I’m taking similar for my hayfever/seasonal stuff here. I put cetereizine through the interactions tool and it came up orange and it went further to say that this particular antihistimine shares enzymes with the daclatasvir??? Probably nothing that would impact and there is no research, so I’ve decided to steer clear and opted for laratadine which is green lighted. It’s a shame because friends swear by the ceterezine. Em
