Before you take a drug test, it’s important to answer the following question: Can prescription medication cause a false positive? The short answer — yes.
Here’s a list of medications that can cause a false positive:
- Amitriptyline — can test positive for LSD
- Bupropion (generic Wellbutrin) — can test positive for amphetamine, methamphetamine, and LSD
- Dextromethorphan (found in Robitussin, Delsym and other over-the-counter cough medications) — can test positive for opiates and PCP
- Diltiazem — can test positive for LSD
- Diphenhydramine (Benadryl) — can test positive for LSD
- Ibuprofen/Naproxen (Advil/Motrin and Aleve) — can test positive for barbiturates, THC (cannabinoid), and PCP.
And that’s just a few. Make sure to do your research before you go and get any type of blood work or drug testing done to ensure these false positives don’t happen to you.
