What is the usual Skyrizi (risankizumab) dosing schedule?
Skyrizi dosing depends on the condition being treated, but the standard pattern is an initial loading phase followed by maintenance dosing.
For plaque psoriasis, the typical regimen is:
- 150 mg by injection (two 75 mg injections) at weeks 0, 4, and 8
- Then 150 mg every 12 weeks starting after week 8 [1]
For psoriatic arthritis, Crohn’s disease, and ulcerative colitis, dosing can differ by condition and may also include an initial loading phase followed by maintenance dosing. If you tell me the condition you’re asking about, I can narrow it to the exact schedule.
How do I take Skyrizi—how often are the injections?
After the starting doses, Skyrizi is usually given:
- Once every 12 weeks for plaque psoriasis maintenance [1]
The injection is typically self-administered at home after training, but dosing timing should follow your prescription schedule.
What if I miss a Skyrizi dose?
If you miss a dose, follow your prescriber’s guidance on when to take the next dose. Because the correct timing depends on how far along you are in the dosing schedule (loading vs maintenance), the safe answer is to align the next dose with your plan rather than restarting unless your clinician tells you to.
If you share whether you missed a week 0/4/8 loading dose or a later maintenance dose, I can help you map the schedule.
Does weight or age change Skyrizi dosing?
For plaque psoriasis dosing, the standard 150 mg regimen is used as written in the prescribing guidance [1]. Dose adjustments based on weight are generally not the way Skyrizi is dosed for plaque psoriasis, but age and comorbidities still matter for prescribing decisions and monitoring.
How should Skyrizi be stored and handled?
Skyrizi is an injectable biologic and should be stored according to the package instructions (refrigeration and protection from light are common requirements for biologics). Use it only as directed for your specific pen or prefilled syringe type.
Where can I find the exact dosing for my condition?
The dosing schedule differs by indication (for example, plaque psoriasis versus inflammatory bowel disease). If you answer these two questions, I’ll give the exact week-by-week regimen:
1) What are you taking Skyrizi for (plaque psoriasis, psoriatic arthritis, Crohn’s, or ulcerative colitis)?
2) Are you using the on-body/injection pen or prefilled syringe (if you know)?
