There is no convincing evidence that peripheral vasodilators produce any significant improvement in exercise tolerance in patients with peripheral vascular disease, and these drugs may do more harm than good. In the treatment of severe Raynaud's syndrome, however, thymoxamine, prazosin or nifedipine is recommended. A descriptive study was carried out, firstly, to determine why these drugs are prescribed in general practice, and secondly, to describe the drug choices in the treatment of both Raynaud's syndrome and peripheral vascular disease in a representative sample of 22 practices in Northern Ireland. Of those patients prescribed peripheral vasodilators 69·6% were diagnosed as peripheral vascular disease, claudication or atherosclerosis. Over three‐quarters of peripheral vasodilators prescribed were repeat prescriptions. Of those with Raynaud's syndrome only half were treated appropriately, and certainty of diagnosis did not guarantee appropriate treatment. Peripheral vasodilators accounted for the majority (51·5%) of items prescribed for peripheral vascular disease. A minority of patients with peripheral vascular disease (20·3%) were prescribed aspirin, and a smaller minority (4·4%) had undergone amputation. Peripheral vasodilators were prescribed unnecessarily and inappropriately. Measures to promote evidence‐based treatment of both Raynaud's syndrome and peripheral vascular disease in general practice need to be taken. © 1998 John Wiley & Sons, Ltd.
