Individual results may vary based on several factors, including severity of disease, initiation of treatment, and duration of therapy.


Safety & side effects

Common side effects

In clinical studies, the most common side effects of SPINRAZA included lower respiratory infection, fever, constipation, headache, vomiting, back pain, and post-lumbar puncture syndrome (headache related to the intrathecal procedure).

Blood and urine testing

Because an increased risk of bleeding and kidney damage has been seen in similar medications, individuals taking SPINRAZA may be at similar risk.

It is recommended that your healthcare provider (HCP) perform blood and urine testing once before treatment and again before each dose to monitor for signs of these risks.
