How long will Benzodiazepine be detectable through urinalysis?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

How long will a Benzodiazepine that are Valium and Nitrazepam remain detectable through urinalysis? The drug has not been used for so long, maybe seven to eight days. What is the best method of detoxification?

Kindly help.

Hi,

Welcome to icliniq.com.

The duration for the urine toxicology screen being positive depends upon the type of Benzodiazepines being used. In light of the two drugs you mentioned, it may stay positive for a week or so. Regarding detox, there are two different ways of doing it and it depends upon the duration of use.

In your situation since it was just seven days of usage, I would suggest reducing your dose by 10% for every three to four days and tapering it off. If you are taking a higher dose, as I am not sure how much you are taking, you may have to taper even more slowly, such as 10% per week.

The other type of detox requires admission to a hospital and rapid detox with Flumazenil infusion, which I think is not for you since you used it for a short duration and are not addicted to it.

I hope this helps.
