Paroxetin bør ikke gives til patienter sammen med thioridazin, da paroxetin ligesom andre lægemidler, der hæmmer leverenzymet CYP450 2D6, kan øge plasmaniveauet af thioridazin (se 4. 5 Interaktion med andre lægemidler og andre former for interaktion).
Paroxetine should not be used in combination with thioridazine, because, as with other drugs which inhibit the hepatic enzyme CYP450 2D6, paroxetine can elevate plasma levels of thioridazine (see section 4.5 Interactions with other medicinal products and other forms of interaction).
