From the FDA Drug Label

If pregnant or breast-feeding, ask a health professional before use. The FDA drug label does not answer the question.

From the Research

For breastfeeding mothers struggling with sleep, the safest medication option is typically low-dose melatonin supplements (1-3mg) taken 30 minutes before bedtime, as melatonin occurs naturally in breast milk and has been shown to have a positive impact on sleep measures without safety issues 1.

Key Considerations

  • Non-medication approaches should be tried first, including consistent sleep schedules, avoiding screens before bed, keeping the bedroom dark and cool, and sleeping when the baby sleeps.
  • If insomnia persists, consult with a healthcare provider before taking any medication, as some prescription sleep aids like zolpidem (Ambien) or eszopiclone (Lunesta) may be considered for short-term use in specific situations, but only under medical supervision due to potential risks.
  • The safety of the infant is paramount, so always discuss any medication with a healthcare provider who can evaluate your specific situation and the age of your baby, as medication effects can vary depending on infant age and development.

Medication Options

  • Melatonin supplements (1-3mg) are a relatively safe option, as melatonin occurs naturally in breast milk and has been shown to have a positive impact on sleep measures without safety issues 1.
  • Diphenhydramine (Benadryl) at 25mg taken 30 minutes before bedtime may also be considered, but it is essential to weigh the benefits and risks, as it can cause sedation and has limited evidence supporting its efficacy and safety in breastfeeding mothers 2, 3.

Importance of Healthcare Provider Consultation

  • Consultation with a healthcare provider is crucial before taking any medication, as they can evaluate the specific situation and the age of the baby, and provide guidance on the safest medication option.
  • Healthcare providers can also help identify underlying sleep disorders or other health issues that may be contributing to insomnia and provide appropriate treatment.
