Fentanyl is a powerful opioid that has become a major concern in recent years. It’s much stronger than other opioids like morphine, making it dangerous even in small amounts.
According to the CDC1, synthetic opioids like fentanyl were responsible for nearly 70% of opioid overdose deaths in the U.S. This rise in fentanyl-related deaths highlights the importance of understanding how long it stays in the body and recognizing the signs of its use.
Understanding Fentanyl and Its Dangers
Fentanyl is used medically for severe pain, but it’s also a leading cause of overdose deaths when used illegally. It’s 50 to 100 times more potent than morphine2, meaning even a tiny amount can lead to overdose. Because of its strength, fentanyl has played a significant role in the opioid crisis, contributing to the growing number of overdose deaths.
Fentanyl Metabolism and Half-Life
When fentanyl enters the body, the liver breaks it down into substances that are eventually removed through urine. The half-life of fentanyl, or the time it takes for half of the drug to leave your system, ranges from 3 to 12 hours.
How long fentanyl stays in the body depends on factors like the individual’s health, how much they take, and how often they use it. People with liver or kidney problems may find that fentanyl takes longer to leave their system.
How Long Does Fentanyl Stay in Urine, Blood, and Other Tests?
Fentanyl detection times vary. It depends on the type of drug test used, as different tests have different sensitivities and detection windows. Here’s a closer look at how long fentanyl can be detected in various tests:
- Urine Tests: Fentanyl can be found in urine for 1 to 4 days after use. This time can vary based on how often and how much the person uses, as well as their metabolism. For chronic users, it might stay in the urine even longer.
- Blood Tests: Blood tests offer a shorter detection window, usually identifying fentanyl for up to 12 hours after use. These tests are often used in emergencies to check for recent drug use but are not the best option for detecting long-term use.
- Saliva Tests: Like urine tests, saliva tests can detect fentanyl for about 1 to 4 days after the last use. These tests are quick and non-invasive, making them a popular choice for roadside testing or workplace screenings.
- Hair Tests: Fentanyl can be detected in hair for up to 90 days, which helps in identifying long-term use. However, this method isn’t good for detecting recent drug use since it takes time for the drug to show up in hair.
Besides these standard testing methods, fentanyl testing strips have become an important tool in preventing overdoses. These strips allow individuals to test drugs for the presence of fentanyl before use.
Since fentanyl is often mixed with other substances without the user’s knowledge, these strips can help reduce the risk of accidental overdoses. This is especially true in communities where opioid use is prevalent. While testing strips are not a replacement for professional testing, they offer an additional layer of safety for those at risk.
Signs of Fentanyl Use and Overdose Symptoms
Recognizing the signs of fentanyl use can help you take action early. Physical signs include drowsiness, confusion, and small pupils. Behavioral signs may include withdrawing from social activities and neglecting responsibilities.
Fentanyl overdose symptoms are severe and require immediate medical help. If you see someone showing these signs, call emergency services immediately. These symptoms include:
- Slow or stopped breathing
- Extreme drowsiness
- Loss of consciousness
Fentanyl Withdrawal: Symptoms and Timeline
Fentanyl withdrawal symptoms can be tough to handle and may start within a few hours of the last dose. Early symptoms include anxiety, muscle aches, and sweating. As withdrawal progresses, symptoms like nausea, vomiting, and diarrhea can occur. Withdrawal usually peaks around 2 to 3 days after the last use and can last for a week or more. In some cases, cravings and mood swings may last longer.
