Antacids: Taking too many antacids (like Tums) increases the calcium output of the kidneys and concentrates it in the urine predisposing to crystal and stone formation.  Antacids reduce stomach acidity temporarily which may result in impaired ability to digest and absorb certain nutrients such as iron and B Vitamins. Also, healthy stomach acid kills ingested bacteria, viruses and parasites so the addition of antacids may increase the body’s vulnerability to infection to these organisms. Calcium supplements may also bind up certain drugs like ketoconazole which is used as an antifungal agent so that they do not work as effectively. 

Ciprofloxacin : Ciprofloxacin extended-release (long-acting) tablets are used only to treat certain types of urinary tract infections. Ciprofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria.
