Can drug tests detect Fioricet?
Yes. Although testing for Fioricet is not common, some tests can find the drug in system, and results can show positive for barbiturates. That’s because Fioricet contains Butalbital, Acetaminophen, and Caffeine; and Butalbital is an intermediate-lasting barbiturate. For instance, an EIA test (the immunoassay technique), can detect Fioricet for up to 72 hours.
How long does Fioricet stay in system?
Fioricet can remain in a person’s system for up to 4-5 days. However, many factors affect that: overall health of the user, dosage, history of abuse, and of course, metabolism rates. Note that the half-life of Butalbital is 35 hours, of acetaminophen- 1-3 hours, and of caffeine– around 3 hours. Urine tests can detect Fioricet for up to seven days.
Fioricet, or the combination of Butalbital, acetaminophen, and caffeine, is usually used for the treatment of tension and unbearable headaches. That might sound harmless but remember that the drug can lead to severe consequences for the user. One of the potential risks is that Fioricet can show up on a drug test, which can result in job loss.
Factors That Influence the Duration & Elimination of Fioricet
Like with any other drug, many factors affect the duration and elimination of Fioricet stay in system.
- Dosage and history of abuse
- Individual factors (weight, age, overall health)
- Metabolism rates
- Lifestyle (activities, food intake, other drugs)
How Is Fioricet Metabolized?
As Fioricet is a combination of 3 separate drugs, here are the ways the body metabolizes each one of these drugs:
Butalbital: This barbiturate is absorbed by the gastrointestinal tract, with a half-life of 35 hours. Elimination of the drug happens via the kidneys. Some metabolites can also be present in the urine sample.
Acetaminophen: The plasma half-life of acetaminophen is between 1 and 3 hours, and the elimination of the drug is by liver metabolism, followed by renal excretion of different metabolites. Acetemenephine is very hard on the liver for this reason and may cause liver failure.
Caffeine: Caffeine is rapidly absorbed by the body, with a plasma half-life of around 3 hours. The drug clears through the urine. It’s interesting to mention tests may find metabolites, but find only 3% unchanged caffeine.
Fioricet Half-Life & Duration of Action
One can feel the analgesic effects of Fioricet within 2 hours. These effects last between 4 and 6 hours.
As stated above, Butalbital has a long half-life (35 hours), which makes this drug intermediate-acting barbiturate.
Fioricet & Drug Testing
Although people don’t abuse barbiturates as they did a few decades ago, officials, companies or health professionals may still test for Fioricet. For instance, EIA (immunoassay technique) and GC/MS (gas chromatography/mass spectrometry) can detect barbiturates.
How Long Does Fioricet Stay in Blood?
Tests can detect Fioricet in blood. Tests can detect Butalbital intake for up to 72 hours.
How Long Does Fioricet Stay in Urine?
Urinalysis is among the most popular forms of drug testing. Although testing for the 3 ingredients of Fioricet is not universal, Fioricet detection in urine is possible. The detection time is up to 7 days.
How Long Does Fioricet Stay in Saliva?
Fioricet can be detected in swab tests, although it’s not a common procedure. The detectable levels in oral fluid show positive for up to 2 days.
How Long Does Fioricet Stay in Hair?
As most labs don’t do hair tests for Butalbital, there’s no precise data. However, have in mind that hair tests have a long window of detection (up to 90 days).
