When and How to Use ItSome general considerations to keep in mind during treatment with Arcalyst include the following:
- This medication is injected just beneath the skin (subcutaneously) once a week.
- Arcalyst comes as a powder. It is mixed with Sterile Water for Injection before use. Your pharmacy can supply you with Sterile Water for Injection when you receive your medicine.
- Your healthcare provider will show you or your caregiver how to properly use this medicine. Make sure you understand how to prepare and inject your dose before starting treatment. Talk to your healthcare provider if you are unsure about anything related to your Arcalyst injection.
- The injections can be given in the abdomen (stomach), upper arm, or thigh. You should rotate the site of your injection each week.
- Do not inject skin areas that are red, bruised, tender, or hard.
- For this drug to work properly, it must be used as prescribed.
Dosing InformationThe dosage your healthcare provider recommends will vary, depending on your age and your weight (in children). As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
