Corticosteroids and immunosuppressor treatments may interfere with antibody production and cause the vaccination to fail. Therefore, it is preferable to conduct a neutralizing antibody assay 2 to 4 weeks after the last injection of vaccine.
Rabies immunoglobulins and vaccine must never be combined in the same syringe or administered at the same site.
When possible, the vaccine should be administered contralaterally to the immunoglobulins administration sites.
In order to avoid possible interactions between several medicinal products, any other ongoing treatment should be systematically reported to the doctor or to the pharmacist.
