The U.S. FDA officially phased out its A, B, C, D, and X pregnancy letter categories in 2015, replacing them with a more detailed narrative format. Yet, understanding **what is category C** remains relevant, as it provides important context for why the system was modernized and how drug risk during pregnancy is communicated today.

Before 2015, the U.S. Food and Drug Administration (FDA) classified amoxicillin as Pregnancy Category B. This historical classification is important, but it's crucial for pregnant individuals to understand the modern Pregnancy and Lactation Labeling Rule (PLLR) that has since replaced the letter-based system.

For years, cefdinir was classified as a pregnancy Category B medication by the FDA, signifying a lack of demonstrated risk to a fetus in animal studies but no controlled human data. However, in 2015, the FDA deprecated this letter-based system and replaced it with a more detailed narrative format under the Pregnancy and Lactation Labeling Rule (PLLR).

While many older medications were once categorized by the U.S. Food and Drug Administration (FDA) with letter grades for pregnancy risk, this system was replaced in 2015. Previously, amoxicillin was indeed categorized as Pregnancy Category B, indicating animal studies showed no risk, but human data was limited.

The United States Food and Drug Administration (FDA) phased out the traditional A, B, C, D, and X pregnancy risk categories in 2015, yet the term “what are category B medications?” remains a common question. This classification was designed to offer guidance on medication use during pregnancy, but was ultimately replaced by a more detailed, evidence-based system for a clearer understanding of risk.

While many women once relied on the FDA's A, B, C, D, X drug category system, it was officially overhauled starting in 2015 to provide more detailed safety information. To accurately answer, "Is class B safe in pregnancy?", one must understand that this classification is now outdated and requires looking at modern, evidence-based data.
