Macrodantin is an antibiotic used primarily to treat urinary tract infections caused by susceptible bacteria. It works by targeting several processes that are necessary for the bacterial cells to reproduce. The active ingredient in Macrodantin is nitrofurantoin, specifically as the macrocrystals (large crystals). Macrodantin is similar to Furadantin, which contains nitrofurantoin in smaller crystals. The macrocrystals in Macrodantin seem to cause less nausea, vomiting, diarrhea and stomach upset than the smaller crystals cause.
