Narcan

Narcan (also known as Naloxone) is a medication used to counter the effects of opioid overdose, specifically to counteract life-threatening depression of the central nervous system and respiratory system. It is commonly used in emergency situations to block or reverse the effects of opioids.

Uses

Narcan is primarily used in emergency cases of opioid overdose, such as heroin and morphine. It works by blocking the effects of opioids, particularly the life-threatening effects on the respiratory and central nervous system. It is also used for diagnosis of suspected or known acute opioid overdose and for blood pressure support in septic shock.

Administration

Narcan can be administered intravenously, intramuscularly, or as a nasal spray. The medication begins to take effect within two minutes when injected and within five minutes when given as a nasal spray.

Side Effects

Common side effects of Narcan include agitation, palpitations, and sweating. More serious side effects may include pulmonary edema, cardiac arrest, and severe allergic reactions.

Availability

In many countries, Narcan is available without a prescription. In the United States, it is classified as a prescription drug, but is available without a prescription in many states.
