A person has been prescribed nitrofurantoin (Furadantin) for a UTI. What education would you provide for them?

The correct answer emphasizes the importance of oral hygiene in relation to the side effects of nitrofurantoin. This medication can cause brown discoloration of the urine, which is a harmless but noticeable effect. However, it can also potentially stain the teeth. To minimize this risk, it is advisable for patients to rinse their mouths after taking nitrofurantoin. This helps prevent any staining from lingering in the mouth for extended periods.

Maintaining good oral hygiene is integral while on medications like nitrofurantoin to prevent dental staining, particularly since the medication remains in the oral cavity temporarily after ingestion. This advice is part of broader patient education about the medication's side effects and how to manage them effectively.
