You probably have heard the name Fentanyl if you have been watching the news or been active on social media. What originally started as a powerful prescribed painkiller is now is the center of a global overdose crisis. Now you may want to ask “Why is Fentanyl so dangerous?” Well it does have a legitimate medical use but it’s extreme potency and it’s tendency to be misused badly are what make it so dangerous. Understanding why Fentanyl is so dangerous can help you make wiser decisions around it. In this article we will try to understand just that. But before we go any further let’s first understand what Fentanyl is.
What Is Fentanyl?
Fentanyl is a very powerful lab-made synthetic opioid drug. It is approved to be used medically as a severe painkiller. It binds to a protein called mu-opioid receptors in your CNS and because it is highly fat-soluble it crosses the blood-brain barrier much faster than other opioid painkillers. That is exactly why it’s effects are so rapid and intense. That being said, it isn’t a drug that you can take for any kind of pain. Fentanyl is only prescribed to people suffering from the pain that comes from cancer treatment or post-surgical pain. It is about 50 to 100 times more potent in comparison to morphine. We are talking about pharmaceutical Fentanyl here and then there is IMF (Illicitly Manufactured Fentanyl). Fentanyl can affect your brain and body in many dangerous ways.
Why Is Fentanyl So Dangerous?
Extreme potency
Fentanyl is so dangerous because of its immense strength. Even if you take a dose as small as 2 milligrams it can still be lethal and because of this it is one of the most potent opioids available on the market. It is 100 times stronger than morphine and far stronger than drugs like heroin. Because of this you can very easily overdose without even knowing you have taken so much already. The margin between a medical dosage and a lethal dose is very narrow.
Fast Action
Fentanyl starts acting very quickly once it enters your body. The speed at which it acts in your body depends on the way you take it. It can start its effects within a few seconds and this makes it difficult to react if you feel adverse effects after taking it. It affects your body so fast that it doesn’t even give you enough time to ask for help. In many cases when an individual has overdosed on Fentanyl, they go unconscious within a few moments before they can respond or alert someone. This is why the fatality rate is so high when it comes to Fentanyl.
Respiratory depression
Like any other opioid Fentanyl also affects your breathing by suppressing the brain’s activity to regulate breathing. But in the case of Fentanyl due to its potency, the suppression occurs more severely. In high dosage it can completely stop your breathing which cuts off the oxygen supply to the brain. In extreme cases this can cause brain damage or Death. So if you were thinking “Can fentanyl cause death?” then yes, it definitely can kill you. In fact, it has been seen that since 2021, there have been 70,000 Fentanyl deaths per year.
Accidental overdose
With Fentanyl the risk of accidental overdose is also on the high because drug dealers often mix Fentanyl with other drugs like cocaine and heroin. They also make fake prescription pills out of Fentanyl. This can be very dangerous because you will be consuming Fentanyl without even knowing you are taking it. This increases the risk of overdose by a big hike. Consuming something as deadly as fentanyl thinking you just took some Xanax pills can be scary and very dangerous at the same time.
High addiction potential
Fentanyl affects your brain’s reward system by triggering the release of endorphins. This blocks your pain receptors and makes your brain overflow with the feeling of reward. Your brain starts feeling pleasure and becomes deeply relaxed. If you keep using it for sometime then your brain gets dependent on the drug to function normally. This can quickly escalate to both physical and psychological dependence. This will make it almost impossible to stop using without facing withdrawal effects. If dependence develops then your tolerance will increase too. Which means you will be tempted to take a higher dosage. An overdose becomes very likely in such cases.
Signs Of Fentanyl Overdose
Recognizing signs and symptoms of a Fentanyl overdose is very crucial in order to get proper medical assistance in time. Some common symptoms of Fentanyl poisoning are:
- Cold and clammy skin
- Unconsiousness
- Very slow or stopped breathing
- Purple or blue colored finger nails and lips
- Vomiting
- Seizures
- Coma-like state
- Limp body
People ask Fentanyl overdose is painful or not. Well there aren’t any symptoms that will make you feel pain as Fentanyl itself is a pain killer and doesn’t let you feel any pain. But no pain doesn’t exactly mean no suffering either. If you see someone with any of these conditions then rushing them to the nearest hospital as fast as possible is by far the best thing you can do. A delay in response can lead to brain damage that is irreversible and in the worst case, death due to lack of oxygen.
Prevention And Safety Measures
You won’t ever be prescribed to take Fentanyl by a doctor unless you are dealing with severe pain like post-surgical pain and cancer treatment pain. If you are not dealing with anything like that, then you have no reason to take Fentanyl in the first place. Fentanyl is mostly found in illicit drugs so you need to avoid illicit drugs altogether. Other than that, being aware and educated about the use and misuse of such opioid drugs is very important. As a safety measure you should have Naloxone in your house. It is a life-saving medication that can reverse an opioid overdose. Taking Naloxone at the earliest sign of a Fentanyl overdose can save lives.
Final Thoughts
Fentanyl is dangerous because of more than one factor. It is extremely potent, starts its effects super fast and has a very high chance of forming addiction. It is also dangerous because it holds a risk of accidental overdose and can be pretty life-threatening. There isn’t much room for error in the case of Fentanyl. If you are suffering from a fentanyl addiction, then it can be very rough but as long as you haven’t overdosed on it, you can quit the addiction with a little help from Fentanyl addiction treatment.
