title: Therapeutic choices for nausea and vomiting of pregnancy: a critical review of a systematic review.
abstract: With 80% of pregnant women suffering from some degree of "morning sickness," or nausea and vomiting of pregnancy (NVP), symptom management is a major challenge. A recent Cochrane systematic review of randomized controlled trials concluded that, to date, there is no strong evidence of effectiveness for practically any therapeutic agent used for management of NVP. Because of fears of teratogenicity and litigation, RCTs are rarely conducted in pregnancy. In the absence of the best possible evidence from RCTs, well planned and executed prospective observational studies should be used as the best available evidence to guide clinical practice.
