Medications and Drug Test

Medications and drug test results can cause considerable confusion. Various medications and other products (such as poppy seeds) can produce non-negative test results on screening kits in urine or saliva drug testing.

Note: The following cross re-activity information and tables may be referred to as a potential cause of non-negative drug screen results when subjects are taking proprietary medications.

  • This information is not medical advice
  • Consult with your doctor for the most suitable medication for you
  • There may be additional medications not listed below; as new medications are continually introduced
  • Some medications listed below may not produce the results indicated in certain circumstances
  • All non-negative screening test results must be referred to a confirmatory laboratory
