Simplifying Therapy for Stiff-Person Syndrome

Diplomat combines clinical expertise with personalized care.

Through treatment and patient education, Diplomat Specialty Infusion Group is proud to support patients with stiff-person syndrome (SPS). Patients with SPS often experience symptoms involving progressive muscle rigidity and prolonged — often severe — muscle spasms.

While SPS is primarily a rare disease of the nervous system, autoimmune disorders are also common in these patients. Diplomat does more than provide immune globulin therapies, muscle relaxers, and pain relievers to patients in need. We guide patients every step of the way — seeking third-party financial assistance, managing side effects, and offering a listening ear 24/7.
