Postpartum Depression Treatment: Medication Options and Breastfeeding Considerations

This podcast episode, part two of a series on women's mental health by Dr. Tracey Marks, focuses on the treatment of postpartum depression (PPD) occurring within four to six weeks of childbirth. It introduces Zulresso (Brexanolone), the first FDA-approved drug specifically for severe PPD, administered as a 60-hour IV infusion, noting its serious side effects like excessive sedation and the need for controlled conditions and a monitoring system. For moderate to severe PPD, the discussion shifts to antidepressants, emphasizing the critical decision of taking these medications while breastfeeding.

The episode delves into the pharmacokinetics of drugs passing into breast milk via diffusion from blood vessels to milk glands. A key distinction is made regarding medication half-life, recommending drugs with a shorter half-life to minimize accumulation in the baby. Specific antidepressants like Fluoxetine (Prozac) and Vortioxetine (Trintellix) are advised against due to their long half-lives, while Nortriptyline, Paroxetine, and Sertraline are highlighted as preferred options based on a 2004 study. Lithium is strongly contraindicated during breastfeeding due to its danger to the infant.

Practical advice includes timing breastfeeding sessions to avoid the medication's peak plasma concentration (Cmax) in the mother's bloodstream, ideally feeding just before or after taking a dose. Dr. Marks explains how to find Tmax information and provides an example using Sertraline. She stresses the importance of monitoring the baby for signs of drug effects, such as irritability, poor feeding, or uneasy sleep. The episode also briefly covers non-pharmacological treatments like Interpersonal Psychotherapy (IPT), Cognitive Behavioral Therapy (CBT), Bright Light Therapy, and Electroconvulsive Therapy (ECT).

Finally, the podcast underscores the severe negative consequences of untreated PPD, which can harm the mother-infant bond and lead to long-term developmental issues like anxiety in children, extending into toddler and young child stages. It encourages mothers to discuss treatment options with their doctors, including obstetricians, highlighting that addressing PPD early is crucial for both maternal and child well-being. The episode serves as a comprehensive guide to navigating PPD treatment while considering the unique challenges of new motherhood.

"Zulresso... it's the first drug specifically indicated for postpartum depression."

"How depressed do you need to be to get this treatment? Probably suicidal or so dysfunctional that you're not eating or you're not sleeping and therefore you're unable to take care of your baby."

"Most drugs pass through to breast milk it's a much smaller amount than you're getting but it's still some."

"The best choice is a medication with a shorter half-life."

"Fluoxetine also knows known as prozac has a very long half-life and has been shown in case reports to be detectable at pretty decent levels in the baby's bloodstream."

"The preferred medications for breastfeeding were nortriptyline paroxetine and sertraline because these drugs did not pass through to the baby in significant quantities."

"You do not want to take lithium if you're breastfeeding lithium passes on through to your breast milk and can be dangerous to the baby."

"The best time to breastfeed would be just before you take your next dose or just after you take it."

"You should always watch for signs that your baby is being affected by your medication and some of these signs would be irritability poor feeding in uneasy sleep."

"Untreated depression has negative effects on your child's development it affects the mother-infant bond which affects your baby's stability."
