- Labeling must not be false or misleading
- •Labeling must include
- 1- listing of active ingredients and quantity and listing of inactive ingredients in alpha order
- 2- “adequate directions for use” and

If drug cannot be labeled with “adequate directions for use”, it must contain “adequate information for use”

- Category C: Either animal studied have shown an adverse effect on the fetus- “only if the potential benefit justifies
- the potential risk to the fetus”
- Category D: Positive evidence of fetal risk
: Studied on animals or humans have demonstrated fetal risk, and that risk in pregnant women clearly outweighs any benefits- “may cause fetal harm when administrated to a pregnant women”
