The classification for a drug with no evidence of risk in humans is Category B. This category implies that studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester, indicating that the drug is generally considered safe for use during pregnancy. This classification is important for healthcare providers to make informed decisions when prescribing medications to pregnant patients.

In contrast, other categories indicate varying levels of risk. Category A substances have been well-controlled studies and have shown no risk to the fetus, while Category C indicates that risk cannot be ruled out, as there may not be sufficient studies in humans but potential benefits may outweigh the risks. Category D drugs have demonstrated evidence of human fetal risk but may still be prescribed if the benefits to the mother outweigh the risks to the fetus. Understanding these classifications helps healthcare professionals evaluate medication safety during pregnancy and provides guidance on prescribing practices.
