- Cold and sweaty skin
- Extreme sleepiness
- Trouble breathing
Many people die from pain medicine overdoses. In fact, more people overdose from pain medicines every year than from heroin and cocaine combined.
For heroin overdoses, symptoms could include:
- Slow and shallow breathing
- Blue lips and fingernails
- Clammy skin
- Possible death
In addition, because heroin abusers do not know the actual strength of the drug or its true contents, they are at a high risk of overdose or death.
And for the synthetic opioid fentanyl, the overdose symptoms could include:
- Changes in pupillary size
- Cold and clammy skin
- Respiratory failure leading to death
The presence of a triad of symptoms such as coma, pinpoint pupils, and respiratory depression are strongly suggestive of opioid poisoning.
