Lemtrada (alemtuzumab) is a medication primarily used to treat relapsing forms of multiple sclerosis (MS). It works by targeting and depleting certain immune cells, specifically CD52-positive lymphocytes, which play a role in the autoimmune attack on the nervous system. Because Lemtrada profoundly affects the immune system, managing its administration and potential interactions with other drugs, such as steroids, is important.
Steroids, also known as corticosteroids, are commonly used in MS treatment to reduce inflammation and manage acute relapses. They work by suppressing the immune response and decreasing inflammation through multiple mechanisms, including inhibiting inflammatory gene expression and reducing immune cell migration. Common steroids used in MS include methylprednisolone and prednisone.
**Can Lemtrada be taken with steroids?** Yes, Lemtrada is often administered in conjunction with steroids, but the timing, dosage, and purpose of steroid use are carefully controlled. Steroids are typically given before or during Lemtrada infusions to reduce infusion-related reactions and inflammation. This is a standard practice because Lemtrada’s mechanism of action can cause immune activation and cytokine release during the initial treatment phase, which steroids help to mitigate.
Here is a detailed explanation of how Lemtrada and steroids interact and why they are used together:
– **Steroids reduce infusion reactions:** When Lemtrada is infused, it can trigger an immune response that leads to symptoms such as fever, rash, headache, nausea, and more severe cytokine release syndrome. Administering steroids before Lemtrada infusions helps blunt this immune activation, making the treatment safer and more tolerable.
– **Steroids manage inflammation:** Lemtrada’s immune cell depletion can cause transient inflammation or immune system disturbances. Steroids help control this inflammation, especially during the early treatment period.
– **Steroids do not interfere with Lemtrada’s long-term effect:** While steroids suppress the immune system temporarily, Lemtrada’s main therapeutic effect comes from the long-term depletion and subsequent repopulation of immune cells. Short courses of steroids used around Lemtrada infusions do not negate its efficacy.
– **Steroid dosing and duration:** Typically, high-dose intravenous steroids such as methylprednisolone are given for a few days before or during Lemtrada infusions. After this, steroids are tapered off or stopped. Prolonged steroid use alongside Lemtrada is generally avoided due to the risk of excessive immunosuppression and side effects.
– **Monitoring for infections:** Both Lemtrada and steroids suppress the immune system, increasing the risk of infections. Patients receiving this combination require close monitoring for signs of infection and may need prophylactic treatments to reduce infection risk.
– **Avoiding overlapping immunosuppression:** Because Lemtrada causes long-lasting immune cell depletion, adding steroids beyond the initial infusion period or using other immunosuppressants simultaneously can increase the risk of serious infections and complications. Therefore, steroids are used cautiously and usually only around the time of Lemtrada administration.
– **Steroids for relapse management:** In some cases, patients treated with Lemtrada may still experience MS relapses. Steroids remain the first-line treatment for these relapses, even after Lemtrada therapy, but again, the use is typically short-term and carefully managed.
In summary, steroids and Lemtrada are often used together, but in a controlled manner. Steroids serve mainly to reduce infusion-related side effects and manage inflammation during Lemtrada treatment. They do not diminish Lemtrada’s effectiveness when used appropriately. However, prolonged or unsupervised steroid use with Lemtrada is not recommended due to the increased risk of immunosuppression and infections. Patients receiving Lemtrada should be closely monitored by their healthcare providers to balance the benefits and risks of combined steroid use.
