A study on morning sickness has been done by Cochrane researchers at the Dublin City University in Ireland. The researchers did a methodical review of therapies done in nausea, morning sickness, and other pregnancy related symptoms. They found that the therapies were not ‘safe and effective’.

For the study, as many as 4,041 pregnant women were taken. A total of 27 trials were done for around 20 weeks. In these women, level of nausea was recorded using the treatments like acupuncture, use of ginger, intake of vitamin B6, and anti-vomiting medicines.

According to Professor Anne Matthews at the School of Nursing at Dublin City University, the treatments showed some kind of relief in these women, but overall results were not that consistent. So it is very difficult to reach some kind of definite conclusion regarding any single therapy.

The Professor further said that not much information is available about the effectiveness of these treatments and whether these therapies actually bring any changes in the lifestyle of the women.

The scientists also mention that it is not very clear whether anti-histamines and anti-vomiting drugs are really effective to use.

It is worth noting that Debendox drug has been banned in the United Kingdom, but is regularly prescribed in Canada.
