Is Kinestase Safe in Breastfeeding

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

It is excreted into breast milk in clinically non-significant amount. No problems attributable to this drug have been observed among infants whose mothers were receiving this medication. It may cause an increase of prolactin secretion. American Academy of Pediatrics states that it is a medication usually compatible with breastfeeding. Because of the high risk of QT-interval prolongation and cardiac arrhythmias in patients who are taking it, especially if other medicines are associated or patients are affected by other conditions, it has been withdrawn from the market in many countries.

Kinestase was removed from the market in the United States by the U.S. Food and Drug Administration because of cardiac toxicity. Because of the low levels of Kinestase in breastmilk, its use is acceptable in nursing mothers if it is required.
