Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Rituxan (rituximab) and Actemra (tocilizumab) are both used to treat autoimmune conditions, but they work in different ways and treat different conditions. Rituxan (rituximab) is a monoclonal antibody that targets B cells, which can be involved in blood cancers and autoimmune diseases like rheumatoid arthritis. It is given as an intravenous infusion and can cause serious infusion-related reactions. Actemra (tocilizumab), on the other hand, is an interleukin-6 (IL-6) receptor antagonist that blocks a chemical causing inflammation and fever. It treats conditions like rheumatoid arthritis and giant cell arteritis and can be given as an infusion or an injection under the skin. Actemra (tocilizumab) also has a biosimilar called Tofidence, while Rituxan (rituximab) has several biosimilars, but they don't all treat the same conditions. Both medications can increase the risk of infections, but Actemra (tocilizumab) can also cause liver problems and high cholesterol.
Actemra (tocilizumab) is an interleukin-6 (IL-6) receptor antagonist. It treats several inflammatory conditions in children and adults, including rheumatoid arthritis. It works by blocking IL-6, a chemical released by the immune system that causes inflammation and fever. Actemra (tocilizumab) is given as an injection (either through the veins or under the skin), typically weekly or every few weeks, depending on the condition you're taking it treat. There's also a biosimilar medication (Tofidence) available but it doesn't treat all the conditions that Actemra (tocilizumab) is approved for. Side effects of Actemra (tocilizumab) include a higher risk of infections and headache.
Please note: The side effects you experience might be differ depending on why you're taking Actemra (tocilizumab) and whether you're receive it IV or SC.
