I couldn't say for sure but I would doubt ketamine would cause any problems with an antibiotic. Haven't heard of or experienced any problems combining them but have never used that particular antibiotic. Check out the B&D Psychedelics and Medication Interactions thread in my sig - may have been mentioned in there somewhere. This thread may well be merged in with it should any further light be shed on the matter too
