How you take it
One shot under the skin every 4 weeks, from a prefilled syringe you keep in the refrigerator. You or a caregiver give it at home after training.
Before your first dose
- A check that you do not have an infection right now.
- Any live vaccine you need, done at least 30 days before your first shot. Ask your doctor which of your vaccines are live ones.
- Your doctor's office sends a start form to PANTHERx Rare, the specialty pharmacy. You sign it too, which signs you up for Otsuka Patient Services, the drugmaker's support program.
- Your insurance approves the medicine. With private insurance, you may pay as little as $0, and Otsuka may cover a few doses while your plan decides.
- PANTHERx Rare calls you to set up delivery, so answer calls from numbers you do not know that week. A Care Navigator from Otsuka can help you learn to give the shot.
