Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
Thank you for helping to protect and promote breastfeeding.

Calcium channel blocker and antihistamine derived from piperazine with sedative effect. Used for the prophylaxis of migraines and vertigo. Oral administration in one daily dose, preferably at night due to the sedation it causes.
At the date of the last update, we found no published data on its excretion in breast milk.
Its very high binding to plasma proteins, very high volume of distribution and moderately high molecular weight make it difficult to excrete in breast milk, but its very long half-life (18 days) may facilitate excretion.
It increases prolactin levels (Formisano 1991, Cortelli 1988 and 1985, Bonuccelli 1988, Maestri 1987) and induces parkinsonism. (Teive 2004)
Until more data on this drug in relation to breastfeeding is known, safer alternatives are preferable - Propranolol, Metoprolol, Sertraline, Escitalopram, Amitrptyline or Valproate in migraine prophylaxis (Pringsheim 2012, Davanzo 2014) and Nimodipine, Betahistine or Ginkgo biloba in the prophylaxis of vertigo - especially in the neonatal period and in case of prematurity.
If this medicine is taken during breastfeeding, sleepiness and adequate feeding of the infant should be monitored and bed-sharing with the baby (co-sleeping) is not recommended. (ABM 2020 and 2008, UNICEF 2018, 2017, 2017, 2014 and 2013, Landa 2012, UNICEF 2006)
