What dose of Skyrizi (risankizumab) is used for ulcerative colitis (UC)?
Skyrizi dosing for UC depends on the induction schedule (to bring symptoms under control) and then a maintenance regimen (to keep them controlled). Common UC dosing approaches for risankizumab use weight-independent fixed doses given by injection, with the induction period starting at week 0 and follow-up doses given at set intervals, then transitioning to maintenance dosing after induction.
How is Skyrizi given: IV vs injection, and how often?
For UC, Skyrizi is administered by injection (not infusion). The injection schedule is split between:
- Induction dosing early in treatment (higher-frequency dosing over the first several weeks), and
- Maintenance dosing after induction (less frequent dosing to sustain remission).
When do patients usually switch from induction to maintenance?
The transition from induction to maintenance occurs after the induction dosing window ends. That switch timing is fixed in the UC regimen, so the care team typically plans the first “maintenance-dose” injection once induction is complete.
If I miss a Skyrizi dose for UC, what should I do?
If a dose is missed, patients typically follow their prescriber’s guidance rather than trying to “double up.” Because the UC schedule is stepwise (induction then maintenance), the correct action depends on whether the missed dose was during induction or maintenance and how long ago it was due.
Does the dose change for children, older adults, or with prior biologic exposure?
In most antibody dosing regimens for UC, the dose is fixed (not adjusted by age or prior biologic use). What can change is the overall treatment plan—whether Skyrizi is being started as first biologic, after another biologic, or as part of combination therapy.
What are common UC dosing questions patients ask in practice?
Patients often ask about:
- Whether Skyrizi can be taken with other UC meds (like corticosteroids or immunomodulators),
- How long it typically takes to notice improvement,
- What happens if symptoms return (dose timing vs reassessment),
- Safety monitoring, especially around infection risk.
