Arsénico en agua de consumo

Why / when / how

Reducing exposure to arsenic in drinking water is associated with lower all-cause mortality, following a dose-response relationship. The certainty of the evidence for the critical outcomes is low. This is why the recommendation is conditional in favor, because the balance between benefits and risks is favorable, although with lower certainty.

Cautions

Before intervening on substance use and exposure to toxicants, assess the patient's consumption pattern, dependence, and clinical conditions, and individualize the approach. Discontinuing substances that produce physical dependence may require medical supervision because of the risk of a withdrawal syndrome, so it should not be stopped abruptly without assessment. Advise seeking professional care in the presence of any warning sign, including in crisis situations, and refer to specialized addiction treatment/environmental health services, according to the case. Reassess the course periodically.
