How do you administer Narcan naloxone?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information. Talk with your patients and their family, friends, and caregivers about the benefits of naloxone. In March 2023, the FDA approved an Rx-to-OTC switch for Narcan 4 mg Nasal Spray for over-the-counter (OTC), nonprescription use. The FDA’s action now allows Narcan to be sold directly to consumers at drug stores, convenience stores, grocery stores, gas stations, and online.

Table II.

1. The continued PLGA degradation and increased osmotic pressure eventually ruptured the membrane (27–29), as observed around Day 21.
2. Fully review directions enclosed in the box when you receive the medication; do not wait until an overdose situation occurs.
3. This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
4. Naloxone is being used more by police officers, emergency medical technicians, and non-emergency first responders than before.
5. Also available to the naloxone arsenal is a naloxone auto-injector product called EVZIO®.

Similar to the naloxone-PLGA microparticles, the PLGA microparticles were tested using in vitro drug release test conditions. The samples from Days 1 and 4 were tested in a dilution series to investigate their effects on β-arrestin 2 recruitment. Naloxone-PLGA microparticles were made with four different theoretical drug loading percentages (T-DL%) (30%, 40%, 50%, and 60%) for each of the two PLGAs. T-DL was defined as the weight of naloxone divided by the total weight of the naloxone and PLGA in the initial oil phase formulations.

On Day 2, the microparticles exhibited irregular shapes with crater-like pores, and many of them appeared as deflated balls (30). The microparticles swelled to large sizes at Day 4 and degraded and disintegrated at Day 10. Formulation B75-L had a smooth surface at Day 2, and the continued swelling resulted in the shallow wrinkled surface at Day 4 and large crater-like holes sine Days 10. The microparticles started to collapse on Day 21 due to swelling-shrinking, thermal expansion, and mechanical stress (26, 31). Formulation D50-L has about 50% (48.5% w/w) naloxone loading, and the drug release was faster than other formulations with lower drug loading. The swelling was not as pronounced as Formulation B50-L, probably due to the faster release of naloxone and other components from the microparticles.

An in vivo rodent model of neuropathic pain showed that the Nal-cNPs could block the effects of high dose (10 mg/kg) acute morphine for up to 4 days. PLA degrades very slowly, resulting in the long lifetime of the polymer in the body (21, 22). In this study, naloxone base was used to prepare PLGA microparticles by an O/W solvent extraction approach.

The number of drug overdose deaths in 2019 was 70,630, and over 70% of them involved an opioid (2). This is mainly due to the increased use of synthetic opioids, such as tramadol and fentanyl, either prescribed or illicitly obtained (1). In 2020, the COVID-19 pandemic disrupted the daily life of all people in the United States. The total drug overdose deaths jumped to over 85,000 in the 12 months ending in August 2020, which shows a 20% increase in drug overdose deaths than in 2019.

Stop Overdose

They should be monitored for another 2 hours after the last dose of naloxone is given to make sure breathing does not slow or stop. Contact your local health department to learn about community programs that may provide naloxone for free or for a reduced cost. Talk to your doctor or pharmacist if you or someone you know is taking prescribed opioids or using illegal opioids.

It can restore normal breathing within 2 to 3 minutes in a person whose breath has slowed, or even stopped, as a result of opioid overdose. Naloxone injection is used along with emergency medical treatment to reverse the life-threatening effects of a known or suspected opiate (narcotic) overdose. Naloxone injection is also used after surgery to reverse the effects of opiates given during surgery. Naloxone injection is given to newborns to decrease the effects of opiates received by the pregnant mother prior to delivery.

Drug information

Patients without insurance can check the retail costs at their local pharmacies. Some drug companies have cost assistance programs for patients unable to pay for it. Naloxone injection may not reverse the effects of certain opiates such as buprenorphine (Belbuca, Buprenex, Butrans) and pentazocine and may require additional naloxone doses. The Stop Overdose website educates drug users on fentanyl, naloxone, polysubstance use, and dealing with stigma.

Drug addiction is a chronic disease characterized by compulsive, or uncontrollable, drug seeking and use despite harmful consequences and long-lasting changes in the brain. The changes can result in harmful behaviors by those who misuse drugs, whether prescription or illicit drugs. Families with loved ones who struggle with opioid addiction should have naloxone nearby; ask their family member to carry it; and let friends know where it is. The cost of naloxone varies depending on where and how you get it, as well as your health insurance. People with insurance can check with their insurance company to see what the cost is, while individuals without insurance can check with their local pharmacies.

Its administration may result in acute opioid withdrawal (agitation, nausea, vomiting, diarrhea, “goose flesh”, tearing, runny nose, and yawning). When victims experience these symptoms, they may become irritable and anxious. It is uncommon, however, for the revived victim to become violent or combative.

Naloxone can be given safely to people of all ages, from infants to older adults. This includes an adolescent or young adult who may have unintentionally taken an opioid. Naloxone will not harm someone if you give it to them and they are not overdosing on an opioid.
