Tocilizumab Side Effects and Adverse Reactions

Like all medications, Tocilizumab may cause side effects. Some are common and mild, while others are rare but more serious. If you experience any side effects, contact your healthcare provider immediately. You can also schedule a telemedicine visit with one of our providers for advice.

Common Side Effects: These may include upper respiratory infections, headaches, high blood pressure, and elevated liver enzymes. While these side effects are generally mild, they should still be reported to your doctor.

Serious Side Effects: These include severe infections (such as tuberculosis), liver problems, gastrointestinal perforation (a hole in the stomach or intestines), and allergic reactions. If you experience symptoms such as fever, persistent cough, yellowing of the skin, or severe abdominal pain, seek medical attention immediately.

Contraindications for Tocilizumab Treatment

A contraindication is a specific situation or condition where a particular medication should not be used because it may be harmful. Several contraindications should be considered before starting Tocilizumab treatment, including:

Active infections: Tocilizumab can suppress the immune system, making it harder for your body to fight infections. If you have an active infection, taking Tocilizumab could worsen it.

Allergy to Tocilizumab or its ingredients: If you have had an allergic reaction to Tocilizumab or any of its components in the past, you should not take this medication. Allergic reactions can be severe and potentially life-threatening.

Low white blood cell count (neutropenia): Tocilizumab can lower your white blood cell count, increasing the risk of infections. If your count is already low, this medication could further increase that risk.

Low platelet count (thrombocytopenia): Platelets help your blood clot. Tocilizumab can reduce platelet levels, so if you already have a low count, this medication could raise your risk of bleeding.

Elevated liver enzymes: Tocilizumab can cause liver damage, so it should not be used if you have elevated liver enzymes or pre-existing liver disease without careful monitoring by your healthcare provider.

Drug Interactions with Tocilizumab

Tocilizumab can interact with other medications, potentially increasing the risk of side effects or reducing the effectiveness of treatment. Be sure to inform your healthcare provider about all medications you are taking, including over-the-counter drugs and supplements. Some known drug interactions include:

Warfarin (Coumadin): Tocilizumab may reduce the effectiveness of warfarin, a blood thinner, which could increase the risk of blood clots.

Statins (e.g., Atorvastatin [Lipitor], Simvastatin [Zocor]): Tocilizumab can lower statin levels in your blood, potentially reducing their effectiveness in managing cholesterol.

Oral contraceptives (birth control pills): Tocilizumab may reduce the effectiveness of hormonal birth control, increasing the risk of unintended pregnancy.

Cyclosporine (Neoral, Sandimmune): Tocilizumab can decrease cyclosporine levels in your blood, reducing its effectiveness in preventing organ rejection or treating autoimmune conditions.

Live vaccines: Avoid live vaccines while taking Tocilizumab, as the medication suppresses your immune system, making live vaccines less effective and increasing the risk of infection.

Tocilizumab in Pregnancy

Is it Safe to Take Tocilizumab During Pregnancy?

The safety of Tocilizumab treatment during pregnancy remains uncertain. While animal studies suggest potential risks, there is limited data on its effects in pregnant women. Tocilizumab should only be used during pregnancy if the potential benefits clearly outweigh the risks. If you are pregnant or planning to become pregnant, it is essential to consult your healthcare provider. They can help you weigh the risks and benefits and explore alternative treatments if necessary. If you are currently taking Tocilizumab and discover you are pregnant, contact one of our telemedicine providers immediately to discuss your options.

Tocilizumab While Breastfeeding

Is it Safe to Take Tocilizumab While Breastfeeding?

It is unclear whether Tocilizumab passes into breast milk, and there is limited information regarding its safety for breastfeeding infants. Due to the potential for serious side effects in nursing babies, it is generally recommended to either discontinue breastfeeding or stop taking Tocilizumab. Discuss your options with your healthcare provider to determine the best course of action for both you and your baby. Our telemedicine providers are available to assist you in making an informed decision.

Estimated Cost of Tocilizumab

The cost of Tocilizumab can vary depending on the pharmacy and location. Without insurance, a 30-day supply of Tocilizumab, using a GoodRX coupon, is estimated to cost between $1,200 and $2,500, depending on the dosage and form (e.g., injection or infusion). For the most accurate pricing, check with your pharmacy, and consider exploring available financial assistance programs.

Possible Alternatives to Tocilizumab

If Tocilizumab treatment is not suitable for you, there are alternative medications and lifestyle changes that may help manage your condition. Always consult your healthcare provider before making any changes to your treatment plan. Below are some alternatives based on specific conditions:

1. Rheumatoid arthritis: Alternatives include methotrexate, sulfasalazine, or biologics like adalimumab (Humira) or etanercept (Enbrel). Lifestyle changes such as regular exercise, a balanced diet, and stress management can also help alleviate symptoms.
2. Juvenile idiopathic arthritis: Methotrexate, NSAIDs (like ibuprofen), and biologics such as etanercept (Enbrel) or adalimumab (Humira) are potential alternatives. Physical therapy and maintaining an active lifestyle can also be beneficial.
3. Giant cell arteritis: Corticosteroids like prednisone are commonly used. Tocilizumab is often added if steroids alone are not effective. Other immunosuppressants, such as methotrexate, may also be considered.
4. Systemic juvenile idiopathic arthritis: Alternatives include NSAIDs, corticosteroids, or biologics like canakinumab (Ilaris) or anakinra (Kineret). Physical activity and a balanced diet can also support overall health.
5. Cytokine release syndrome: Corticosteroids, other immunosuppressants, and supportive care are potential alternatives. Tocilizumab is often used in severe cases, but other treatments may be considered based on the severity of symptoms.
6. COVID-19: Tocilizumab has been used in severe cases of COVID-19, particularly when there is significant inflammation. Alternatives include corticosteroids like dexamethasone and supportive care, including oxygen therapy and antiviral treatments.
7. Castleman disease: Rituximab (Rituxan) and chemotherapy are potential alternatives. Tocilizumab is often used in cases where other treatments are not effective.
8. Ankylosing spondylitis: NSAIDs, physical therapy, and biologics like adalimumab (Humira) or secukinumab (Cosentyx) are common alternatives. Regular exercise and maintaining good posture can also help manage symptoms.
9. Psoriatic arthritis: Alternatives include methotrexate, NSAIDs, and biologics like ustekinumab (Stelara) or secukinumab (Cosentyx). Maintaining a healthy weight and regular exercise can also improve symptoms.
10. Systemic lupus erythematosus: Hydroxychloroquine (Plaquenil), corticosteroids, and immunosuppressants like azathioprine (Imuran) are common alternatives. Lifestyle changes, such as sun protection and stress management, can also help manage lupus symptoms.

Recent Updates on Tocilizumab Research

Recent studies have explored the use of Tocilizumab in treating severe cases of COVID-19, particularly in patients who develop a hyperinflammatory response known as cytokine release syndrome. Research has shown that Tocilizumab can reduce the risk of death in some patients with severe COVID-19, especially when used alongside corticosteroids. Ongoing studies are also investigating its long-term safety and effectiveness in treating other autoimmune conditions, such as systemic lupus erythematosus and ankylosing spondylitis.

As new research continues to emerge, staying informed is crucial. Discuss any updates with your healthcare provider. If you have questions about whether Tocilizumab treatment is right for you, our telemedicine providers are available to help you make an informed decision based on the latest evidence.
