Whether your loved one is currently seeking help or not, knowing how to identify an overdose could save a life and prevent further tragedy. The most common signs of this frightening response are:

1. Irregular vital signs, such as increased, decreased, or absent pulse, respiratory rate, and blood pressure
2. Cool and sweaty or hot and dry skin
3. Sleepiness, confusion, or even coma
4. Chest pain due to lung or heart damage and/or shortness of breath
5. Organ damage, depending on the specific drug used
6. Vomiting, nausea, abdominal cramps, or diarrhea, as well as vomiting blood or bloody bowel movements (although these are rarer)

An overdose affects the entire body and can come on quickly, so swift action on your part can make all the difference. If you suspect someone is experiencing this life-threatening reaction, call 911 right away and turn the individual on their side to avoid choking on their vomit.
