What do I need to know about caring for someone with mercury poisoning?

Most of the time, the effects of mercury poisoning disappear within 90 days once the person is no longer exposed. You can help by carefully eliminating any sources of mercury exposure, disposing of any contaminated items properly, providing supportive care, monitoring the person's recovery, and talking to the doctor the moment you see something unusual. Sometimes it takes time for symptoms to surface. Be on the lookout for excessive coughing, chest tightness, shortness of breath, irritability, and trouble sleeping, for example. Mercury poisoning is not contagious, so there is no danger to you.
