How Long Does Hydrocodone Stay in Your System? (2025 Guide)
Hydrocodone is a prescription opioid used for moderate to severe pain. Because of its potency and potential for dependence, many people want to know how long hydrocodone remains in the body and how long it can be detected on a drug test. This guide explains hydrocodone detection times, half life, and the factors that influence how long it stays in your system.
On average, hydrocodone stays in the system for 1 to 4 days. However, detection times vary depending on the type of test, dosage, metabolic rate, and how frequently the medication is used.
Hydrocodone Detection Times by Test Type
Below are general detection windows for hydrocodone and its metabolites:
| Test Type | Detection Window |
|---|---|
| Urine | 1 to 4 days |
| Blood | Up to 24 hours |
| Saliva | 1 to 2 days |
| Hair | Up to 90 days |
Some drug tests look for hydrocodone metabolites such as hydromorphone or norhydrocodone, which may remain detectable slightly longer.
Hydrocodone Half Life
Hydrocodone has an average half life of 3.5 to 9 hours, depending on the formulation and individual factors. This means half the drug is eliminated from the bloodstream within this time frame. Extended release formulations may remain detectable longer.
- Immediate-release hydrocodone: shorter half life
- Extended-release hydrocodone: longer duration and metabolism period
Factors That Influence Detection Time
Several variables affect how long hydrocodone stays in the system:
- Frequency of use – repeated use accumulates in the body
- Dosage strength
- Formulation (IR vs ER)
- Age and metabolism rate
- Liver and kidney health
- Hydration levels
- Body fat percentage
How Long Do the Effects of Hydrocodone Last?
The effects of hydrocodone depend on the formulation:
- Immediate-release: 4 to 6 hours
- Extended-release: up to 12 hours or longer
Common effects include slowed breathing, drowsiness, reduced pain, and impaired coordination.
Risks of Hydrocodone Misuse
Although hydrocodone is commonly prescribed, it has a high potential for dependence and misuse. Taking more than prescribed or using the medication without a prescription increases the risk of addiction and overdose.
- Respiratory depression
- Dependence or withdrawal symptoms
- Constipation
- Impaired coordination
- Increased tolerance
- Risk of overdose
Signs of Hydrocodone Misuse
- Using higher doses than prescribed
- Cravings or preoccupation with the medication
- Mood changes or irritability
- Doctor shopping or early refill requests
- Withdrawal symptoms when trying to stop
