What information is NOT included in the box warning for Nitrofurantoin?

The box warning for Nitrofurantoin typically includes critical safety information that highlights the potential risks associated with the drug. This includes the risk of pulmonary toxicity, which can lead to serious lung issues, and specific contraindications related to the medication's use, such as its avoidance in individuals with severely impaired renal function due to the risk of toxicity.

On the other hand, while safety in pregnancy is an important consideration when prescribing medications, it is not a part of the boxed warning. The boxed warning is reserved for the most serious risks and adverse effects associated with a drug, rather than general safety information related to specific populations like pregnant individuals. Thus, the correct answer reflects that safety in pregnancy is not included in the boxed warning for Nitrofurantoin.
