Will the medication Dilantin cause a false positive for barbiturates?

Question

I had to take a drug screening and it came back positive for barbiturates. I take the anticonvulsant Dilantin. I want to know if the Dilantin could cause this to happen? I don't take anything other than the Dilantin.

From what I found, it looks like Dilantin could cause false positive for barbs. You should suggest that the test be redone and they should use a more specific test to differentiate Dilantin and barbs.
See the website listed in the source below.
Keep in mind to always let the medical staff know of all medications you're on, including herbals and over the counter drugs too.

Answer 2

i can't say for sure if it can or not. Call you pharmaacist and ask them. i am sure that they can tell you. When you do a drug screen they do ask about medications that you take both prescribed and otc. You need to let them know that you take Dilantin. Take you prescription bottle to them and they will make a copy of it.
