How Long Does Hydrocodone Stay in Your System?
Quick Answer
Hydrocodone is detectable for roughly 1 day in blood, up to 3 days in urine, about 1–3 days in saliva, and up to 90 days in hair. It leaves the bloodstream in about a day but shows up longest in hair testing.
Duration by Type
Up to about 24 hours.
Roughly 12–36 hours.
Up to about 90 days.
Quick Answer
Hydrocodone has a half-life of about 4 hours, so it clears the bloodstream within roughly a day. But because different tests detect it for different lengths of time, the answer ranges from about 1 day (blood) up to 90 days (hair). Most standard urine drug tests can detect hydrocodone or its metabolites for 2–4 days after the last dose.
Detection Windows by Test Type
| Test Type | Detection Window |
|---|---|
| Blood | Up to 24 hours |
| Saliva | 12–36 hours |
| Urine | 2–4 days |
| Hair | Up to 90 days |
How Hydrocodone Is Processed
Hydrocodone is an opioid that the liver breaks down—partly into hydromorphone, an active metabolite. Its half-life of about 3.8 hours means half the drug is eliminated roughly every 4 hours. It generally takes 4–5 half-lives, or about a day, for the body to clear a single dose from the blood. However, metabolites linger longer in urine, and hair captures a long historical record as the drug is deposited into growing strands.
Factors That Affect How Long It Stays
- Metabolism and age — faster metabolisms and younger people clear it sooner.
- Liver and kidney function — impaired organs slow elimination significantly.
- Dose and frequency — higher or repeated doses take longer to clear.
- Extended-release formulations — these release the drug slowly, extending detection.
- Body composition and hydration — affect concentration and clearance rate.
- Other medications — some drugs speed or slow liver enzymes that metabolize hydrocodone.
Can You Speed Up Clearance?
There is no reliable, safe way to flush hydrocodone from your system faster. Staying hydrated, eating well, and light exercise support normal liver and kidney function, but they will not dramatically shorten detection windows. "Detox" products marketed to beat drug tests are not proven and can be dangerous. Time is the only dependable factor.
When to See a Doctor
Seek emergency care immediately for signs of a hydrocodone overdose: slow or stopped breathing, extreme drowsiness or inability to wake, pinpoint pupils, or bluish lips and fingertips. Naloxone (Narcan) can reverse an overdose. Talk to a doctor if you feel you cannot stop taking hydrocodone, need higher doses for the same effect, or experience withdrawal symptoms like anxiety, sweating, nausea, and muscle aches when a dose is missed. Opioid dependence is treatable, and help is available.
Pro Tips

— MedlinePlus
Keep naloxone (Narcan) on hand if you or someone you know uses opioids; it can reverse an overdose.
— SAMHSA
Never combine hydrocodone with alcohol or sedatives, which sharply raise overdose risk.
