How Long Does Fentanyl Stay In Your System?

Table of Contents

Fentanyl, a highly potent opioid, is known for its rapid absorption into the bloodstream following ingestion, inhalation, or injection. Once in the bloodstream, it travels to various organs and tissues, including the brain. Here, it binds to opioid receptors, producing significant pain relief and feelings of euphoria.

Factors Influencing Fentanyl’s Presence in the Body

The duration of fentanyl in the system varies based on several factors:

  • Dosage: Higher doses of fentanyl take longer to be eliminated from the body.
  • Route of Administration: The method of fentanyl use (smoking, injecting, swallowing) affects its absorption and elimination rates.
  • Frequency of Use: Regular or chronic use can lead to accumulation in the body, prolonging elimination time.
  • Individual Factors: Age, weight, metabolism, liver and kidney function, and overall health all influence how long fentanyl stays in the system.

Fentanyl Drug Tests: Detection Windows

The detection window for fentanyl varies depending on the type of drug test:

How long does fentanyl stay in the urine?

Urine tests, the most common for fentanyl, can detect the drug and its metabolites for 2-4 days after last use. Detection time is influenced by the drug amount, usage frequency, and individual metabolism.

How long does fentanyl stay in the blood?

Blood tests can detect fentanyl for up to 12 hours post-use. Though less common, they offer accurate results and are used in emergencies or forensic settings.

How long does fentanyl stay in the Saliva?

Saliva tests can detect fentanyl for 1-2 days after the last use. They are non-invasive and easy to administer.

How long does fentanyl stay in the hair?

Hair tests, the most sensitive, can detect fentanyl use for up to 90 days post-use. They provide a comprehensive drug use history but are more costly and time-consuming.

Fentanyl Half-Life

The half-life of fentanyl, the time taken for half of the drug to be eliminated from the body, ranges from 3 to 12 hours. This means it could take up to 32 hours (or roughly five half-lives) for a fentanyl lozenge to be eliminated from the body. The half-life varies based on the dosage form:

fentanyl half life

Form Half-Life
Lozenge 3.2 to 6.4 hours
Intrabuccal tablet 2.6 to 11.7 hours
Sublingual tablet 5 to 13.5 hours
Sublingual spray 5.3 to 12 hours
Nasal spray 15 to 25 hours
Transdermal patch 20 to 27 hours

A longer half-life means prolonged effects and an increased risk of side effects and overdose.
