Will claritin make me test positive on a drug screen?

Generally, if you fail your urine test, (and I have a few times), they send the urine off to be tested more thoroughly at a major lab. That is where they can pick up meds such as allergy meds in your urine. Tell them everything you take including supplements, (that's what my problem was, I take a TON of supplements), and don't worry>

I have heard lots of complaints about people failing their urine tests becasue of using allergy & cold meds. Be sure to tell them you take it before the test...
