Hi Dear, Understanding your concern. As per your query you are prescribed with two antibiotic combination such as Flucloxacillin and Amoxicillin for two different conditions which is entirely safe to use. Don t panic about anything, you need not to stop Flucloxacillin. In market combination of these two drugs is available as well so you can go for that. You have to take few preventive measures while using this combination i.e take it with a meal which may however minimize stomach irritation, diarrhea and nausea which is a major side effect of antibiotics. Don t discontinue it in between as premature discontinuation may cause symptoms to recur, or cause bacterial resistance. This combination is entirely safe still you can consult your medical practitioner for your condition. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
