FDA Class A pregnancy risk - Safest drugs as studies have shown that these drugs have failed to
demonstrate the risk of fetal harm
FDA Class B pregnancy risk - Slightly more of a risk, as human studies show no risk to the fetus
during first trimester, but in animals the drug can do harm on the offspring
FDA Class C pregnancy risk - Greater risk, but animal studies show risk for fetal harm but no
studies have been done on humans to show fetal harm
FDA Class D pregnancy risk - There is a proven risk for fetal harm, but benefits of use during
pregnancy must outweigh the risks.

let in and out of a membrane, safer to use!

quickly, and breastmilk quickly, causing potential harmful effects on the person and the
fetus.
