly at home.
• Preparation: If you’re administering it yourself, follow all instructions provided by your healthcare provider or the medication guide carefully. This includes proper preparation of the injection site and the medication itself.
• Monitoring: Regular follow-ups with your healthcare provider are important to monitor for side effects and to adjust the dosage if needed.

Always follow your healthcare provider’s instructions and guidelines regarding the use of Tocilizumab. If you have any questions or concerns about the medication, including how to administer it or what to expect, your healthcare provider or pharmacist can provide detailed guidance.

Other uses for this medicine

• COVID-19: It has been used to treat severe cases of COVID-19 in hospitalized patients with high levels of inflammation, especially those with severe respiratory symptoms.
• Castleman’s Disease: Tocilizumab is sometimes used for this rare condition involving excessive growth of lymph nodes and other tissues.

What special precautions should I follow?

When using Tocilizumab, several precautions should be taken:

• Infections: Since Tocilizumab suppresses the immune system, it can increase the risk of infections. Be cautious and inform your healthcare provider if you have any signs of infection, such as fever or chills.
• Liver Function: Regular liver function tests may be required, as Tocilizumab can affect liver enzymes. Report any symptoms of liver problems, such as jaundice or dark urine.
• Cholesterol Levels: Tocilizumab may increase cholesterol levels, so monitoring and managing cholesterol is important.
• Blood Cell Counts: Regular blood tests may be necessary to monitor white blood cell counts, red blood cell counts, and platelet levels, as Tocilizumab can affect these.
• Vaccinations: Live vaccines should generally be avoided while on Tocilizumab. Consult your healthcare provider about any vaccinations you need.
• Allergies: Inform your healthcare provider if you have any known allergies, particularly to medications or components of Tocilizumab.
• Pregnancy and Breastfeeding: Discuss with your healthcare provider if you are pregnant, planning to become pregnant, or breastfeeding, as Tocilizumab may have effects on pregnancy and lactation.
• Other Medications: Be sure to inform your healthcare provider about all other medications and supplements you are taking, as they may interact with Tocilizumab.

Following these precautions and maintaining open communication with your healthcare provider can help manage risks and ensure the safe use of Tocilizumab.

What special dietary instructions should I follow?

• General Diet: There are no specific dietary restrictions with Tocilizumab, but maintaining a balanced diet is important for overall health.
• Cholesterol Monitoring: Since Tocilizumab can increase cholesterol levels, it may be beneficial to follow a heart-healthy diet low in saturated fats and cholesterol.
• Hydration: Stay well-hydrated and avoid excessive alcohol consumption, as dehydration and alcohol can affect liver function.

What should I do if I forget a dose?

• Missed Doses:
  • Subcutaneous Injection: If you miss a dose of Tocilizumab that you administer yourself, follow the instructions provided by your healthcare provider or consult them for guidance on what to do next.
  • Intravenous Infusion: If a scheduled IV infusion is missed, contact your healthcare provider to reschedule as soon as possible.
• Avoid Doubling Up: Do not double up on doses to make up for a missed dose. Follow your healthcare provider’s advice for missed doses.
• Consistent Scheduling: Try to administer or schedule your doses at the same time each period to help remember and maintain consistency.
