Tranquilizer of the central nervous system with antipsychotic, anxiolytic and antiemetic properties.
Oral or intramuscular administration 1 to 3 times a day.
It is excreted in breast milk in amounts from undetectable to very small (Zuppa 2010, Yoshida 1998, Ohkubo 1993, Wiles 1978, Uhlir 1973) even after maternal doses of 1200 mg (Blacker 1962).
Urine levels of two infants whose mothers were taking chlorpromazine were very low, in the order of 1 microgram / L (Yoshida 1998).
It has been described in infants of mothers taking chlorpromazine from no side effects (Wiles 1978, Ayd 1964, Kris 1957) with normal growth and neurological development (Lacey 1971, Kris 1962) to numbness and sedation (Lee 1993, Wiles 1978, Lacey 1971 ) with a decrease in developmental score at 12 and 18 months when they were taking other psychotropic drugs at the same time (Yoshida 1998)
Supervision of drowsiness and development in infants is required (Klinger 2013, WHO 2002) and prescribed at the lowest effective dose and, if possible, in monotherapy (Parikh 2014, Tényi 2000).
Dosage of 100 mg per day does not cause problems for the infant (Lawrence 2016 p394).
Because it is a dopamine inhibitor, it produces an increase in prolactin levels and can increase milk production, having been used as a galactogogue (Lawrence 2016 p670, Mannion 2012, Muresan 2011, Zuppa 2010, Gabay 2002).
