“When I talk to my patients about self-injection using the VYVGART Hytrulo prefilled syringe, they have questions. I’m passionate about listening to their unique challenges and goals, and providing answers that help them understand their treatment choices. And now, I’m happy to share a few answers with you, too.”
Q: What is different about the VYVGART Hytrulo prefilled syringe for self‑injection?
A: Unlike treatments that require visits to an infusion center, VYVGART Hytrulo can be self-injected at home, or wherever you go using the prefilled syringe.* It’s a subcutaneous injection, meaning it’s injected under the skin, and takes about 20-30 seconds to inject.* That said, you can still get VYVGART Hytrulo injections from a healthcare provider in a doctor’s office or clinic, if that’s what you prefer.
Q: How do I learn to self-inject?
A: This is a common question! You’ll get in-person training at home or at your doctor’s office until you’re ready to inject on your own. The same goes for your caregiver, if they’ll be giving the injections. And you’ll get a demonstration kit to help you learn, with an empty syringe and a block to practice on.
Q: How does dosing work with VYVGART Hytrulo?
A: VYVGART Hytrulo is given in treatment cycles. Each treatment cycle is 4 treatments, 1 given each week, with a personalized break between each cycle. You and your doctor will decide the length of your break based on your symptoms and side effects.
Here’s an example of how that can work. I might start a patient with a break of 4 weeks between treatment cycles. Then, if their symptoms aren’t returning yet after 4 weeks, we talk about extending that break. We keep an eye on their symptoms as we go, and tailor their break to their needs. VYVGART Hytrulo allows us the flexibility to do that.
