Forbehandling med anti- inflammatoriske substanser kan medføre yderligere eller øgede bivirkninger, og derfor skal en behandlingsfri periode med sådanne veterinærlægemidler overholdes i mindst 24 timer inden igangsætning af behandling.
Pre-treatment with anti-inflammatory substances may result in additional or increased adverse effects and accordingly a treatment-free period with such veterinary medicinal products should be observed for at least 24 hours before commencement of treatment.
