How do you calculate the relative infant dose of a medication?

To calculate the relative infant dose of a medication, the formula used is the infant dose divided by the maternal dose. This approach provides a clear understanding of how much medication an infant is exposed to in relation to the amount taken by the mother.

By performing this calculation, healthcare professionals can assess the potential risk of medication transfer through breastfeeding. A lower relative infant dose indicates a lower risk, enhancing the safety profile for breastfeeding mothers who may need to take medications. This ratio helps guide decisions regarding medication use in lactating women, ensuring both maternal health and infant safety are prioritized.

This method emphasizes the importance of understanding both the maternal and infant dosages, allowing for informed clinical decision-making when it comes to breastfeeding and medication management.
