As with any other benzodiazepine like Xanax, Librium has a long half-life. The time taken to eliminate the drug from the body can vary between people. Librium has a half-life from five to 30 hours. This means that 50 percent of the drug gets eliminated within this timeframe. Users may take Librium for a short or extended timeframe depending on the treatment they seek. When stopping Librium use, the time taken to eliminate the drug entirely from the body depends on a range of factors.
Age
Bodyweight and mass
Period of usage and dosage
Liver function
Genetics
Other drugs in the system
The body primarily clears Librium through the liver, but some of the drugs may even get excreted through urine. Liver health will impact how quickly the drug clears from the body’s system. Since liver function reduces with age, older people eliminate Librium much slower than younger people.
Similarly, obese people with a higher BMI will take longer to eliminate Librium than regular weight people. Factors like dosage and period of use also play a role in how long it takes for Librium to clear from the body.
