Recent research from the US suggests that Viagra, the anti-inpotence drug, can stop working for many patients after a few years. The scientists, from the university of Alabama, followed up 151 men who began using the drug in 1997. For most of the men the drug worked initially, but 3 years later, by 2000, it had stopped working for about a third of the men who were still using it. In most cases it took between one and eighteen months to stop working. (BMJ 8/9/01)
