Hi, Thanks for the query. Novidoxine contains meclozine and pyridoxine. It belongs to category B drugs in pregnancy. Means according to animal studies no adverse effects on the fetus reported but sufficient human studies are lacking. So you can use the tablet with your doctor s advice. Once your nausea subsides you can stop the drug. Other alternatives are drug containing doxinate etc. General measures like: -Decreasing oil and fat content in the meals -Taking small quantities at frequent intervals -Including fruits, vegetables, milk in meals etc can help to some extent. Take care.
