Pregnancy Categories:    

Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester.

Category B: No evidence shown of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women

Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a result in humans must take care of potential risks in pregnant women

Category D: There is adequate data available with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits

Category X: Drugs listed in this category outweigh risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.

Category N: There is no data available for the drug under this category

Pregnancy warnings:  

AU TGA pregnancy category: B2

Pregnancy Categories:    

Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester.

Category B: No evidence shown of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women

Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a result in humans must take care of potential risks in pregnant women

Category D: There is adequate data available with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits

Category X: Drugs listed in this category outweigh risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.

Category N: There is no data available for the drug under this category
