Nitrolingual and Breastfeeding
If you are a woman who is breastfeeding, Nitrolingual could be prescribed to treat your chest pain even though it is not known if the medication passes through breast milk. The manufacturer recommends that women who are nursing use this drug with caution and watch for possible side effects in the infant, such as headaches.
At this time, it is unknown if Nitrolingual® Pumpspray (nitroglycerin spray) passes through breast milk. Therefore, if you are breastfeeding or plan to start, you should talk with your healthcare provider before taking Nitrolingual. The manufacturer does not forbid breastfeeding women from using the drug, although it does state that the drug should be used with caution in such circumstances.
No research has been done to see if Nitrolingual passes through breast milk. Most likely, this lack of research reflects the fact that this medication is approved to treat chest pain (angina) due to coronary artery disease, a condition that is quite rare in young women.
Based on the known actions and side effects of Nitrolingual, if the drug does pass through breast milk, it is reasonable to expect that it could cause low blood pressure (hypotension) and headaches in the infant.
You should discuss Nitrolingual and breastfeeding 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.
