Breastfeeding and over-the-counter medications

Why does the need for medication become a barrier to breastfeeding? A narrative review

PROBLEM

The need for medication during lactation can contribute to the early cessation of breastfeeding.

BACKGROUND

Breastfeeding women may require medication for acute or chronic health conditions. For some women this need for medication can become a barrier to breastfeeding; this is despite the fact that the majority of medications are considered to be compatible with lactation.

AIM

This narrative review aims to investigate factors relating to medicines safety that could contribute to medication unnecessarily becoming a barrier to breastfeeding.

METHODS

A selective literature search using PubMed, Scopus and Google Scholar was conducted over a 6-month period using the search terms "breastfeeding", "lactation", "medication" and "information". Articles were assessed to identify whether they addressed the impact of medication use on the decision to breastfeed.

FINDINGS

Fifty six articles were identified as having appropriate discussion about decision making for the safe use of medication during lactation. Themes identified included variable and conflicting safety advice for medicines; difficulty interpreting risks associated with medicine use; societal pressures faced by the breastfeeding woman; and the varied knowledge and training of health professionals involved in the care of breastfeeding women.

CONCLUSION

Poor quality of information about medicine safety during lactation can contribute to confusion in giving recommendations. This confusion can result in early cessation of breastfeeding or insufficient health care for the breastfeeding woman.

Canadian Consensus on Female Nutrition: Adolescence, Reproduction, Menopause, and Beyond

OBJECTIVES

To provide health care professionals in Canada with the basic knowledge and tools to provide nutrition guidance to women through their lifecycle.

OUTCOMES

Optimal nutrition through the female lifecycle was evaluated, with specific focus on adolescence, pre-conception, pregnancy, postpartum, menopause, and beyond. The guideline begins with an overview of guidance for all women, followed by chapters that examine the evidence and provide recommendations for the promotion of healthy nutrition and body weight at each life stage. Nutrients of special concern and other considerations unique to each life stage are discussed in each chapter.

EVIDENCE

Published literature, governmental and health agency reports, clinical practice guidelines, grey literature, and textbook sources were used in supporting the recommendations made in this document.

VALUES

The quality of evidence was rated using the criteria described in the report of the Canadian Task Force on Preventive Health Care. CHAPTER 2: GENERAL FEMALE NUTRITION: Summary Statements Recommendations CHAPTER 3: ADOLESCENCE NUTRITION: Summary Statements Recommendations CHAPTER 4: PRE-CONCEPTUAL NUTRITION: Summary Statement Recommendations CHAPTER 5: NUTRITION IN PREGNANCY: Summary Statements Recommendations CHAPTER 6: POSTPARTUM NUTRITION AND LACTATION: Summary Statements Recommendations CHAPTER 7: NUTRITION DURING MENOPAUSE AND BEYOND: Summary Statement Recommendations.

Nonnutritive Sweeteners in Breast Milk

Nonnutritive sweeteners (NNS), including saccharin, sucralose, aspartame, and acesulfame-potassium, are commonly consumed in the general population, and all except for saccharin are considered safe for use during pregnancy and lactation. Sucralose (Splenda) currently holds the majority of the NNS market share and is often combined with acesulfame-potassium in a wide variety of foods and beverages. To date, saccharin is the only NNS reported to be found in human breast milk after maternal consumption, while there is no apparent information on the other NNS. Breast milk samples were collected from 20 lactating volunteers, irrespective of their habitual NNS intake. Saccharin, sucralose, and acesulfame-potassium were present in 65% of participants' milk samples, whereas aspartame was not detected. These data indicate that NNS are frequently ingested by nursing infants, and thus prospective clinical studies are necessary to determine whether early NNS exposure via breast milk may have clinical implications.

The identifying and counseling of breastfeeding women by pharmacists

OBJECTIVE

Concerns about medications influence breastfeeding decisions. Mothers may stop breastfeeding when they take medications. After the distribution of Thomas Hale's Medications and Mother's Milk (MMM) (Hale Publishing, Amarillo, TX, 2006) by the Rhode Island Department of Health (Providence, RI) in November 2006 to Rhode Island pharmacies, we investigated, during the summer of 2007, what strategies and resources pharmacists were using to identify breastfeeding women and guide medication recommendations.

METHODS

Copies of MMM were sent to 47 pharmacies in Rhode Island. Subsequently, one pharmacist at each site completed a confidential, 10-question written survey.

RESULTS

The survey response rate was 92%. More than half (58%) of the pharmacists surveyed never asked women if they were breastfeeding. Most (85%) of pharmacists reported feeling somewhat or very comfortable giving advice to breastfeeding women. All but one pharmacist who had received MMM reported using the reference at least monthly. More than half (52%) of the pharmacists reported using the Physician's Desk Reference (Thomson PDR, Montvale, NJ).

DISCUSSION

Pharmacists need a consistent approach to identify breastfeeding women and access to reliable, continuously updated resources to guide their advice about medication use to breastfeeding women. Physicians and pharmacists should collaborate to prevent medication use from being a barrier to breastfeeding.
