From the Research

It is generally considered safe to take Dayquil while breastfeeding, but caution and consultation with a healthcare provider are advised. Dayquil typically contains acetaminophen, dextromethorphan, and phenylephrine, which pass into breast milk in small amounts 1. If you need to take it, use the lowest effective dose for the shortest time possible, and try to time doses right after nursing to minimize exposure to your baby. Single-ingredient medications are preferable when breastfeeding, so consider taking just acetaminophen for fever or pain rather than multi-symptom formulas.

Some key points to consider when taking Dayquil while breastfeeding include:

  • Watching for any unusual drowsiness, irritability, or feeding changes in your baby after taking Dayquil
  • Avoiding phenylephrine while nursing as it can potentially reduce milk supply in some women
  • Considering natural remedies like rest, hydration, saline nasal sprays, and honey (if you're not adding it to your baby's food) to manage cold symptoms with less concern about medication effects
  • Consulting with your healthcare provider before taking any medication while breastfeeding, as they can provide personalized advice and guidance

According to the most recent study on the topic, most drugs are transferred from the mother's blood to the milk, but the breastfed infant usually ingests a small drug amount through human milk 2. This study emphasizes the importance of risk assessment and considering the benefits associated with breastfeeding, the risks of untreated maternal disease, and the maternal willingness to breastfeed.

In terms of specific guidance, the American Academy of Pediatrics (AAP) considers acetaminophen and ibuprofen to be compatible with breastfeeding 3. However, it is essential to use these medications at the lowest effective dose and for the shortest duration necessary. Additionally, healthcare providers should always assume that mothers will be concerned and use risk communication as a key to ensure medication adherence and prevent unnecessary interruption of breastfeeding 2.

Overall, while Dayquil can be taken while breastfeeding, it is crucial to exercise caution, consult with a healthcare provider, and consider alternative remedies to minimize exposure to your baby.
