Satralizumab Medication
Enspryng (Satralizumab) injection is an interleukin-6 (IL-6) receptor antagonist used for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adult patients who are anti-aquaporin-4 (AQP4) antibody positive.
Dosage: The recommended loading dosage of Satralizumab for the first three administrations is 120 mg by subcutaneous injection at 0, 2, & 4 Weeks, followed by a maintenance dosage of 120 mg every 4 weeks. Prior to every use of Satralizumab injection, advise patients to consult with their health specialist in case they suspect an active infection, including localized infections. In case of active infection, delay the use of Satralizumab injection until the infection is resolved.

- Headache

- Arthralgia
- Extremity pain
- Fatigue
- Nausea
- Nasopharyngitis

Warnings and Precautions:
- The enspryng uses are restricted in patients with known hypersensitivity to satralizumab injection or any of the inactive ingredients, active Hepatitis B infection, or active/untreated latent tuberculosis.
- Live or live-attenuated vaccines should not be administered concurrently with enspryng injection dosing because clinical safety has not been established.
- The ALT and AST levels should be monitored every 4 weeks for the initial three months of therapy, followed by every three months for one year.
- Neutrophil counts should be monitored 4-8 weeks after initiation of therapy with Enspryng injection, and thereafter at regular clinically determined intervals.
