USES
Benlysta is provided in two forms of administration: intravenous (IV) infusion and subcutaneous (SC) injection.
Intravenous Infusion: When given intravenously, Benlysta is administered by a healthcare professional in a clinic or hospital setting. The infusion is usually given over a period of an hour. The initial dosing schedule involves an infusion every two weeks for the first three doses, followed by once monthly thereafter. This schedule may be adjusted based on the patient’s response and clinical needs.
Benlysta is also available as a self-administered subcutaneous injection. Patients who are stable and have been trained by their health care provider can administer the medication at home. The usual dose is 200 mg administered once a week.
Both ways of administration are effective in the treatment of lupus symptoms, and the choice between them depends on the patient’s preference and how well he or she tolerates the infusion.
WORKING
The mechanism of action of Benlysta is its binding to the B-lymphocyte stimulator, which is a protein critical for the survival and differentiation of B cells. In SLE, an increased level of BLyS contributes to the survival of autoreactive B cells, which in turn produce autoantibodies that attack the body’s tissues. Benlysta prevents BLyS from interacting with B cells because it binds to BLyS.
Therefore, the attack of B cells is restrained, and the production of autoantibodies is reduced with a decrease in the attack of the immune system to the body’s own tissues. This process reduces inflammation and prevents further damage of organs and tissues, usually affected by lupus such as the kidneys, skin, joints, and heart.
SIDE EFFECTS
While Benlysta is usually well tolerated, it may cause side effects. The most common side effects include:
Infusion-related reactions (for IV administration): These may include fever, chills, nausea, and headaches. Reactions typically occur during the infusion and usually resolve once the infusion is completed.
Infections: Because Benlysta modulates the immune system, it may increase the risk of infections, including upper respiratory infections, sinusitis, and urinary tract infections.
Headache: Most common side effect, typically during the initial stages of therapy.
Diarrhea: Patients may experience gastrointestinal side effects such as diarrhea.
Nausea: Nausea is another common side effect, especially after infusion.
Fatigue: Patient may feel tired, but it is more common when the treatment is initiated.
WARNINGS
Infections: As Benlysta can compromise the immune system, patients must be observed for signs of infection. Patients should seek medical attention if they notice new symptoms of infection such as fever, chills, or cough.
Mental Health: Benlysta was associated with a heightened tendency of mood changes such as depression and suicidal thoughts. Patients receiving Benlysta should be observed for changes in moods or behaviors, primarily at the beginning of their treatment.
Vaccinations: Patients starting treatment under Benlysta should first be vaccinated up to live vaccines. Live vaccines tend to be interfered by Benlysta.
Pregnancy and Breastfeeding: Benlysta is indicated as Category C for pregnancy. Thus, it should only be employed if the potential benefit to the patient justifies the potential risk to the fetus. It is unknown if Benlysta passes into the breast milk; hence, breastfeeding mothers should consult their healthcare provider before taking the drug.
INTERACTIONS
Immunosuppressants: Combining Benlysta with other immunosuppressive drugs may increase the risk of infections due to a weakened immune system, requiring close monitoring.
Vaccines: Benlysta may reduce the effectiveness of live vaccines, so it’s important to avoid receiving live vaccines during treatment and consult your doctor before any vaccinations.
Biologic Drugs: Using Benlysta with other biologic therapies may increase the risk of serious infections or adverse effects, requiring careful supervision by a healthcare provider.
Anticoagulants: Benlysta may interact with blood thinners, increasing the risk of bleeding or bruising.
DOSAGE
Adults with lupus: Recommended dosage:
IV Infusion: 10 mg/kg every two weeks for the first three doses, then once a month thereafter.
Subcutaneous Injection: The recommended dose is 200 mg once a week.
For pediatric patients (ages 5 and older), the dosage is based on body weight and will be determined by the prescribing doctor.
PRESCRIPTION
Benlysta is a prescription medication. Therefore, only after getting a prescription from a doctor is it possible to receive it. A confirmed diagnosis of systemic lupus erythematosus should occur prior to treatment.
Before administering the drug, all infections, mental conditions, and kidney functions in a patient’s medical history need to be evaluated carefully.
