Oral administration in a daily dose for 8 to 16 weeks.

Since the last update we have not found any published data on its excretion in breast milk.

Its pharmacokinetic characteristics (lelevated molecular weight and very high plasma protein binding: EMA 2019, AEMPS 2019, Smolders 2019) make it very unlikely its excretion into breast milk in significant amounts

Possible side effects are rare and mild.
