Recommendations in 2 articles published in Canadian Family Physician, “Nausea and vomiting of pregnancy. Evidence-based treatment algorithm”1 and “Treatment of nausea and vomiting in pregnancy. An updated algorithm,”2 have subsequently come under critical scrutiny.3,4 These articles were not subjected to standard peer review, and Canadian Family Physician acknowledges that upon closer inspection these articles did not provide satisfactory evidence that would have justified the recommendation of doxylamine-pyridoxine as a sole first-line treatment for nausea and vomiting in pregnancy (NVP). More recent Canadian NVP guidelines have been published5; however, a subsequent re-analysis6 questions the conclusions of 1 of the studies7 cited in these guidelines to justify doxylamine-pyridoxine as a recommended first-line treatment for NVP. Additionally, for the articles in Canadian Family Physician1,2 there was an undisclosed conflict of interest with Duchesnay, the manufacturer of Diclectin, the combination of doxylamine-pyridoxine. Canadian Family Physician encourages readers to interpret previously published NVP recommendations with caution. Readers are also referred to the commentary “Motherisk and Canadian Family Physician” in the January 2017 issue of Canadian Family Physician.8
