Hello You are having dizziness and taking propranolol & clonazepam from last 2 months and still no relief. Now advised cifran ( ciprofloxacin 500 mg ) . In my opinion you can take these medicine together but I doubt that these drugs will cure dizziness . There are so many reasons of dizziness , these includes. 1 Hyper tension or hypo tension , diagnosis can be confirmed by physical examination at the time of dizziness. 2 Mineires s disease , diagnosis can be confirmed by examination by an E N T doctor. 3 Anemia is another one such cause of dizziness, so get in blood examination for hemoglobin level. There are so many other reasons of dizziness as hypoglycemia , hyperglycemia , hyper acidity . In my opinion you must consult another doctor for dizziness ( 2nd ) and get his opinion. Good luck.
