We collected self\u2010reported data about NVP and use of commonly reported pharmacological and herbal\/natural treatments (ondansetron, promethazine, pyridoxine, metoclopramide, doxylamine succinate, ginger, phosphorated carbohydrate solution, and prochlorperazine) from mothers of non\u2010malformed control infants.

Specific treatment use varied after adjustment for study centre (ondansetron: 3.4%; promethazine: 4.2%; pyridoxine: 3.2%; metoclopramide: 0.7%; doxylamine succinate: 1.7%; ginger: 1.0%; phosphorated carbohydrate solution: 0.4%; and prochlorperazine: 0.3%). Treatment use increased for each agent over the study period. Women with more years of education reported more NVP and treatment use. White (72%), Hispanic (71%), and other race (73%) women reported more NVP than Black women (67%); White women used selected NVP treatments most frequently, and Black women used them more than Hispanic women. Though women aged 25\u201034\u00a0years reported more NVP (72%) than younger (69%) or older (67%) women, the frequency of medication use was similar among women aged 25\u201034 and \u226535, and lower among women aged &lt;25\u00a0years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>National Birth Defects Prevention Study controls reported NVP at frequencies similar to those previously reported.
