14 A, B, C, D, X – NOT hierarchical Human data are lacking or inadequate for drugs in the B1, B2 and B3 categories Subcategorisation of the B category is based on animal data The allocation of a B category does not imply greater safety than a C category Medicines in category D are not absolutely contraindicated during pregnancy (e.g.anticonvulsants)

15 Case 5: Post partum Nikki, with 3 day old Arthur calls from home NVD, early discharge Increasing “period pain” feeling hot and cold, moderate PV bleeding, light headed and tired Midwife already visited for the day Issues for GP: – ?how urgent – How to fit in to schedule – Who to call and how if concerned
