A breastfeeding mother is prescribed fluoroquinolone antibiotics. What should a CBC counselor communicate?

Fluoroquinolones are completely safe and require no monitoring

Answer

All fluoroquinolones are absolutely contraindicated during breastfeeding

Answer

They must be avoided for the full duration of breastfeeding

Question 2

What is the significance of a drug's milk-to-plasma (M/P) ratio in breastfeeding counseling?

Accepted Answer

A high M/P ratio indicates the drug concentrates in breast milk relative to maternal plasma, increasing infant exposure risk

Answer

A high M/P ratio means the drug is safer because it stays in milk rather than passing to the infant

Answer

The M/P ratio is not clinically useful and should be ignored

Answer

An M/P ratio above 1 means the drug is automatically contraindicated

Answer

Metformin is absolutely contraindicated during breastfeeding
