Why Does Fentanyl Cause Bradycardia?
There are numerous dangerous side effects that can come along with the use of fentanyl. This is particularly true during instances of illicit use, or when it’s used in a way other than what’s prescribed and instructed by a physician. Fentanyl, which is a highly powerful opioid, is used in the treatment of severe, chronic pain. More specifically, it’s often used for breakthrough cancer pain.
One of the dangerous side effects of fentanyl use is bradycardia. To understand the side effects, it’s best to know what bradycardia is and also explore why fentanyl causes bradycardia in some people.
- Dizziness
- Pervasive lack of energy
- Shortness of breath
- Fainting
Along with the use of opioids like fentanyl, other causes of bradycardia can include:
- Congenital heart disease
- Heart medications
- Aging
- Scar tissue from a heart attack
- Sick sinus syndrome or sinus node dysfunction
- A heart block (the electrical impulse that travels through the heart is blocked)
When someone experiences bradycardia under most circumstances, the treatment varies depending on what’s causing it. For example, it may require certain medications or the implantation of a pacemaker. However, when fentanyl use causes bradycardia, a different solution is required.

Not only can opioids cause this disruption, but it can also happen when someone is going through withdrawal from opioids. This, among many other reasons, is why medically supervised detox is so important.
When someone experiences heart palpitations and cardiac arrhythmia without proper treatment, it can then lead to very serious and deadly circumstances including stroke, heart failure or death.
Fentanyl and opioids in general act as depressants which slow down the body’s natural systems, including the respiratory and cardiac system.
When someone uses an opioid like fentanyl chronically, it can lead to a condition called long Q-T syndrome, where the electrical conduction of the heart is slowed and the heart’s natural rhythm is disrupted. This can even happen with short-term opioid use.
When someone uses fentanyl in the long-term, this change in the natural rhythm of the heart can become permanent, contributing to a lack of adequate oxygen delivery and heart damage.
All these potential complications occur because when someone takes an opioid, it impacts the regulatory systems of their brain, as well as the heart and blood vessels.
When someone is dependent on opioids, heart palpitations and a decreased heart rate are part of the symptoms. This happens because the person’s body has become used to the presence of opioids as a way to stabilize the vital functions of their body, including their heart rate. Without the presence of an opioid, these individuals dependent on opioids often experience symptoms like palpitations and cardiac arrhythmia during withdrawal.
The fact that opioids like fentanyl can lead to complications with the heart during withdrawal is one of the reasons why a supervised detox program is so strongly recommended for people coming off these drugs.
