Indicated in acute migraine attack.
Oral administration in a daily dose.

Since the last update we have not found published data on its excretion in breastmilk.

Several expert authors consider its use to be safe or probably safe during breastfeeding (Hale 2019, Briggs 2017, Amundsen 2015, Duong 2010).

Its use, usually in isolated doses, makes the occurrence of adverse effects in infants unlikely (Jürgens 2009).

As there is less published data than for other drugs in the same group, safer known alternatives may be preferable, especially during the neonatal period and in cases of prematurity.
