What happens if you miss a dose of Agalsidase beta Injection?
Last updated September 7, 2026.
**If you miss a dose of agalsidase beta injection, contact your infusion center or specialist right away to reschedule; the dose is usually given as soon as it can be arranged rather than skipped.** Agalsidase beta is given as an intravenous infusion about every two weeks in a clinic, hospital, or at home with a nurse, so a missed dose is really a missed appointment. Your care team will usually rebook the infusion within a few days instead of waiting for the next scheduled one, and they will not double the amount to make up for lost time. If you take premedication such as an antihistamine or acetaminophen before infusions, keep taking it as directed for the rescheduled visit. A gap of several weeks is worth a call to your metabolic or genetics specialist, who may want to review your symptoms and lab work. Booking the next infusion before you leave each visit, plus a calendar reminder, keeps the every-two-week rhythm steady.
What to do
- Call the same day: Let your infusion center know as soon as you realize you will miss a visit so they can offer the next open slot.
- Skip the catch-up dose: Never ask for a larger or extra infusion to make up for a missed one; the schedule resumes at the usual dose.
- Keep premedication as directed: If you normally take an antihistamine or acetaminophen before infusions, follow the same plan for the rescheduled visit.
- Book before you leave: Schedule the next infusion at the end of each visit and set a phone reminder two days ahead.
- Plan travel early: Tell your team weeks in advance about trips so they can shift a date or arrange infusion at another site.
- Report returning symptoms: Tell your metabolic or genetics specialist if pain, stomach problems, or fatigue increase after a long gap.
