Is Sofosbuvir Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Sofosbuvir? Is Sofosbuvir safe for nursing mother and child? Does Sofosbuvir extracts into breast milk? Does Sofosbuvir has any long term or short term side effects on infants? Can Sofosbuvir influence milk supply or can Sofosbuvir decrease milk supply in lactating mothers?

Usually used in combination with Ledispavir in the treatment of hepatitis C. Since the last update we have not found published data on its excretion in breast milk. Its pharmacokinetic data (moderately elevated molecular weight, good percentage of protein binding and very short half-life) impedes its passage to breast milk in significant amounts, so although there is disagreement (Thompson 2016), some authors consider that treatment with sofosbuvir, alone or in combination with ledipasvir is not contraindicated during breastfeeding (Spera 2016).

Sofosbuvir has not been studied in nursing mothers being treated for hepatitis C infection. If sofosbuvir alone or in combination with ledipasvir (Harvoni) is required by the mother, it is not a reason to discontinue breastfeeding.[1] Some sources recommend against breastfeeding when sofosbuvir is used with ribavirin. Hepatitis C is not transmitted through breastmilk[2][3] and breastmilk has been shown to inactivate hepatitis C virus (HCV).[4][5] However, the Centers for Disease Control recommends that mothers with HCV infection should consider abstaining from breastfeeding if their nipples are cracked or bleeding. It is not clear if this warning would apply to mothers who are being treated for hepatitis C. Infants born to mothers with HCV infection should be tested for HCV infection; because maternal antibody is present for the first 18 months of life and before the infant mounts an immunologic response, nucleic acid testing is recommended.[2][3]
