H1 receptor antagonists are medications that block the action of histamines at the receptor sites. These medications produce sedative, antiparkinsonian, and antiemetic effects. They cause drowsiness and are often used during early labor to promote sleep and to decrease anxiety. Phenothiazines specifically cross the placenta readily and may produce decreased fetal heart rate beat-to-beat variability.
