Which medication is commonly used to reverse the effects of opioids such as fentanyl?

Naloxone is the medication commonly used to reverse the effects of opioids such as fentanyl. It works as an opioid antagonist, meaning it binds to the same receptors in the brain that opioids do, effectively blocking their effects. When administered during an opioid overdose, naloxone can quickly restore normal respiration and consciousness, making it a crucial tool in emergency situations. Its effectiveness and ability to be administered nasally or by injection have made it widely accessible as a life-saving treatment for opioid overdoses.

The other medications listed do not have the same effect on opioid overdoses. Ibuprofen and acetaminophen are pain relief medications with no impact on opioid receptors. Adrenaline, or epinephrine, is typically used in situations such as severe allergic reactions or cardiac arrest, but it does not reverse the central nervous system effects of opioids. Thus, naloxone stands out as the correct choice for reversing opioid effects.
