Biochem/physiol Actions

H1 histamine receptor antagonist; hypnotic.Doxylamine suppresses histamine at the H1 receptor. It is associated with the short term management of insomnia and temporary relief of common cold symptoms. On the other hand, doxylamine intoxication is linked with rhabdomyolysis and secondary acute renal failure.Studies in mice show that doxylamine induces liver microsomal cytochrome P450 and other enzymes involved in thyroxine (T4) metabolism. In combination with pyridoxine hydrochloride, this drug is used to treat morning sickness.
