How do I take certolizumab pegol and how long does it take to work?
Certolizumab pegol is taken as an injection under the skin (subcutaneous injection) using a pre-filled pen-like syringe. You, your partner, or another family member can learn to give the injections at home.
Each pre-filled syringe contains 200 mg. Your doctor will advise on the correct dose – usually 400 mg (two syringes) once every two weeks for the first three doses, then 200 mg (one syringe) every two weeks.
How long does certolizumab pegol take to work?
If certolizumab pegol works for you, you'll probably feel better in 2–12 weeks. Because it's a long-term treatment, it's important to keep taking certolizumab pegol (unless you have severe side-effects):
- even if it doesn't seem to be working at first
- even when your symptoms improve (as this will help to keep the disease under control).
If you forget a dose of certolizumab pegol, take the next dose as soon as you remember. Then continue according to your original schedule.
