It is a tertiary amine with antimuscarinic-anticholinergic properties, levo isomer of atropine, twice as potent as atropine. It is found in plants of the nightshade family such as henbane, mandrake, angel's trumpets, jimson weed, scopolia, tomato, witch tree, and belladona. It has antespasmodic action and is used to treat gastrointestinal functional disorders, biliary and renal colic, and acute rhinitis. Oral administration in 2 to 4 daily doses.
At the date of the last update we did not find any published data on its excretion in breast milk.
Although antimuscarinics can decrease prolactin production (Müller 1983, Masala 1982), once lactation is established, milk production depends more on the repeated stimulation of suckling than on prolactin levels.
Its side effects are dry mucous membranes, constipation, dilated pupils, blurred vision and urinary retention.
Given its short elimination half-life, occasional use may be compatible with breastfeeding.
