If i'm on methadone maintenance program, and i took midrin for head aches, will this show on a drug screen?

Probably Not: As far as i know there are no barbiturates in midrin. One of the components does breakdown to Chloral Hydrate but that substance is seldom tested for as the actual drug is not frequently tested for except in forensic situations as for when a date-rape drug is suspected. Chloral hydrate is seldom prescribed-is the drug used in a mickey finn.

Yes: Yes. The barbiturate butalbital is in midrib and can bet detected in a urine drug screen.

Possibly: I have seen where Midrin caused a positive result for amphetamines on a patient's drug test on more than a few occasions. My advice would be for you to tell them at your clinic that you took Midrin rather than having to explain yourself if you have a positive test. I know i always appreciated that from patients and would be less likely to hold it against them.
