A calcium channel blocker drug and an antihistamine piperazine derivative which has a sedative effect. Chemical structure and effects similar to Flunarizine (see specific info).Used to treat nausea and vertigo of Meniere's Disease, and symptoms of Traveler´s Sickness.It has been withdrawn from the market in several countries because of Parkinson-like symptoms. At latest update relevant published data were not found on excretion into breast milk. Its high binding capacity to plasma proteins makes it unlikely excretion into breastmilk. It should be wise on the long-term, the use of a known safer alternative until more data is available on this drug, mostly for children in the neonatal period or in case of prematurity that may be affected by an increased gut permeability. Occasional use to prevent motion sickness may be compatible with breastfeeding.

516 MD is not approved for marketing in the United States by the U.S. Food and Drug Administration, but is available in other countries. No information is available on the use of 516 MD during breastfeeding. Expert opinion recommends that 516 MD not be used in migraine prophylaxis.[1][2][3] An alternate drug is preferred, especially while nursing a newborn or preterm infant.
