På grund af thalidomids potentiale for at fremkalde bradykardi bør forsigtighed udvises ved samtidig brug af lægemidler, der har samme farmakodynamiske virkning, såsom betablokkere, kolinesterasehæmmere og aktive stoffer, der vides at kunne inducere torsade de pointes.
Due to thalidomide’ s potential to induce bradycardia, caution should be exercised with medicinal products having the same pharmacodynamic effect such as active substances known to induce torsade de pointes, beta blockers or anticholinesterase agents.
