Purpose

Medical Conditions or Problems:

• Systemic Lupus Erythematosus (SLE)
• Lupus Nephritis

Goals:

• Reduce disease activity
• Prevent flare-ups
• Improve quality of life by decreasing symptoms like pain and fatigue

Indications

Specific Symptoms or Conditions:

• Persistent, active SLE despite standard therapy
• Autoimmune-driven inflammation not adequately controlled by other treatments

Patient Criteria:

• Diagnosed with SLE or lupus nephritis
• Adults and children aged 5 years and older

Preparation

Procedure Description

1. Initial Assessment: Healthcare providers assess your vital signs and review your medical history.
2. Preparation: The site for the injection (usually the upper arm, thigh, or abdomen) is cleaned with an antiseptic wipe.
3. Injection: Using a syringe, a healthcare professional administers the belimumab injection subcutaneously or intravenously.
   • Subcutaneous Injection: It’s injected just under the skin.

Personnel

• Registered Nurse (RN) or healthcare provider trained in injections and infusions
• Doctor for supervision and immediate medical care

Risks and Complications

Common Risks:

• Injection site reactions (pain, redness, swelling)
• Mild allergic reactions (rash, itching)

Rare Risks:

• Severe allergic reactions or anaphylaxis
• Infections due to immune suppression

Possible Complications:

• Management involves antihistamines for mild reactions, or epinephrine and emergency medical care for severe reactions.

Benefits

• Alleviation of lupus symptoms may begin to be noticed within a few weeks to months.
• Reduces frequency and severity of disease flare-ups.
• Improved overall quality of life.

Recovery

Post-Procedure Care:

• Monitor the injection site for any adverse reactions.
• Normal activities can usually be resumed immediately unless otherwise directed by your doctor.

Expected Recovery Time:
