Vicodin stays in your system for around 20 hours. However, “How long does Vicodin stay in your system?” is a more complicated question than you may think, as each body metabolizes drugs at different rates. Moreover, different drug tests can detect this powerful medication far beyond this time frame.
Keep reading to learn more about the metabolism and elimination of Vicodin and discover the key factors determining how long Vicodin stays in your system.
What Is Vicodin?
Vicodin is a potent opioid medication prescribed to treat moderate-to-severe pain resistant to non-opioid pain relievers. As a combination drug, it contains two active ingredients:
- Acetaminophen, an over-the-counter medication used to manage mild-to-moderate pain and treat fever
- Hydrocodone, a semi-synthetic derivative of codeine or thebaine, alkaloids naturally occurring in opioid poppy plants
Vicodin® is one of the brand names for generic acetaminophen/hydrocodone medication, which is also sold under some other brand names, including Norco®, Lortab®, and Lorcet®.
Brand-name Vicodin® comes in tablets containing 300 mg acetaminophen and 5 mg, 7.5 mg, or 10 mg hydrocodone, marketed as Vicodin®, Vicodin ES®, and Vicodin HP®, respectively. Meanwhile, generic acetaminophen/hydrocodone is also available as a liquid.
Acetaminophen/hydrocodone was the most commonly prescribed opioid in 2021. However, like any opioid medication, Vicodin has a high potential for opioid abuse, dependence, and addiction.
Although it was initially treated as a Schedule III controlled substance, Vicodin was reclassified as a Schedule II controlled substance in 2014. Nevertheless, it remains a popular street drug, with Vikes and Fluff being some of its most common street names.
To reduce the risks associated with Vicodin use, it is imperative to take the medication precisely as prescribed. Long-term hydrocodone use also increases the risk of addiction, dependence, and overdose, which is why it is not recommended to take Vicodin for chronic pain treatment.
How Does Vicodin Affect Your Body?
Vicodin affects the body by interacting with the opioid receptors in the central nervous system (CNS). Once consumed, it binds to these receptors, disrupting the transmission of pain signals between the body and the brain, which alters the perception of pain. Vicodin typically starts working within around 30 minutes of ingestion, with effects lasting for 4–8 hours.
While pain relief is the primary effect of Vicodin, it can also induce feelings of deep relaxation and euphoria by triggering a surge of dopamine in the brain. This further increases the risk of opioid abuse and addiction, as people are naturally wired to repeat actions that stimulate dopamine release.
Besides pain relief, relaxation, and euphoria, Vicodin can cause various side effects, ranging from mild to potentially life-threatening.
Some common Vicodin side effects are:
- Itchy skin
- Dizziness
- Headache
- Dry mouth
- Drowsiness
- Constipation
- Blurred vision
- Trouble urinating
- Nausea and vomiting
While some of these may resolve independently, others may require medical attention. Therefore, it’s best to inform your doctor about any side effects you experience while taking this medication.
Vicodin Half-Life
Vicodin’s half-life is around 3.8 hours, which means that it takes around four hours for the body to eliminate half a dose of the drug. However, it takes five half-lives on average to fully clear opioids out of the system, and Vicodin is no exception.
With this in mind, let’s dissect the question, “How long does Vicodin stay in your system?” and find out how long it remains detectable in different drug tests.
How Long Does Vicodin Stay in Your System?
Vicodin stays in your system for around 20 hours, as the half-life of Vicodin is roughly four hours.
However, “How long does Vicodin stay in your system?” and “How long can Vicodin be detected in drug tests?” are two different questions. Some drug tests may detect traces of its active opioid ingredient—hydrocodone—even months after the last dose, while others may only detect it for a day or two.
Let’s discuss the Vicodin detection times for blood, saliva, urine, and hair tests.
How Long Does Vicodin Stay in Blood?
Vicodin stays in the blood and remains detectable in blood samples for up to 24 hours after the last dose. While blood tests are quite accurate, they have the shortest detection window for Vicodin. They are also more invasive and expensive than other forms of drug testing.
How Long Does Vicodin Stay in Hair?
Vicodin stays in the hair for up to 90 days after taking the last dose. Hair follicle tests are conducted on a 1.5-inch hair sample containing the follicle. Since these tests can detect whether you’ve used Vicodin in the last three months, they have the longest detection window but can be rather costly.
How Long Does Vicodin Stay in Saliva?
Vicodin stays in saliva and can be detected in saliva samples for around 48 hours following the last dose. Most saliva tests are performed by sending an oral swab to the laboratory for inspection, and they are usually quite reliable and non-invasive.
How Long Does Vicodin Stay in Urine?
Vicodin stays in the urine for up to four days after taking the last dose. Urine tests are quite popular, as they are easy to administer, have a relatively long detection window compared to blood and saliva tests, and are usually fairly affordable.
It’s worth noting that various individual factors, such as your metabolism, may affect the elimination of Vicodin and alter the above-mentioned detection windows. Therefore, the answer to “How long does Vicodin stay in your system?” may vary from one person to the next.
Let’s explore the factors that determine how long Vicodin stays in your system in greater detail.
Factors That Determine How Long Vicodin Stays in Your System
Liver and kidney health are among the key factors that determine how long Vicodin stays in your system, as hydrocodone is metabolized mainly in the liver and primarily undergoes renal excretion. Impaired liver or kidney function may cause Vicodin to stay longer in your system, increasing the risk of opioid toxicity.
Hydrocodone is generally not recommended for patients with hepatic impairment. The hydrocodone/acetaminophen combination, in particular, has been linked to acute liver injury and may not be suitable for those with liver disease.
Other factors that determine how long Vicodin stays in your system include:
- Metabolism. The faster your metabolism is, the less time your body will need to break down Vicodin and flush it out. Body composition, age, physical activity level, diet, and other factors that may affect your metabolic rate can also impact the elimination of Vicodin.
- Extent of Vicodin use. The dosage, frequency, and duration of opioid use play an important role in determining how long Vicodin stays in your system. Put simply, your body will have an easier time processing and eliminating Vicodin if you’ve been taking it in minimal doses for a short time as opposed to in large doses for a prolonged period.
- Use of other substances. Certain substances, including prescription drugs and herbal supplements, may hinder your body’s ability to metabolize and eliminate Vicodin effectively. Never take Vicodin with other substances your doctor hasn’t approved of, as this may also increase the risk of unwanted side effects, Vicodin overdose, and even death.
Vicodin Addiction vs. Vicodin Dependence
Vicodin addiction and Vicodin dependence are two distinct yet often co-occurring conditions that anyone taking this medication risks developing.
Vicodin dependence refers to the physical dependence that anyone taking this drug for an extended time will eventually develop. Since repeated opioid exposure causes the brain to stop producing endorphins and create more opioid receptors, even those who take Vicodin as prescribed can become dependent on it.
Tolerance and opioid withdrawal symptoms signify a dependence on Vicodin. Once you become dependent, your usual dose will no longer suffice; eventually, you won’t feel the drug’s effects without increasing the dosage.
Moreover, people dependent on Vicodin have to rely on it to function normally, as the absence of the drug leads to vomiting, body aches, cravings, and other uncomfortable withdrawal symptoms. If left untreated, Vicodin dependence can develop into Vicodin addiction, also known as opioid use disorder (OUD).
Vicodin addiction is primarily psychological. Sadly, those addicted to opioids lose control over their impulses and cannot stop taking them, even when it negatively affects their relationships, careers, and so forth.
Given that prescription drug addiction may lead to illicit drug use and significantly increase the risk of opioid overdose and death, getting professional opioid addiction treatment is of utmost importance.
Vicodin Withdrawal Symptoms
Vicodin withdrawal symptoms occur when people dependent on this medication attempt to quit it or reduce their dosage, especially suddenly.
The most common Vicodin withdrawal symptoms include:
- Anxiety
- Nausea
- Diarrhea
- Yawning
- Vomiting
- Shivering
- Depression
- Dilated pupils
- Loss of appetite
- Excessive sweating
- Muscle and joint aches
- Difficulty falling or staying asleep
- Changes in blood pressure and heart rate
- Flu-like symptoms, such as fever and runny nose
Since the half-life of Vicodin is relatively short, you may experience the first withdrawal symptoms within just 12–24 hours after your last Vicodin dose. While these symptoms typically subside within a week, it’s not unusual for people to suffer from cravings, insomnia, and depression for weeks and even months after discontinuing Vicodin.
Importantly, going through Vicodin withdrawal puts you at a high risk of relapse. If you relapse, even your usual dose may be potent enough to cause a potentially fatal opioid overdose. This, coupled with the fact that Vicodin withdrawal can lead to life-threatening complications like extreme dehydration, explains why you should never quit Vicodin without medical supervision.
ANR Opioid Dependence Treatment
Accelerated Neuro-Regulation (ANR) is a groundbreaking treatment that eradicates opioid dependence by restoring the brain to its pre-addiction state.
Developed by Dr. Andre Waismann, ANR has helped close to 25,000 people worldwide overcome opioid dependence and return to an opioid-free life without the fear of relapse.

Key Takeaways
While the general answer to “How long does Vicodin stay in your system?” is 20 hours, the rate at which the body processes and clears this medication largely depends on your health, metabolism, the extent of Vicodin use, and whether or not you’re taking any other substances.
Now, let’s reiterate the key points we covered:
- Vicodin is a prescription opioid pain medication made up of acetaminophen and hydrocodone.
- Vicodin can be detected in blood for around 24 hours, in saliva for about 48 hours, in urine for up to four days, and in hair follicle samples for up to three months after ingestion.
- ANR is a modern opioid dependence treatment that can help you safely overcome Vicodin dependence within days.
How Long Does Vicodin Stay in Your System FAQ
It takes around 20 hours to get Vicodin out of the system. However, this may also depend on various individual factors, such as your liver and kidney function, metabolism, and the extent of your Vicodin use.
Vicodin is primarily eliminated from the body through the urine after being metabolized in the liver. Both acetaminophen and hydrocodone are primarily excreted through urine, with around 6.5% of the hydrocodone dose being excreted remains unchanged by the kidneys.
You may feel drowsy and relaxed after taking Vicodin, as it not only relieves pain but also induces a state of euphoria, enhancing its potential for abuse and addiction. You might also experience side effects like nausea, dry mouth, and lightheadedness after ingesting Vicodin. Inform your doctor about any unwanted effects you experience while taking Vicodin.
Vicodin takes around 30 minutes to work, though the onset of its effects may also depend on the dose and other individual factors. Never take Vicodin more frequently or in higher doses than prescribed, as this constitutes opioid abuse and may lead to dangerous side effects, dependence, addiction, overdose, and death.
Vicodin is very addictive. While acetaminophen isn’t addictive, it is possible to become addicted to hydrocodone, the opioid ingredient in Vicodin. Anyone taking opioids, including hydrocodone, for a prolonged time can become dependent and develop an opioid addiction.
The peak time for Vicodin is around 1.3 hours post-ingestion. It takes just above an hour for hydrocodone to reach peak concentrations in the bloodstream, whereas the pain-relieving effects of acetaminophen peak within an hour or two following consumption.
Some drugs stronger than Vicodin include fentanyl and hydromorphone (Dilaudid®). Although some opioid medications are stronger than hydrocodone, all opioids should be taken strictly as prescribed to reduce the risk of dependence, addiction, and overdose.
