Tasmar and Breastfeeding
At this time, it is unclear if Tasmar (tolcapone) is safe for women who are breastfeeding. Tasmar has been shown to pass through breast milk in rats, and it is likely to also pass through breast milk in humans. Theoretically, the drug can affect certain hormones, which may affect a woman's ability to breastfeed. Before taking Tasmar while breastfeeding, talk to your healthcare provider.
Tasmar and Breastfeeding: An OverviewIt is not known if Tasmar® (tolcapone) passes through breast milk in humans or if it is safe for use during breastfeeding. Therefore, you should talk with your healthcare provider before taking the drug if you are breastfeeding or plan to start.
Can I Take Tasmar While Breastfeeding?Studies have shown that tolcapone passes through breast milk in rats, although it is unknown if the same is true for humans. However, based on the chemical properties of Tasmar, it is predicted that the drug will pass through breast milk in humans. Because Tasmar can cause fatal liver failure, many healthcare providers are not comfortable recommending this medication for women who are breastfeeding.
It should be noted that Tasmar is always used in combination with two other Parkinson's medications: carbidopa and levodopa. Studies have shown that levodopa passes through breast milk in humans. It can also decrease the level of prolactin in the mother, a hormone that is important for breastfeeding. Theoretically, levodopa may negatively affect a woman's ability to successfully breastfeed.
