How long do barbiturates (Fiorinal/ Butalbital) stay in your system? When could I pass a urine drug test?
I took the pain killer for a migraine, but it wasn't prescribed to me. I know that's not good, but I was desperate. But I have a urine drug test. I'm certainly not a user, but I'm concerned. I took it Saturday July 5, and my test is Monday July 14. Will I pass?
I have researched your question and I have found no Half -Life to this drug. This generally means that it does not stay in your system for very long.
If you want to pass your drug test, here's how.
When you wake up the morning of your test, urinate. If youy have to urinate again before your test go ahead and do so. Do not urinate two hours before your test. This is were it gets nasty. Take two shots (2 ounces) of Vinegar two hours before your test. You can drink water and/or anything acidic (grapefruit/orange juice) but do not pee until your test.
Your urine will show that it is acidic but it covers the Butalbital in your system.
Good Luck!

If you only took it one time and it was a low dose you should be fine.
Usually takes 7-14 days.

Decreasing detection times:
Increasing metabolism is probably the most effective way to decrease the time period that drugs can be detected in your system. Physical activity can increase your metabolic rate.
