Reducing access to highly dangerous means of suicide is recognised to be an excellent way to reduce deaths. Commonly used pptions include restricting access to guns, knives, bridges and other open high areas, dispensing only small quantities of pharmaceuticals, and banning and removing highly hazardous pesticides from agricultural practice through legislation and import limitations.
Other measures to reduce suicide include responsible reporting of suicide in the media, such as avoiding language that sensationalizes suicide and avoiding explicit description of methods used, and early identification and management of mental and substance use disorders. Follow-up care by health workers through regular contact, including by phone or home visits, for people who have attempted suicide, together with provision of community support, can also be effective.
