Certain factors affect how long Norco stays in your system. Norco can be detected for up to 90 days after the last dose, but different drug tests have different windows of detection. The longevity of Norco in a person’s system is influenced by factors, including:

  • Dosage
  • Frequency and length of drug use
  • Body fat
  • Metabolism rate
  • Kidney and liver health
  • Age
  • A family history of drug abuse or addiction

What is Norco?

Norco is a combination of hydrocodone ⏤ a highly addictive opioid derived from codeine ⏤ and acetaminophen. Norco is used to treat pain and can also be prescribed as a cough suppressant. Hydrocodone changes the way the brain manages pain. The result is a very pleasant sensation of tranquility and relaxation. These euphoric effects are largely responsible for the prevalence of hydrocodone addiction in the United States.

Over time, the brain begins craving those pleasant feelings, and it becomes increasingly challenging for people who take Norco to control how and when they use it. This behavior results in drug misuse, addiction and overdose. Common signs of overdose include:

  • Breathing problems
  • Low blood pressure
  • Weak pulse
  • Confusion
  • Dizziness
  • Drowsiness
  • Weakness
  • Clammy skin
  • Nausea and vomiting
  • Blue lips or fingernails
  • Loss of consciousness
  • Coma

Norco Half-Life

The half-life of Norco is about 4 hours. A half-life is how long it takes a person’s body to eliminate half the amount of the drug from their bloodstream. Norco is usually eliminated from a person’s body within 24 hours of the latest dose. However, due to the metabolites Norco leaves behind, the drug is detectable for much longer when utilizing urine, hair and saliva tests.

How Long Does Norco Stay in Urine?

Urine screening is commonly used to look for evidence of Norco in a person’s system. Norco can be detected in urine immediately after the last dose and for up to four days afterward.

How Long Does Norco Stay in Hair?

Norco can be detected via hair follicle testing for seven to 10 days after a person’s last dose. Norco remains detectable in hair up to 90 days after use. The hair follicle test is not affected by washing, styling or bleaching.

How Long Does Norco Stay in Saliva?

Norco can be detected in saliva five to 10 minutes after the last dose is taken. It remains detectable for up to 24 hours.
