Natroba and Breastfeeding
The full risks of breastfeeding while using Natroba (spinosad) are unknown, since no studies have been done on this topic. However, the active ingredient in Natroba is not expected to pass through breast milk in significant amounts. If you are nursing, talk to your doctor to see if this medication is your best option for lice treatment.
At this time, it is unknown if Natroba® (spinosad) passes through breast milk. Therefore, if you are breastfeeding a child, you should talk with your healthcare provider about using Natroba.
No research has been done to see if Natroba passes through breast milk in humans. It is important to understand that the active ingredient (spinosad) is not absorbed into the bloodstream in any significant amount, and would therefore not pass through breast milk in any significant amount.
However, Natroba contains benzyl alcohol as an inactive ingredient. When given by injection, benzyl alcohol is known to be dangerous to newborns, particularly premature newborns. Therefore, there is at least a theoretical risk that this medication could cause problems in a newborn, especially a premature newborn, if used by a breastfeeding mother. To eliminate this potential risk, the woman could "pump and dump" for eight hours after using Natroba.
You should discuss breastfeeding and Natroba with your healthcare provider. 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, the two of you can make a shared decision that is right for you.
