Final answer:
An Epipen is used to treat severe allergic reactions by injecting epinephrine, while Narcan is an opioid-overdose antidote used to reverse the effects of opioids.
Step-by-step explanation:
The difference between Narcan and an Epipen is that they are used to treat different conditions.
An Epipen is used to treat severe allergic reactions, such as anaphylaxis, by injecting epinephrine. This helps counteract the drop in blood pressure and stop life-threatening symptoms. It is commonly prescribed for individuals with severe allergies.
Narcan, on the other hand, is an opioid-overdose antidote. It is used to reverse the effects of opioids and help a person wake up and breathe until emergency medical treatment can be provided. Narcan is commonly distributed and used for cases of opioid overdose.
