CBC CBC Medications & Substances in Breastfeeding 2

Question 1

Alcohol consumption while breastfeeding is a common concern. What is the safest guidance for a CBC counselor to provide?

Accepted Answer

Waiting 2–3 hours per standard drink before nursing minimizes infant exposure

Answer

Alcohol clears from milk at the same rate as from blood, so waiting approximately 2–3 hours per drink before nursing minimizes infant alcohol exposure.

Question 2

Which antidepressant class is generally considered most compatible with breastfeeding based on current evidence?

Accepted Answer

Selective serotonin reuptake inhibitors (SSRIs), particularly sertraline and paroxetine

Answer

SSRIs, especially sertraline and paroxetine, have extensive safety data showing low milk transfer and minimal adverse infant effects.

Question 3

A CBC counselor is asked about cannabis use while breastfeeding. What is the most evidence-based response?

Accepted Answer

Cannabis use is not recommended during breastfeeding as THC accumulates in breast milk and may affect infant neurodevelopment

Answer

THC is highly lipid-soluble and accumulates in breast milk; current evidence links infant THC exposure to potential neurodevelopmental concerns.

Question 4

What is the primary concern with codeine use in breastfeeding mothers?

Accepted Answer

Ultra-rapid metabolizers can produce dangerously high morphine levels that transfer into milk, potentially causing infant respiratory depression

Answer

Mothers who are CYP2D6 ultra-rapid metabolizers convert codeine to morphine very quickly, leading to elevated morphine levels in milk that can cause infant sedation or respiratory depression.

Question 5

Which herbal supplement has some evidence suggesting it may decrease milk supply?

Accepted Answer

Sage (Salvia officinalis)

Answer

Sage contains compounds thought to have antiestrogenic and antisecretory effects, and traditionally has been used to dry up milk supply.
