Guanabenz has been assigned to pregnancy category C by the FDA. Some animal data have shown an increased incidence of fetal loss, neonatal mortality, and skeletal abnormalities after doses three to six times the maximum recommended human dose of 1 mg/kg were given. There are no controlled data in human pregnancy. Guanabenz should only be given during pregnancy when benefits outweighs risk.
