Can I give my child Cetix and Grintuss Pediatric at the same time?

I do not find information on the interaction of the ingredients contained in Grintuss Pediatric syrup (honey, plantain leaf extract, grindelia tops extract, immortelle inflorescence extract) with cefixime, the active substance of Cetix. I see no contraindications to the simultaneous use of these preparations.
