To ask the Secretary of State for Health how many reports of suspected adverse reactions associated with Lariam were reported to the Medicines Control Agency in each year from 1990 to 1997. [15456]

Ms. Jowell

The numbers of suspected adverse reactions reported to the Committee on Safety of Medicines and the Medicines Control Agency from 1 January 1990 to 31 December 1997 for mefloquine (brand name, Lariam) as the suspect drug in the United Kingdom are given in the table:

Year Total number of suspected adverse reactions Number of reports
1990 54 19
1991 58 27
1992 52 22
1993 183 73
1994 597 227
1995 1,233 447
1996 1,361 455
1997 (up to 11 November 1997) 445 159

A report of a suspected adverse drug reaction does not necessarily mean that it was caused by the drug. Each report relates to one patient. Patients may have more than one suspected reaction and the number of reactions given exceeds the number of patients affected as seen above.
