Naproxen sodium 220 mg 4x per day, Ibuprofen, Aleve, Melatonin, Allergy medication (benadryl, equate brand), eye drops for allergy relief (they have antihistamines). I took two Naproxen sodiums 10 minutes before a UA and it showed I was positive for PCP. I am freaking out because I don't use illegal substances but I am a recovering alcoholic. I've never been into drugs and when the tech said I was testing positive for PCP I nearly broke down into a panic attack because I don't even know what PCP is. Please tell me it's one of these OTC meds that's causing this. How long can they last in my body? They sent the UA sample to a lab yesterday so how long should it take for the results to get back?
Can these OTC meds cause false positive for PCP?

Could eye drops also possibly cause a false positive?

Some reported medications that may cause a false positive for PCP include drugs containing things like pseudoephedrine (like Sudafed and the many meds it's also combined with like Allegra-D, and Chlorpheniramine Maleate), dextromethorphan containing meds, some asthma medications (like Primatene). Some of the most commonly reported false positives are from drugs like: Effexor, Lamictal, Seroquel, Provigil, or drugs that react similarly in the body.
Hope you get it figured out.
