What are the brand names for the generic drug Nitrofurantoin?

Nitrofurantoin is an antibiotic primarily used to treat urinary tract infections. The brand names associated with Nitrofurantoin are Macrodantin and Macrobid.

Macrodantin is the brand name for the conventional formulation of Nitrofurantoin, while Macrobid is a combination of Nitrofurantoin monohydrate and Nitrofurantoin macrocrystals, designed to enhance gastrointestinal tolerability and efficacy. Both brand formulations are indicated for similar uses, primarily targeting bacteria responsible for urinary tract infections.

The other options consist of medications that serve very different purposes; for example, Micronase and Glucophage are used for diabetes management, Tylenol and Advil are analgesics and antipyretics, and Miralax and Relistor are used for gastrointestinal issues. None of these relate to the antibiotic properties or indications of Nitrofurantoin. This understanding solidifies why Macrodantin and Macrobid is the correct answer.
