Hi,
Thanks for writing in.

Usually lexapro will not cause positive for amphetamines but there can be exceptions. It is said that verification of the test results with a different screening test or additional analytical tests should be performed to double confirm.

So you are saying a follow up test should be taken wouldnt the same results come up and would bloods be more accurate. Im also on modafinal and nexium would either og these drugs given a false positive at all.

Brief Answer:
Nexium can cause false positive test

Detailed Answer:
Hi,
Thanks for writing back with an update.

It is important to know that Nexium can cause false positive for THCs since it is a proton pump inhibitor.

Modafinil is unlikely to cause false positive drug test.

Please let your testing laboratory know that you take Nexium when you take the test again.

Hope your query is answered.
Please do write back if you have any doubts.
