What is Naloxone? How does it work?

Simply put, Naloxone is a drug that treats life-threatening opioid overdoses . You may be wondering what an opioid is. These are medications that doctors mainly prescribe as painkillers . Also, some people abuse them as narcotics. For example, morphine, fentanyl, tramadol , and oxycodone fall into this category. Heroin is also an opioid.

If someone takes too much of this type of opioid, that is, an overdose, their breathing will start to slow down, and they may even stop breathing altogether. They will also become very sleepy , lose consciousness, and become so sleepy that they cannot be awakened. These are the most dangerous symptoms of an opioid overdose.

So, what does this Naloxone drug do? This drug temporarily reverses the effects of opioids by binding to certain receptors in our body's brain. It's like "blocking" the action of the opioid. That's why these Naloxone drugs are also called opioid blockers . It comes in the form of a nasal spray, so it's easy to use.

The most important thing is that after using this medicine, you must definitely seek medical help immediately. Call an ambulance (in Sri Lanka, you can call 1990) or take the person to a hospital immediately. Because the effects of Naloxone are temporary, further treatment may be required.

This drug can be found on the market under names like Kloxxado and Narcan.

What should I tell the medical team before using this medicine?

If a doctor advises you to carry a naloxone nasal spray, or if you give it to someone else, it's a good idea to be aware of some information. In particular, yourMake sure the care team is aware of these things:

  • Heart conditions: If you have any heart conditions, you should tell us about them.
  • Substance use disorder: If someone is addicted to drugs, doctors need to be aware of the condition. Because naloxone suddenly reverses the effects of opioids, some people may experience sudden withdrawal symptoms .
  • Allergies: If you have had an allergic reaction to Naloxone, other medications, foods, dyes, or preservatives, it is imperative that you tell your doctor.
  • Pregnancy or trying to get pregnant: Tell your doctor if you are pregnant or planning to become pregnant.
  • Breastfeeding: If you are a breastfeeding mother, inform the doctor about this as well.

This information is important because it allows doctors to be aware of the possible side effects of using Naloxone in advance and provide the necessary advice.

How do you use this nasal spray correctly?

This is a medicine used for the nose. It is very important to know how to use it properly and not panic in an emergency.

2. Head and neck: Place one of your hands under his neck and tilt his head back slightly. This will open up his nostrils.

3. Give the nasal spray: Insert the nozzle of the nasal spray into one nostril and activate the spray fully (press the plunger). One spray per nostril.
