Diclegis contains two active ingredients: doxylamine succinate and pyridoxine hydrochloride [1]. Doxylamine succinate is an antihistamine, and pyridoxine hydrochloride is a form of vitamin B6 [1].
What is the mechanism of action for Diclegis?
Doxylamine succinate works by blocking the action of histamine, a substance in the body that can trigger nausea and vomiting. Pyridoxine hydrochloride, or vitamin B6, is believed to help reduce nausea through its role in metabolic processes [1].
How does Diclegis work to relieve nausea and vomiting?
The combination of doxylamine succinate and pyridoxine hydrochloride in Diclegis is specifically formulated to address nausea and vomiting experienced during pregnancy [1]. The antihistamine properties of doxylamine succinate counter the effects that can lead to queasiness, while pyridoxine hydrochloride supports metabolic functions that may also influence these symptoms [1].
