Subcutaneous therapy may be initiated with or without an IV loading dose. The IV loading dose (if given) should be based on weight and followed by the first subcutaneous injection within a day of the IV infusion.
See abatacept IV monograph for details of weight based IV dosing.
Patients switching from IV to subcutaneous therapy should administer the first subcutaneous dose instead of their next scheduled monthly IV dose.
Treatment with csDMARDs (e.g., methotrexate) may be continued during treatment with abatacept.
Patients with rheumatoid arthritis who are in remission or have low disease activity may have their dose of abatacept down-titrated by their rheumatologist.
The use of abatacept in combination with other cytokine modulators (e.g. TNF-alpha inhibitors, rituximab, anakinra, tocilizumab) is not recommended due to increased risk of infection.
Abatacept is contraindicated in serious or untreated infection, e.g. sepsis, abscess, hepatitis B, active TB (before completing TB treatment).
May reactivate inactive hepatitis B and latent TB (begin TB treatment before starting abatacept).
Patients with suspected latent or active TB should be treated in consultation with an Infectious Diseases physician.
Live vaccines should not be given concurrently with abatacept or within 3 months of discontinuation.
