HC Deb 22 July 1980 vol 989 c216W
Mr. Ashley

asked the Secretary of State for Social Services what information he has about the percentage of pregnant patients who have sufficiently severe nausea and vomiting to necessitate antiemetic drug therapy.

Dr. Yaughan

No statistical information is available centrally. The need for such therapy in each individual case is a matter for clinical decision by the doctor concerned.
