Phentermine has not been studied in any breastfeeding women, and it is not known if phentermine passes through breast milk. However, phentermine is chemically similar to amphetamines, which are known to pass through breast milk (and to have negative effects on breastfed infants).
Phentermine has the potential to cause hyperactivity, restlessness, and potentially serious side effects if passed to a nursing child through breast milk. Also, it is important to remember that breastfeeding is usually a time of increased caloric need for mothers, not a time to be dieting. It is important to eat an adequate and well-balanced diet while breastfeeding. Because phentermine offers little benefits to a breastfeeding woman, and may cause harm in a nursing child, it is generally recommended that breastfeeding women not take phentermine.
You should talk with your healthcare provider about phentermine and breastfeeding. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, you and your healthcare provider can make a shared decision about phentermine and breastfeeding in your particular situation.
