What is naloxone and how does it work?

Last Updated: 15th January, 2020

Naloxone is a drug that temporarily counteracts opioid overdose. Naloxone only works to temporarily prevent opioid drugs from binding to the brain, so if a person uses narcotics in combination with other drugs, such as alcohol or benzodiazepines, the overdose will be more difficult to reverse.

Consequently, how is naloxone used?

Narcan (naloxone) is an opioid antagonist used for the complete or partial reversal of opioid overdose, including respiratory depression. Narcan is also used for diagnosis of suspected or known acute opioid overdose and also for blood pressure support in septic shock.

Additionally, is narcan used for anything other than overdose? Naloxone, sold under the brand name Narcan among others, is a medication used to block the effects of opioids. It is commonly used for decreased breathing in opioid overdose. Naloxone may also be combined with an opioid (in the same pill) to decrease the risk of opioid misuse.

In this manner, how does naloxone affect the body?

Naloxone works by knocking the opioids out of the receptors in the brain where they are having their effect, and blocking them from returning. Naloxone can be sprayed into the nose or injected into a muscle. This reverses all of the effects of the opioids taken.

What happens if you give Narcan to someone who doesn't need it?

You can't harm a patient “It's not going to harm anyone that doesn't need it. It's only going to reduce the effect of an opioid overdose. It will never make it worse.” The reluctance to dispense the drug could cost a person their life, according to Dr.
