What is the pregnancy category for Cephalexin?

The correct pregnancy category for Cephalexin is Category B. This designation indicates that animal studies have not shown any evidence of harm to the fetus, and there are no adequate and well-controlled studies in pregnant women, but potential benefits of the drug may outweigh any potential risks. Category B drugs are generally considered safer for use during pregnancy compared to Category C, where animal studies have shown an adverse effect, or Category A, where adequate studies in pregnant women have not demonstrated risk.

The confusion might stem from mischaracterizing Cephalexin's safety profile, leading to the answer indicating "None," which fails to recognize its classification. Understanding the nuances of these categories is important for ensuring the safety of both the mother and the developing fetus when prescribing medications during pregnancy.
