Pregnancy Category Classification

Pregnancy category classification established regulatory framework addressing fetal exposure risk. Category A demonstrates no fetal risk in controlled trials. Category D evidence suggests fetal risk but benefits may justify use. Category X demonstrates fetal risk exceeding any benefit. Evolving classification emphasises individualized risk-benefit assessment.

Regu1atory labelling communicates pregnancy implications. Pregnancy registries monitor exposed pregnancies. Therapeutic alternatives guide provider decision-making. Patient counselling addresses pregnancy planning. Post-approval surveillance detects unexpected fetal effects.
